目前，由于环境光的影响，使得在环境光较强的情况下，出现用户无法看清显示画面的情况，严重影响用户的视觉体验。At present, due to the influence of ambient light, when the ambient light is strong, the user cannot see the display screen clearly, which seriously affects the visual experience of the user.
现有技术中为了实现显示亮度随环境光明暗的自动调节，往往是采用独立的光线感应器探测环境光强，然后根据反馈的环境光强调节整个显示亮度。In the prior art, in order to realize the automatic adjustment of the display brightness according to the ambient light and darkness, an independent light sensor is often used to detect the ambient light intensity, and then the entire display brightness is adjusted according to the feedback of the ambient light intensity.
然而，在实际使用中，若光线感应器被挡住，则根据环境光的明暗调节显示亮度就无法实现，并且反应慢、响应时间长。However, in actual use, if the light sensor is blocked, it is impossible to adjust the display brightness according to the brightness of the ambient light, and the response is slow and the response time is long.

其中，阳极201可以为透明或不透明。当阳极201为透明时，可采用透明导电材料，例如ITO(氧化铟锡)、IZO(氧化铟锌)等制成；当阳极201为不透明时，可采用透明导电层/不透明金属层/透明导电层三层结构，例如ITO导电层/Ag导电层/ITO导电层三层结构。Wherein, the anode 201 can be transparent or opaque. When the anode 201 is transparent, it can be made of a transparent conductive material, such as ITO (indium tin oxide), IZO (indium zinc oxide), etc.; when the anode 201 is opaque, a transparent conductive layer/opaque metal layer/transparent conductive layer can be used Three-layer structure, such as ITO conductive layer/Ag conductive layer/ITO conductive layer three-layer structure.
阴极202可以为半透明或不透明。不管阴极202为半透明或不透明，均采用金属材料制成，通过控制阴极202的厚度，可控制其半透明或不透明。Cathode 202 can be translucent or opaque. Regardless of whether the cathode 202 is translucent or opaque, it is made of metal material. By controlling the thickness of the cathode 202, its translucence or opacity can be controlled.
根据阳极201、阴极202的透明与否，该OLED元件20可进行底发光、顶发光和双面发光，具体可根据需要进行设置，在此不做限定。Depending on whether the anode 201 and the cathode 202 are transparent, the OLED element 20 can perform bottom emission, top emission and double-sided emission, which can be set according to needs, and are not limited here.
需要说明的是，第一，由于OLED显示器可分为AMOLED(Active-matrixOrganicLightEmittingDiode，有源矩阵型有机发光二极管)显示器和PMOLED(Passivematrixorganiclightemittingdiode，被动式有机发光二极管)显示器，因此驱动部件的具体结构可根据OLED显示器的类型而定，具体在此不做限定，只要能驱动OLED元件20发光即可。It should be noted that, first, since OLED displays can be divided into AMOLED (Active-matrix Organic Light Emitting Diode, active matrix organic light emitting diode) displays and PMOLED (Passive matrix organic light emitting diode, passive organic light emitting diode) displays, the specific structure of the driving part can be based on the OLED It depends on the type of the display, and there is no specific limitation here, as long as the OLED element 20 can be driven to emit light.
其中，不管光电转换部件30是否有电能产生，上述驱动部件都可以驱动OLED元件20发光，使OLED显示器正常显示。Wherein, no matter whether the photoelectric conversion unit 30 generates electric energy or not, the driving unit can drive the OLED element 20 to emit light, so that the OLED display can display normally.
具体的，当光电转换部件30没有电能产生，即无外界环境光照射时，OLED元件20完全依靠驱动部件提供至其阳极201和阴极202之间的电压差发光而进行正常显示。当光电转换部件30有电能产生，即有外界环境光照射时，驱动部件仍然向OLED元件20提供其正常显示的电压，与此同时，光电转换部件30产生的电能也以电压形式提供至OLED元件20，此时，提供至OLED元件20的阳极201和阴极202之间的电压差相较于只有驱动部件提供至阳极201和阴极202之间的电压差有所增加。Specifically, when the photoelectric conversion component 30 has no power generation, that is, when there is no external ambient light, the OLED element 20 emits light completely depending on the voltage difference between the anode 201 and the cathode 202 provided by the driving component to perform normal display. When the photoelectric conversion part 30 has electric energy generated, that is, when there is external ambient light, the driving part still provides the normal display voltage to the OLED element 20, and at the same time, the electric energy generated by the photoelectric conversion part 30 is also provided to the OLED element in the form of voltage. 20. At this time, the voltage difference provided to the anode 201 and the cathode 202 of the OLED element 20 is increased compared to the voltage difference provided to the anode 201 and the cathode 202 by only the driving component.
第二，对于光电转换部件30，以能将外界环境光的光能转换为电能为准。Second, for the photoelectric conversion component 30 , it shall prevail that it can convert light energy of ambient light into electrical energy.
此外，不对光电转换部件30的设置位置进行限定，只要能将其产生的电能以电压形式提供至OLED元件20，并能叠加在驱动部件提供至阳极201和阴极202之间的电压上为准。In addition, the installation position of the photoelectric conversion component 30 is not limited, as long as the electric energy generated by it can be supplied to the OLED element 20 in the form of voltage, and can be superimposed on the voltage provided between the anode 201 and the cathode 202 by the driving component.
本实用新型实施例提供了一种OLED显示器，通过设置驱动部件，当不管是否有外界环境光照射时，都可以驱动OLED元件20发光而进行正常显示；在此基础上，通过设置光电转换部件30，当有外界环境光照射时，随着光照强度的增加，光电转换部件30产生的电能也相应增加，提供至OLED元件20的阳极201和阴极202之间的压差也相应增大，从而使得OLED元件20的发光亮度随着环境光照强度的增加而提升，因而可实现显示亮度随环境光强度变化的自动调节功能，避免了现有技术中单一光线感应器被遮挡而无法响应环境光强变化的情况。其中，由于光电转换部件30产生的电能以电压形式直接作用在OLED元件20上，因此显示亮度随环境光强度变化的灵敏度较高。The embodiment of the present invention provides an OLED display. By setting the driving part, the OLED element 20 can be driven to emit light and perform normal display regardless of whether there is external ambient light; on this basis, by setting the photoelectric conversion part 30 , when there is external ambient light, as the light intensity increases, the electric energy generated by the photoelectric conversion component 30 also increases correspondingly, and the voltage difference between the anode 201 and the cathode 202 supplied to the OLED element 20 also increases correspondingly, so that The luminance of the OLED element 20 increases with the increase of the ambient light intensity, so that the automatic adjustment function of the display brightness with the change of the ambient light intensity can be realized, and the single light sensor in the prior art is blocked and cannot respond to the change of the ambient light intensity. Case. Wherein, since the electric energy generated by the photoelectric conversion component 30 acts directly on the OLED element 20 in the form of voltage, the display brightness has a high sensitivity to changes in ambient light intensity.
优选的，如图2所示，光电转换部件30与OLED元件20一一对应。Preferably, as shown in FIG. 2 , the photoelectric conversion components 30 correspond to the OLED elements 20 one by one.
即，每个OLED元件20都具有显示亮度随环境光强度变化的自动调节功能，因而可以实现显示亮度随环境光强度变化的局部、精细调节，调节精度更高。That is, each OLED element 20 has an automatic adjustment function of display brightness changing with ambient light intensity, so local and fine adjustment of display brightness with ambient light intensity can be realized with higher adjustment accuracy.
进一步优选的，如图4所示，为光电转换部件30向OLED元件20供电的等效电路图，其中OLED元件20的阳极201与驱动部件中的第一电压端V1相连，阴极202与驱动部件中的第二电压端V2相连。其中，第二电压端V2例如可以接地。Further preferably, as shown in FIG. 4 , it is an equivalent circuit diagram of the photoelectric conversion component 30 supplying power to the OLED element 20, wherein the anode 201 of the OLED element 20 is connected to the first voltage terminal V1 in the driving component, and the cathode 202 is connected to the first voltage terminal V1 in the driving component. connected to the second voltage terminal V2. Wherein, the second voltage terminal V2 may be grounded, for example.

本实用新型实施例中，通过第一电容302可将太阳能电池301产生的电能以电压形式进行存储，通过整流二极管303可将太阳能电池301的正极的电压加载在OLED元件20的阳极201。当照射在太阳能电池301上的外界环境光强度发生变化时，太阳能电池301正极上所产生的电压会随之发生变化，使得OLED元件20的亮度也会随之发生变化；当外界环境光停止照射在太阳能电池301上时，太阳能电池301正极上的电压消失，使得OLED元件20的亮度将回到没有外界环境光照射的状态，从而实现显示亮度随环境光强度变化的自动调节功能。In the embodiment of the present invention, the electric energy generated by the solar cell 301 can be stored in the form of voltage through the first capacitor 302 , and the positive voltage of the solar cell 301 can be applied to the anode 201 of the OLED element 20 through the rectifier diode 303 . When the intensity of external ambient light irradiated on the solar cell 301 changes, the voltage generated on the positive electrode of the solar cell 301 will change accordingly, so that the brightness of the OLED element 20 will also change accordingly; When it is on the solar cell 301, the voltage on the positive electrode of the solar cell 301 disappears, so that the brightness of the OLED element 20 will return to the state without external ambient light, thereby realizing the automatic adjustment function of the display brightness changing with the ambient light intensity.
进一步地，由于PMOLED应用在大尺寸显示器时，有其不足的一面，因此优选采用AMOLED。基于此，如图5所示，驱动部件还可以包括设置在每个子像素区域1的开关晶体管401、驱动晶体管402和第二电容403。Furthermore, since PMOLED has its shortcomings when applied to large-size displays, it is preferable to use AMOLED. Based on this, as shown in FIG. 5 , the driving component may further include a switching transistor 401 , a driving transistor 402 and a second capacitor 403 disposed in each sub-pixel region 1 .
其中，开关晶体管401的栅极与栅线SL相连，第一极与数据线DL相连，第二极与驱动晶体管402的栅极相连。Wherein, the gate of the switch transistor 401 is connected to the gate line SL, the first pole is connected to the data line DL, and the second pole is connected to the gate of the driving transistor 402 .
驱动晶体管402的第一极与第一电压端V1相连，第二极与整流二极管303的正极相连。The first pole of the driving transistor 402 is connected to the first voltage terminal V1 , and the second pole is connected to the anode of the rectifier diode 303 .
第二电容403的一端与开关晶体管401的第二极相连，另一端与整流二极管303的负极相连。One end of the second capacitor 403 is connected to the second pole of the switching transistor 401 , and the other end is connected to the cathode of the rectifier diode 303 .
