技术领域technical field
本发明涉及显示技术领域，特别涉及一种显示屏、拼接显示屏及显示装置。The invention relates to the field of display technology, in particular to a display screen, a spliced display screen and a display device.
背景技术Background technique
随着TFT-LCD技术的飞速发展，大尺寸显示屏逐渐成为显示行业市场发展的需求。其中，利用平板显示屏进行拼接是实现大屏幕显示的一种主要方式。由于液晶屏设计和制作工艺方面的限制，LCD显示屏一般都具有黑色的周边设计，该周边部分包含了LCD面板的电路引线、封框胶、黑色矩阵等，是电子驱动和工艺制作不可缺少的空间部分。因此，利用LCD面板进行拼接显示时，较大的拼接缝隙会将图像隔断，破坏了拼接图像的观看性和连续性。通常，行业内采用B～B(Bezel～Bezel)或是A/A～A/A(ActiveArea～ActiveArea)值来定义拼接屏连接缝隙的大小。参考图1，为现有技术中拼接显示屏拼接方式示意图。通常，拼接屏最窄的B～B值为5.5mm或是5.3mm，其对应的A/A～A/A值为5.9mm或是5.6mm。With the rapid development of TFT-LCD technology, large-size display screens have gradually become the demand for market development in the display industry. Among them, splicing by using a flat-panel display screen is a main way to realize a large-screen display. Due to the limitations of LCD screen design and manufacturing process, LCD displays generally have a black peripheral design. The peripheral part includes the circuit leads of the LCD panel, sealing glue, black matrix, etc., which are indispensable for electronic drive and process production. space part. Therefore, when the LCD panel is used for splicing display, large splicing gaps will cut off the images, destroying the viewability and continuity of the spliced images. Usually, B~B (Bezel~Bezel) or A/A~A/A (ActiveArea~ActiveArea) values are used in the industry to define the size of the connection gap of the splicing screen. Referring to FIG. 1 , it is a schematic diagram of a splicing method of splicing display screens in the prior art. Usually, the narrowest B~B value of the splicing screen is 5.5mm or 5.3mm, and the corresponding A/A~A/A value is 5.9mm or 5.6mm.
现有拼接屏技术，为达到窄细化拼接缝隙，即缩小B～B或是A/A～A/A值，主要是通过细化每个拼接单元周边设计，比如，缩小电极绑定区域（PadArea），以及减小封框区域（SealingArea）。In the existing splicing screen technology, in order to achieve narrow and refined splicing gaps, that is, to reduce the value of B~B or A/A~A/A, it is mainly through refining the peripheral design of each splicing unit, for example, reducing the electrode binding area ( PadArea), and reduce the sealing area (SealingArea).
在实际生产中发现，现有拼接屏细化拼接缝存在如下几个问题：In actual production, it is found that the existing splicing screens have the following problems in refining the splicing seams:
（1）PadArea及SealingArea都以工艺极限值来设计，容易受到设备及工艺限制，难以实现进一步细化拼接连接缝隙的目的；(1) Both PadArea and SealingArea are designed with process limit values, which are easily limited by equipment and process, and it is difficult to further refine the splicing connection gap;
（2）PadArea及SealingArea缩小后，导致每个拼接单元后工序Bonding及封胶难度极大提高，拼接单元良率受到影响；(2) After PadArea and SealingArea are reduced, the difficulty of Bonding and sealing in the post-process Bonding and sealing of each splicing unit is greatly increased, and the yield of the splicing unit is affected;
（3）通过现有设备及工艺极限方式进行，拼接屏连接缝隙基本无法达到B～B<5.0mm。(3) Through the existing equipment and process limit method, the connection gap of the splicing screen basically cannot reach B～B<5.0mm.

The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.
实施例一Embodiment one
本发明提供一种显示屏，该显示屏包括有效显示区域和周边区域，所述周边区域的至少一侧表面设有呈凸起结构且能够使有效显示区域边缘的部分光线汇聚到周边区域的透镜。The present invention provides a display screen, which includes an effective display area and a peripheral area, at least one side surface of the peripheral area is provided with a lens having a convex structure and capable of converging part of the light at the edge of the effective display area to the peripheral area .

Wherein, the optically transparent material may be, for example, optical resin, acrylic or other optically transparent materials. The lens is pasted on the surface of the peripheral area with a transparent adhesive with strong adhesion. The width of the lens matches the width of the peripheral area.

其中一种方式为所有的透镜凸起结构大小相等，分布均匀，来自有效显示区域边缘的部分光线通过透镜的二次折射后，可以汇聚到周边区域上，这样有效地缩小了周边区域的暗区宽度。One of the methods is that all the convex structures of the lens are equal in size and evenly distributed. Part of the light from the edge of the effective display area can be converged to the surrounding area after passing through the double refraction of the lens, thus effectively reducing the dark area of the surrounding area. width.
另外一种方式为位于中间位置的凸起的高度大于分布其两侧的凸起的高度，所述位于两侧的凸起的高度顺次递减，由众多小凸起同样形成一个大的凸起结构，来自有效显示区域边缘的部分光线通过透镜的二次折射后，可以汇聚到周边区域上，这样有效地缩小了周边区域的暗区宽度。Another way is that the height of the protrusion located in the middle is greater than the height of the protrusions distributed on both sides, and the height of the protrusions located on both sides decreases successively, and a large protrusion is also formed by many small protrusions structure, part of the light from the edge of the effective display area can be converged to the peripheral area after passing through the double refraction of the lens, thus effectively reducing the width of the dark area in the peripheral area.
实施例二Embodiment two
本发明实施例提供一种拼接显示屏，该拼接显示屏由多个显示屏对接而成，An embodiment of the present invention provides a spliced display screen, which is formed by docking multiple display screens.
其中，至少一个显示屏为实施例一中所描述的显示屏，其余显示屏为现有技术的普通显示屏即可。当然，该拼接显示屏中的所有显示屏也可以均为实施例一中所描述的显示屏。实施例三Wherein, at least one display screen is the display screen described in Embodiment 1, and the rest of the display screens may be ordinary display screens in the prior art. Certainly, all the display screens in the spliced display screen may also be the display screens described in the first embodiment. Embodiment three
如图2所示，本实施例提供一种拼接显示屏，该拼接显示屏包括两个对接而成的显示屏，其中，该显示屏为普通显示屏即可，其包括有效显示区域1（图中标号1位于的空白位置）和周边区域2，当两个显示屏对接时，该两个显示屏中的周边区域2进行对接形成对接区域；As shown in Figure 2, this embodiment provides a spliced display screen, the spliced display screen includes two butt-connected display screens, wherein, the display screen can be an ordinary display screen, which includes an effective display area 1 (Fig. The blank position where the mark 1 is located) and the surrounding area 2, when the two display screens are docked, the peripheral area 2 in the two display screens is docked to form a docking area;
所述对接区域至少一侧表面设有呈凸起结构且能够使有效显示区域边缘的部分光线汇聚到对接区域的透镜3。At least one side surface of the docking area is provided with a lens 3 having a convex structure and capable of converging part of the light at the edge of the effective display area to the docking area.
具体来说，本实施例中的透镜3优选有光学透光材料制成。其中，光学透光材料例如可以为光学树脂、亚克力或其他光学透光材料。该透镜3采用具有强粘结性的透明粘剂粘贴在所述对接区域表面。该透镜3的宽度与对接区域的宽度相匹配。Specifically, the lens 3 in this embodiment is preferably made of an optically transparent material. Wherein, the optically transparent material may be, for example, optical resin, acrylic or other optically transparent materials. The lens 3 is pasted on the surface of the docking area with a strong adhesive transparent adhesive. The width of the lens 3 matches the width of the abutment area.
由于透镜3为细条状结构，其位于对接而成显示屏的对接区域上，其重量将非常微小，因此，不存在脱落和固定不牢固的问题。Since the lens 3 is a strip-shaped structure, it is located on the butt joint area of the butt joint display screen, and its weight will be very small, so there is no problem of falling off or loose fixation.
其中，该显示屏中的周边区域包括边框4，该透镜粘贴在边框4上，在此结构下，该透镜3的凸起结构为单一凸起即可，该凸起结构为柱状，所述柱状的顶部为弧形。Wherein, the peripheral area in the display screen includes a frame 4, and the lens is pasted on the frame 4. Under this structure, the protrusion structure of the lens 3 can be a single protrusion, and the protrusion structure is columnar, and the columnar The top is curved.
来自有效显示区域边缘的部分光线通过透镜的二次折射后，可以汇聚到对接区域上，这样有效地缩小了对接区域的暗区宽度，进而在视觉上进一步细化拼接屏拼接位置的缝隙，从而达到在窄细工艺的基础上进一步缩小A/A～A/A的距离，实现拼接屏的超细拼接。Part of the light from the edge of the effective display area can be converged on the docking area after passing through the double refraction of the lens, which effectively reduces the width of the dark area in the docking area, and further refines the gap in the splicing position of the splicing screen visually, thereby On the basis of narrow technology, the distance from A/A to A/A can be further reduced, and the ultra-fine splicing of splicing screens can be realized.
设置在A/A～A/A>4.6mm的情况下，采用2块55inch的显示屏进行拼接为例，参考图3，为现有技术中拼接显示屏在拼接缝隙处的暗区图；图4为现有拼接显示亮度曲线图。其中，为了强化对比结果，将光源的光通量设定为原来的8倍，即原来对应的亮度为400cd/m2～450cd/m2，那么强化后的亮度为3200cd/m2～3600cd/m2。从图中可以看出，拼接区域存在暗区，且暗区较宽。In the case of setting A/A～A/A>4.6mm, take two 55-inch display screens for splicing as an example, refer to Figure 3, which is a diagram of the dark area at the splicing gap of the splicing display screen in the prior art; 4Display the brightness graph for the existing tile. Among them, in order to strengthen the contrast result, the luminous flux of the light source is set to 8 times the original, that is, the original corresponding brightness is 400cd/m2 ~ 450cd/m2 , then the enhanced brightness is 3200cd/m2 ~ 3600cd/m2 . It can be seen from the figure that there is a dark area in the stitching area, and the dark area is wide.
参考图5和图6，为在相同条件下，增设了透镜3后拼接显示屏在对接区域的暗区和亮度曲线图，通过与图2和图3对比，本实施例中的对接区域的暗区明显小于现有技术中的暗区，该拼接显示屏的亮度得以提升。Referring to Fig. 5 and Fig. 6, under the same conditions, the dark area and brightness curve of the spliced display screen in the docking area after adding the lens 3, by comparing with Fig. 2 and Fig. 3, the dark area of the docking area in this embodiment The area is obviously smaller than the dark area in the prior art, and the brightness of the spliced display screen is improved.
实施例四Embodiment Four
本实施例与实施例三存在的区别在于，本实施例中显示屏的周边区域不包括边框，该透镜3粘贴在周边区域除边框的其他区域上，在此结构下，该透镜3包括复数个连续的凸起。其中，该凸起结构具体包括两种方式：The difference between this embodiment and the third embodiment is that the peripheral area of the display screen in this embodiment does not include a frame, and the lens 3 is pasted on other areas of the peripheral area except the frame. Under this structure, the lens 3 includes a plurality of Continuous bumps. Among them, the raised structure specifically includes two ways:
参考图7，其中一种方式为所有的透镜3凸起结构大小相等，分布均匀，来自有效显示区域边缘的部分光线通过透镜的二次折射后，可以汇聚到周边区域上，这样有效地缩小了周边区域的暗区宽度。Referring to Figure 7, one way is that all the convex structures of the lens 3 are equal in size and evenly distributed, and part of the light from the edge of the effective display area can be converged to the surrounding area after passing through the double refraction of the lens, thus effectively reducing the The width of the dark zone in the surrounding area.
参考图8，另外一种方式为位于中间位置的凸起的高度大于分布其两侧的凸起的高度，所述位于两侧的凸起的高度顺次递减，由众多小凸起同样形成一个大的凸起结构，将来自有效显示区域边缘的部分光线通过透镜的二次折射后，可以汇聚到周边区域上，这样有效地缩小了周边区域的暗区宽度。Referring to Fig. 8, another way is that the height of the protrusion located in the middle is greater than the height of the protrusions distributed on both sides, and the heights of the protrusions located on both sides decrease successively, and a large number of small protrusions also form a The large convex structure can gather part of the light from the edge of the effective display area to the peripheral area after being refracted twice by the lens, thus effectively reducing the width of the dark area in the peripheral area.
来自有效显示区域边缘的部分光线通过透镜的二次折射后，可以汇聚到对接区域上，这样有效地缩小了对接区域的暗区宽度，进而在视觉上进一步细化拼接屏拼接位置的缝隙，从而达到在窄细工艺的基础上进一步缩小A/A～A/A的距离，实现拼接屏的超细拼接。Part of the light from the edge of the effective display area can be converged on the docking area after passing through the double refraction of the lens, which effectively reduces the width of the dark area in the docking area, and further refines the gap in the splicing position of the splicing screen visually, thereby On the basis of narrow technology, the distance from A/A to A/A can be further reduced, and the ultra-fine splicing of splicing screens can be realized.
