本发明涉及对显示部进行保护的显示器用保护片及由显示器用保护片实施了保护的显示装置。The present invention relates to a protective sheet for a display that protects a display unit, and a display device protected by the protective sheet for a display.
背景技术Background technique
当前，使用如下显示装置，即，使设置有压敏式的触摸面板即显示部的显示器从在操作盘形成的开口露出。例如，在专利文献1中公开了如下结构，即，为了保护显示部，用保护片将显示部的表面覆盖。Conventionally, a display device is used in which a display provided with a display unit which is a pressure-sensitive touch panel is exposed from an opening formed in the operation panel. For example, Patent Document 1 discloses a structure in which the surface of the display unit is covered with a protective sheet in order to protect the display unit.
压敏式的触摸面板通过对触碰显示部时的压力进行感知，从而对显示部被操作这一情况进行检测。因此，为了可靠地对触碰显示部时的压力进行感知而谋求将显示部覆盖的保护片的薄化。A pressure-sensitive touch panel detects that the display unit is operated by sensing pressure when the display unit is touched. Therefore, in order to reliably sense the pressure when the display unit is touched, the protective sheet that covers the display unit is required to be thinned.

发明内容Contents of the invention
但是，就实现了薄化的保护片而言，其刚性会降低。就刚性降低的保护片而言，通过对外周缘施加压力，从而在外周缘发生变形，变得容易剥落。根据使用环境，有时通过高压清洗机清洗显示装置。由于来自高压清洗机的水流的碰撞，因此存在保护片的外周缘变形，保护片从该变形部分剥落的风险。因此，有时要求对显示部进行保护的显示器用保护片可耐受由高压清洗机进行的清洗而难以剥落。However, the rigidity of the thinned protective sheet decreases. In the case of a protective sheet whose rigidity is lowered, the outer peripheral edge is deformed by applying pressure to the outer peripheral edge, and it becomes easy to peel off. Depending on the usage environment, the display unit may be cleaned with a high-pressure cleaner. Due to the impact of the water flow from the high-pressure washer, the outer peripheral edge of the protective sheet is deformed, and the protective sheet may peel off from the deformed portion. Therefore, it may be required that the protective sheet for a display which protects the display part endures washing with a high-pressure cleaner and is difficult to peel off.
本发明就是鉴于上述问题而提出的，其目的在于得到能够实现耐剥离性的提高的显示器用保护片。This invention was made in view of the said subject, and it aims at obtaining the protective sheet for displays which can improve peeling resistance.
为了解决上述课题，达成目的，本发明涉及的显示器用保护片以比显示器的显示部大的尺寸形成，将显示部覆盖。另外，显示器用保护片的特征在于，与将显示部覆盖的中央区域的刚性相比，将中央区域的周围包围的外周区域中的至少成为与显示部侧相反侧的表面侧的刚性高。In order to solve the above-mentioned problems and achieve the object, the protective sheet for a display according to the present invention is formed in a size larger than the display portion of the display, and covers the display portion. In addition, the protective sheet for a display is characterized in that at least the surface side opposite to the display part side in the outer peripheral region surrounding the central region has higher rigidity than the central region covering the display part.
发明的效果The effect of the invention
本发明涉及的显示器用保护片取得如下效果，即，能够实现耐剥离性的提高。The protective sheet for a display according to the present invention has the effect that the improvement in peeling resistance can be achieved.

具体实施方式Detailed ways
下面基于附图对本发明的实施方式涉及的显示器用保护片及显示装置进行详细说明。此外，本发明并不限定于本实施方式。Hereinafter, the protective sheet for displays and the display device according to the embodiments of the present invention will be described in detail based on the drawings. In addition, this invention is not limited to this embodiment.
实施方式1.Implementation mode 1.
图1是本发明的实施方式1涉及的显示装置的正视图。图2是沿着图1所示的II-II线切断的剖视图。显示装置10具备：显示器1，其设置有成为压敏式的触摸面板的显示部1a；安装盘2，在该安装盘2安装显示器1；以及显示器用保护片3，其覆盖显示部1a。FIG. 1 is a front view of a display device according to Embodiment 1 of the present invention. Fig. 2 is a cross-sectional view taken along line II-II shown in Fig. 1 . The display device 10 includes: a display 1 provided with a display portion 1a serving as a pressure-sensitive touch panel; a mounting plate 2 on which the display 1 is mounted; and a display protection sheet 3 covering the display portion 1a.
在显示器1的显示部1a显示各种信息。使用者如果对显示出目标信息的部分进行触碰，则根据压力的变化而感知到所触碰的位置，判断为进行了向在该位置显示的信息的接触操作。Various kinds of information are displayed on the display unit 1 a of the display 1 . When the user touches the portion where the target information is displayed, the touched position is sensed by a change in pressure, and it is determined that a touch operation is performed on the information displayed at the position.
在安装盘2形成有供显示器1的显示部1a插入的显示部开口21。显示器1在将显示部1a从安装盘2的背面2b侧插入的状态下，由安装金属件4固定于安装盘2。显示器1在固定于安装盘2的状态下，安装盘2的表面2a和显示部1a成为同一个面。A display portion opening 21 into which the display portion 1 a of the display 1 is inserted is formed in the mounting plate 2 . The display 1 is fixed to the mounting plate 2 by the mounting metal fitting 4 in a state where the display portion 1 a is inserted from the rear surface 2 b side of the mounting plate 2 . In the state where the display 1 is fixed to the mounting plate 2, the surface 2a of the mounting plate 2 and the display part 1a become the same surface.
显示器用保护片3粘附于安装盘2的表面2a。图3是将图2所示的A部分放大的局部放大剖视图。此外，在图3中，省略显示器1。就显示器用保护片3而言，从安装盘2的表面2a侧观察，整体以比显示器1的显示部1a大的尺寸形成，将显示部1a覆盖。此外，在下面的说明中，将从安装盘2的表面2a侧观察称为正视观察。A protective sheet 3 for a display is adhered to the surface 2 a of the mounting pad 2 . Fig. 3 is a partially enlarged cross-sectional view enlarging a portion A shown in Fig. 2 . In addition, in FIG. 3 , the display 1 is omitted. The protection sheet 3 for a display is formed in a size larger than the display part 1a of the display 1 as a whole when viewed from the surface 2a side of the mounting board 2, and covers the display part 1a. In addition, in the following description, observation from the surface 2a side of the mounting board 2 is called frontal observation.
显示器用保护片3具有：中央区域3a，其将显示部1a覆盖；以及外周区域3b，其将中央区域的周围包围。显示器用保护片3具有第1片材31和第2片材32。第1片材31是横跨中央区域3a及外周区域3b而设置的。第1片材31由PET(Polyethylene terephthalate)形成。The protective sheet 3 for a display has the central region 3a which covers the display part 1a, and the peripheral region 3b which surrounds the periphery of a central region. The protective sheet 3 for a display has a first sheet 31 and a second sheet 32 . The first sheet 31 is provided across the central region 3a and the outer peripheral region 3b. The first sheet 31 is formed of PET (Polyethylene terephthalate).
第1片材31通过粘结部即双面胶带22粘附于安装盘2的表面2a中的将显示部开口21包围的部分。此外，粘接部也可以使用粘结剂。此外，第1片材31的厚度例如为0.125mm。The first sheet 31 is adhered to a portion of the surface 2 a of the mounting board 2 surrounding the display portion opening 21 through a double-sided adhesive tape 22 that is an adhesive portion. In addition, an adhesive may be used for the bonding portion. In addition, the thickness of the first sheet 31 is, for example, 0.125 mm.
就第2片材32而言，在与第1片材31的中央区域3a的部分重叠的区域设置开口33，第2片材32整体呈框状的形状。第2片材32通过双面胶带23从表面侧粘附于第1片材31的外周区域3b部分。由此，在正视观察时，在中央区域3a，第1片材31从开口33露出，在外周区域3b，表面侧被第2片材32覆盖。第2片材32由PC(Polycabonate)形成。另外，第2片材32的厚度为比第1片材31厚的厚度，例如设为1mm。In the second sheet 32, the opening 33 is provided in a region overlapping with the central region 3a of the first sheet 31, and the second sheet 32 has a frame-like shape as a whole. The second sheet 32 is adhered to the outer peripheral region 3 b of the first sheet 31 from the front side with the double-sided tape 23 . Thereby, when viewed from the front, the first sheet 31 is exposed from the opening 33 in the central region 3a, and the front side is covered with the second sheet 32 in the outer peripheral region 3b. The second sheet 32 is formed of PC (Polycabonate). In addition, the thickness of the 2nd sheet|seat 32 is thicker than the 1st sheet 31, for example, it is 1 mm.
另外，第2片材32的外周缘的成为表面侧的角部成为进行了倒角的倒角部32a。另外，第2片材32中的与安装盘2相对的面成为实施了涂装的涂装面35。由于第2片材32中的与安装盘2相对的面没有露出，因此不会发生涂装材料的剥落。因此，能够有助于对显示装置10进行设置的空间的清洁性的提高。另外，通过使用如PC那样的透明材料，从而能够经过第2片材32对在与安装盘2相对的面实施的涂装进行视觉辨认。由此，能够实现基于涂装的设计性的提高。Moreover, the corner part which becomes the surface side of the outer peripheral edge of the 2nd sheet|seat 32 becomes the chamfered part 32a which was chamfered. In addition, the surface of the second sheet 32 that faces the mounting board 2 is a painted surface 35 that has been painted. Since the surface of the second sheet 32 facing the mounting board 2 is not exposed, peeling of the coating material does not occur. Therefore, it is possible to contribute to the improvement of the cleanliness of the space where the display device 10 is installed. In addition, by using a transparent material such as PC, the coating applied to the surface facing the mounting board 2 can be visually recognized through the second sheet 32 . Thereby, the improvement of the designability by painting can be aimed at.
在以上说明的显示装置10中，相比于在显示器用保护片3的中央区域3a设置的第1片材31，在外周区域3b的表面侧设置的第2片材32的刚性高。In the display device 10 described above, the second sheet 32 provided on the front side of the outer peripheral region 3 b has higher rigidity than the first sheet 31 provided on the central region 3 a of the display protection sheet 3 .
因此，对外周缘而言，即使从高压清洗机喷出的水流碰撞至显示器用保护片3的外周缘和安装盘2之间的边界附近，显示器用保护片3的外周缘也变得难以变形。由此，难以发生显示器用保护片3从安装盘2的剥落。另外，在外周区域3b也设置有刚性低的第1片材31，但通过被在外周区域3b的表面侧设置的刚性高的第2片材32按压而抑制了变形，因此从该观点出发也难以发生显示器用保护片3从安装盘2的剥落。Therefore, the outer peripheral edge of the display protective sheet 3 is less likely to be deformed even if the water stream jetted from the high-pressure cleaner collides near the boundary between the outer peripheral edge of the display protective sheet 3 and the mounting board 2 . Thereby, peeling of the protective sheet 3 for a display from the mounting board 2 is hard to generate|occur|produce. In addition, although the first sheet 31 with low rigidity is also provided in the outer peripheral region 3b, deformation is suppressed by being pressed by the second sheet 32 with high rigidity provided on the surface side of the outer peripheral region 3b. Peeling of the protective sheet 3 for a display from the mounting board 2 hardly occurs.
另外，通过在第2片材32形成倒角部32a，从而能够释放由水流的碰撞产生的压力，能够进一步抑制显示器用保护片3从安装盘2的剥落。In addition, by forming the chamfered portion 32 a on the second sheet 32 , the pressure due to the impact of the water flow can be released, and the peeling of the display protection sheet 3 from the mounting board 2 can be further suppressed.
另外，通过在显示器用保护片3的外周区域3b提高表面侧的刚性而抑制剥落，并且在中央区域即将显示部1a覆盖的部分抑制刚性，从而在使用者触碰时，能够更可靠地对压力的变化进行感知。In addition, by increasing the rigidity of the surface side in the outer peripheral region 3b of the protective sheet 3 for a display to suppress peeling, and suppressing the rigidity in the central region that covers the display portion 1a, it is possible to more reliably resist the pressure when the user touches it. perception of changes.
另外，由于安装盘2的表面2a和显示器1的显示部1a成为同一个面，因此即使将由显示器用保护片3形成的凹凸也考虑在内，与使显示部1a凸出至安装盘2的表面2a侧的情况相比，也能够减少安装盘2的表面2a侧的凹凸。由此，尘埃难以附着于安装盘2的表面2a，能够有助于对显示装置10进行设置的空间的清洁性的提高。In addition, since the surface 2a of the mounting board 2 and the display portion 1a of the display 1 are on the same surface, even if the unevenness formed by the protective sheet 3 for a display is taken into consideration, it is not the same as making the display portion 1a protrude from the surface of the mounting board 2. The unevenness on the surface 2a side of the mounting pad 2 can also be reduced compared to the case on the 2a side. This prevents dust from adhering to the surface 2 a of the mounting board 2 , and contributes to improvement of the cleanliness of the space in which the display device 10 is installed.
图4是表示显示器用保护片3的变形例1的局部放大剖视图，并且是相当于图2所示的A部分的图。此外，在图4中，省略显示器1。在变形例1中，以将覆盖中央区域3a的第1片材31的周围包围的方式设置第2片材32。即，在正视观察时不具有第1片材31和第2片材32重叠的区域。而且，第2片材32的内周缘和第1片材31的外周缘通过粘结、压接、或二色成型进行接合。另外，第2片材32通过双面胶带23直接粘附于安装盘2的表面2a。在如上所述构成的情况下，也能够通过将外周区域3b的刚性设为比显示器用保护片3的中央区域3a高，从而抑制发生从外周缘的剥落。FIG. 4 is a partially enlarged cross-sectional view showing Modification 1 of the protective sheet 3 for a display, and is a view corresponding to part A shown in FIG. 2 . In addition, in FIG. 4 , the display 1 is omitted. In Modification 1, the second sheet 32 is provided so as to surround the first sheet 31 covering the central region 3 a. That is, there is no region where the first sheet 31 and the second sheet 32 overlap when viewed from the front. Furthermore, the inner peripheral edge of the second sheet 32 and the outer peripheral edge of the first sheet 31 are bonded by bonding, crimping, or two-color molding. In addition, the second sheet 32 is directly adhered to the surface 2 a of the mounting board 2 with the double-sided tape 23 . Also in the case of the above configuration, the occurrence of peeling from the outer peripheral edge can be suppressed by making the rigidity of the outer peripheral region 3 b higher than that of the central region 3 a of the protective sheet 3 for a display.
图5是表示显示器用保护片3的变形例2的局部放大剖视图，并且是相当于图2所示的A部分的图。此外，在图5中，省略显示器1。在变形例2中，第2片材32通过双面胶带23粘附于第1片材31的外周部。而且，在安装盘2的表面2a中的正视观察时与第1片材31及第2片材32重叠的部分，以大于或等于第1片材31的厚度和第2片材32的厚度之和的深度形成有槽25。而且，第1片材31的外周部通过双面胶带22粘附于槽25的底部。FIG. 5 is a partially enlarged cross-sectional view showing Modification 2 of the protective sheet 3 for a display, and is a view corresponding to part A shown in FIG. 2 . In addition, in FIG. 5 , the display 1 is omitted. In Modification 2, the second sheet 32 is adhered to the outer peripheral portion of the first sheet 31 with the double-sided tape 23 . Moreover, the portion overlapping the first sheet 31 and the second sheet 32 when viewed from the front on the surface 2a of the mounting plate 2 is greater than or equal to the thickness of the first sheet 31 and the thickness of the second sheet 32. A groove 25 is formed with a depth of . Furthermore, the outer peripheral portion of the first sheet 31 is adhered to the bottom of the groove 25 with the double-sided tape 22 .
更具体而言，本变形例2中的槽25的深度等于第1片材31的厚度、第2片材32的厚度和双面胶带22、23的厚度之和。由此，如图5所示第2片材32与安装盘2的表面2a成为同一个面。由此，能够减少尘埃容易积存的凹凸部位，有助于对显示装置10进行设置的空间的清洁性的提高。More specifically, the depth of the groove 25 in Modification 2 is equal to the sum of the thickness of the first sheet 31 , the thickness of the second sheet 32 , and the thicknesses of the double-sided tapes 22 and 23 . Thereby, as shown in FIG. 5, the 2nd sheet|seat 32 becomes the same surface as the surface 2a of the mounting board 2. As shown in FIG. Accordingly, it is possible to reduce unevenness where dust tends to accumulate, and contribute to improvement of the cleanliness of the space in which the display device 10 is installed.
另外，由于显示器用保护片3的外周缘嵌入至槽25，因此水流变得难以直接碰撞到外周缘。由此，能够使显示器用保护片3进一步难以剥落。In addition, since the outer peripheral edge of the protective sheet 3 for a display is fitted into the groove 25, it becomes difficult for the water flow to directly collide with the outer peripheral edge. Thereby, the protective sheet 3 for a display can be made more difficult to peel off.
图6是表示显示器用保护片3的变形例3的局部放大剖视图，并且是相当于图2所示的A部分的图。此外，在图6中，省略显示器1。在变形例3中，在安装盘2的表面2a形成的槽25具有：第1槽25a，其设置于显示部开口21的开口缘；以及第2槽25b，其在第1槽25a的外周侧形成且比第1槽25a形成得浅。FIG. 6 is a partially enlarged cross-sectional view showing Modification 3 of the protective sheet 3 for a display, and is a view corresponding to part A shown in FIG. 2 . In addition, in FIG. 6 , the display 1 is omitted. In modification 3, the groove 25 formed on the surface 2a of the mounting plate 2 has: a first groove 25a provided on the opening edge of the display portion opening 21; and a second groove 25b on the outer peripheral side of the first groove 25a. It is formed shallower than the first groove 25a.
另外，第2片材32在正视观察时与第1片材31重叠，并且伸出至外周侧。此处，通过将第1槽25a的深度设为等于第1片材31的厚度、第2片材32的厚度和双面胶带22、23的厚度之和，将第2槽25b的深度设为等于第2片材32的厚度和双面胶带23的厚度之和，从而如图6所示，第2片材32和安装盘2的表面2a成为同一个面。由此，使显示器用保护片3进一步难以剥落。另外，能够减少尘埃容易积存的凹凸部位，有助于对显示装置10进行设置的空间的清洁性的提高。Moreover, the 2nd sheet|seat 32 overlaps with the 1st sheet|seat 31 when viewed from the front, and protrudes to the outer peripheral side. Here, by setting the depth of the first groove 25a to be equal to the sum of the thickness of the first sheet 31, the thickness of the second sheet 32, and the thicknesses of the double-sided tapes 22, 23, the depth of the second groove 25b is set to be It is equal to the sum of the thickness of the second sheet 32 and the thickness of the double-sided tape 23, so as shown in FIG. 6, the second sheet 32 and the surface 2a of the mounting plate 2 become the same surface. This makes it more difficult for the protective sheet 3 for a display to peel off. In addition, it is possible to reduce unevenness where dust tends to accumulate, and contribute to improvement of the cleanliness of the space where the display device 10 is installed.
图7是表示显示器用保护片3的变形例4的局部放大剖视图，并且是相当于图2所示的A部分的图。此外，在图7中，省略显示器1。在变形例4中，通过双面胶带22将第1片材31粘附于以等于第1片材31的厚度和双面胶带22的厚度之和的深度形成的槽25的底面。由此，如图7所示，第1片材31与安装盘2的表面2a成为同一个面。由此，由于水流难以直接碰撞到显示器用保护片3的外周缘，因此显示器用保护片3进一步难以剥落。另外，能够减少尘埃容易积存的凹凸部位，有助于对显示装置10进行设置的空间的清洁性的提高。FIG. 7 is a partially enlarged cross-sectional view showing Modification 4 of the protective sheet 3 for a display, and is a view corresponding to part A shown in FIG. 2 . In addition, in FIG. 7 , the display 1 is omitted. In Modification 4, the first sheet 31 is adhered to the bottom surface of the groove 25 with a depth equal to the sum of the thickness of the first sheet 31 and the thickness of the double-sided tape 22 with the double-sided tape 22 . Thereby, as shown in FIG. 7, the 1st sheet|seat 31 becomes the same surface as the surface 2a of the mounting board 2. As shown in FIG. Thereby, since the water flow is hard to directly collide with the outer peripheral edge of the protective sheet 3 for a display, the protective sheet 3 for a display is further difficult to peel off. In addition, it is possible to reduce unevenness where dust tends to accumulate, and contribute to improvement of the cleanliness of the space where the display device 10 is installed.
图8是表示显示器用保护片3的变形例5的局部放大剖视图，并且是相当于图2所示的A部分的图。在变形例5中，以将覆盖中央区域3a的第1片材31的周围包围的方式设置第2片材32。即，在正视观察时不具有第1片材31和第2片材32重叠的区域。此外，与上述变形例1不同，第2片材32的内周缘与第1片材31的外周缘没有接合。因此，第1片材31的外周部通过双面胶带22直接粘附于安装盘2的表面2a，第2片材32通过双面胶带23直接粘附于安装盘2的表面2a。在这样的结构中，由于第1片材31的外周缘被第2片材32包围，因此水流变得难以直接碰撞到第1片材31的外周缘。由此，显示器用保护片3具备的第1片材31及第2片材32变得难以从安装盘2剥落。FIG. 8 is a partially enlarged cross-sectional view showing Modification 5 of the protective sheet 3 for a display, and is a view corresponding to part A shown in FIG. 2 . In Modification 5, the second sheet 32 is provided so as to surround the first sheet 31 covering the central region 3 a. That is, there is no region where the first sheet 31 and the second sheet 32 overlap when viewed from the front. In addition, unlike Modification 1 described above, the inner peripheral edge of the second sheet 32 is not joined to the outer peripheral edge of the first sheet 31 . Therefore, the outer peripheral portion of the first sheet 31 is directly adhered to the surface 2 a of the mounting plate 2 with the double-sided tape 22 , and the second sheet 32 is directly adhered to the surface 2 a of the mounting plate 2 with the double-sided tape 23 . In such a configuration, since the outer peripheral edge of the first sheet 31 is surrounded by the second sheet 32 , it becomes difficult for the water flow to directly collide with the outer peripheral edge of the first sheet 31 . Thereby, the 1st sheet material 31 and the 2nd sheet material 32 with which the protective sheet 3 for displays are equipped are hard to peel off from the mounting board 2. As shown in FIG.
实施方式2.Implementation mode 2.

Fig. 10 is a cross-sectional view taken along line X-X shown in Fig. 9 . In addition, the same code|symbol is attached|subjected to the same structure as Embodiment 1 mentioned above, and detailed description is abbreviate|omitted.
在本实施方式2涉及的显示装置11中，显示器用保护片13是横跨中央区域13a及外周区域13b而设置的，并且在外周区域13b形成从中央区域13a侧向外周区域13b的外周缘延伸的多个槽34。另外，外周区域13b通过双面胶带22粘附于安装盘2的表面2a。In the display device 11 according to Embodiment 2, the protective sheet 13 for a display is provided across the central region 13a and the outer peripheral region 13b, and is formed in the outer peripheral region 13b to extend from the central region 13a side to the outer peripheral edge of the outer peripheral region 13b. A plurality of grooves 34. In addition, the peripheral region 13b is adhered to the surface 2a of the mounting pad 2 by the double-sided tape 22 .
如上所述，通过在外周区域13b形成多个槽34，从而能够将外周区域13b的刚性设为比中央区域13a的刚性高，抑制显示器用保护片13从安装盘2剥落。As described above, by forming a plurality of grooves 34 in the outer peripheral region 13b, the rigidity of the outer peripheral region 13b can be made higher than that of the central region 13a, and the peeling of the display protection sheet 13 from the mounting board 2 can be suppressed.
以上的实施方式所示的结构表示的是本发明的内容的一个例子，还可以与其它的公知技术进行组合，在不脱离本发明的主旨的范围，也可以省略、变更结构的一部分。The configuration shown in the above embodiments is an example of the content of the present invention, and may be combined with other known techniques, and a part of the configuration may be omitted or changed without departing from the gist of the present invention.
