Description

有机发光二极管显示器 The organic light emitting diode display

【技术领域】 TECHNICAL FIELD

[0001] 本发明是有关于一种有机发光二极管显示器,且特别是有关于一种能改善由电源电压降(IR-drop)现象所导致的像素亮度不均勻问题的有机发光二极管显示器。 [0001] The present invention relates to an organic light emitting diode display, and more particularly relates to an organic light emitting diode display can improve the problem of uneven brightness of pixels by the power supply voltage drop (IR-drop) caused by the phenomenon.

【背景技术】 【Background technique】

[0002] 有机发光二极管(Organic Light Emitting Diode,0LED)面板是以有机发光二极管来作为发光组件。 [0002] The organic light emitting diode (Organic Light Emitting Diode, 0LED) panel is an organic light emitting diode as a light emitting component. 而有机发光二极管乃是一种由电流来进行驱动的组件,其发光亮度会随着通过有机发光二极管的电流而改变。 And thus an organic light emitting diode to be driven by the current components, the emission brightness as the current through the organic light emitting diode is changed. 因此,如何精准地控制通过有机发光二极管的电流遂成为有机电激发光面板发展中的重要课题。 Therefore, how to accurately control the current through the organic light emitting diode organic electroluminescent became an important issue in the development of the faceplate.

[0003] 请参照图1,其为现有的有机发光二极管显示器的示意图。 [0003] Referring to FIG 1, which is a schematic view of a conventional organic light emitting diode display. 此有机发光二极管显示器100包括有扫描驱动电路110、数据驱动电路120、电源电压供应电路130与有机发光二极管显示面板140。 The organic light emitting diode display 100 includes a scan driving circuit 110, a data driving circuit 120, circuit 130 supplies a power supply voltage of the organic light emitting diode display panel 140. 而有机发光二极管显示面板140又包括有多条扫描线(如标示142所示)、多条数据线(如标示144所示)、导线146与多个像素(如标示148所示)。 The organic light emitting diode display panel 140 further comprises a plurality of scanning lines (indicated as 142 shown), a plurality of data lines (shown as labeled 144), wires 146 and a plurality of pixels (shown as labeled 148). 每一像素148由晶体管148-1、晶体管148-2、电容148-3与有机发光二极管148-4所组成,而图中所示的OVSS为参考电源。 Each pixel 148 of a transistor 148-1, transistor 148-2, and capacitors 148-3 148-4 composed of an organic light emitting diode, and FIG OVSS the reference power. 以上所述构件的连接关系已在图1中展示,在此便不再赘述。 Connection relationship of the above member has been shown in FIG. 1, not repeated here. 此外,这些像素148以矩阵的方式排列,以形成有机发光二极管显示面板140的显示区。 Further, the pixels 148 are arranged in a matrix to form a display area of ​​the organic light emitting diode display panel 140. 而此显示区即是用以显示图像及文字。 This display area and that is configured to display images and text.

[0004] 在图1所示的架构中,每一像素148中的晶体管148-2皆透过导线146电性耦接电源电压供应电路130所提供的电源电压0VDD,以便获得一显示电位(如标示0VDD'所示), 且每一像素148中的有机发光二极管148-4的阴极皆电性耦接参考电源0VSS,以便获得一参考电位。 [0004] In the architecture shown in Figure 1, each pixel 148 of the transistor 148-2 are coupled to the power supply voltage of the voltage supply circuit 130 0VDD provided through electrical conductors 146, so as to obtain a display potential (e.g. Flag 0VDD 'shown), and the organic light emitting diode in each pixel 148 of the cathode 148-4 are electrically coupled to the reference power 0VSS, so as to obtain a reference potential. 而显示电位0VDD'与参考电位的电位差将会与数据线144所传送的数据电压共同影响通过有机发光二极管148-4的电流大小,藉此控制有机发光二极管148-4的亮度。 Displaying potential 0VDD 'potential difference between the common reference potential will affect the magnitude of the current through the organic light emitting diode 148-4 and the data voltage transmitted by the data line 144, thereby controlling the luminance of the organic light emitting diode 148-4.

[0005] 一般而言,参考电位乃是一个定值,然而各个像素148所接收的显示电位0VDD'的大小,却会随着像素位置的不同而有所改变。 [0005] In general, the potential but a reference value, however, the respective pixels 148 to display the received potential 0VDD 'size, but with different pixel positions may be changed. 也就是说,电源电压供应电路130所提供的电流透过不同的电流传递路径而传递至不同的像素148,而由于不同的电流传递路径长度会产生不同的电压降(此即所谓的顶drop),因而导致这些像素148所接收到的显示电位OVDD'的大小有所不同。 That is, current of the power supply voltage provided by circuit 130 is transmitted through a transmission path different from the current 148 to a different pixel, but due to the different transmission path lengths of the current will produce a different voltage drop (namely the so-called top drop) , resulting in the pixels 148 to display the received potential OVDD 'of different sizes.

[0006] 承上述,由于这些像素148所接收到的显示电位0VDD'的大小有所不同,造成通过这些有机发光二极管148-4的电流大小互不相同,进而使得这些有机发光二极管148-4的亮度不均勻。 [0006] Bearing the above, since the size of the potential of the display pixels 148 received 0VDD 'are different, by causing the organic light emitting diode 148-4 of mutually different current magnitude, thereby making the organic light emitting diodes 148-4 uneven brightness. 换句话说,上述的电源电压降现象就是导致这些像素148的亮度不均勻的主因。 In other words, the above phenomenon is the supply voltage drops result in uneven brightness of these pixels 148 main cause.

【具体实施方式】 【Detailed ways】

[0038] 第一实施例: [0038] First Embodiment:

[0039] 图2为依照本发明一实施例的有机发光二极管显示器的示意图。 [0039] FIG. 2 is a schematic view of an organic light emitting diode display in accordance with an embodiment of the present invention. 此图2所示的有机发光二极管显示器200仅绘示与图1所示的有机发光二极管显示器100的相异的处,而其它相同的处则予以省略,以避免赘述与混淆本发明的重点。 The organic light emitting diode display shown in this schematic shown in FIG 2200 shown only in FIG. 1 with an organic light emitting diode display 100 at a different, and the other at the same will be omitted to avoid redundancy and the focus of the present invention obscure.

[0040] 如图2所示,此有机发光二极管显示器200主要包括了有机发光二极管显示面板202、导线210、导线212与电源电压供应电路220。 [0040] As shown in FIG 2, the organic light emitting diode display 200 includes an organic light emitting diode display panel 202, the wire 210, the wire 212 and the power source voltage supply circuit 220. 有机发光二极管显示面板202具有由多个像素(未绘示)所形成的显示区204,且显示区204划分为子显示区206与子显示区208。 The organic light emitting diode display panel 202 has a display area 204 by a plurality of pixels (not shown) is formed, and the sub display area 204 is divided into a display area 206 and the sub display area 208. 在此例中,子显示区206的面积大小与子显示区208的面积大小为相同。 In this embodiment, the sub display area 206 is an area the size of the sub-region 208 of the display area size is the same. 然而,这二个子显示区的面积大小亦可为不同。 However, these two sub-display area size of the region may also be different.

[0041] 此外,上述的导线210设置在有机发光二极管显示面板202上且位于显示区206外,且导线210的第一端210-1电性耦接子显示区206内的每一像素。 [0041] Further, the wire 210 disposed on the organic light emitting diode display and the display area 206 on the outer panel 202, and a first end of the conductor 210 is electrically coupled to 210-1 of each pixel in the sub display area 206. 而导线212亦设置在有机发光二极管显示面板202上且位于显示区204外,且导线212的第一端212-1电性耦接子显示区208内的每一像素。 The conductor 212 is also provided an organic light emitting diode display and the display area 204 on the outer panel 202, and a first end of the conductor 212 is electrically coupled to 212-1 of each pixel in the sub display area 208. 由于布线路径的不同,导线212的布线长度大于导线210 的布线长度,使得导线212的阻值较导线210的阻值来得大。 Due to different wiring path, a wiring length of the wire 212 is greater than the length of the wiring conductor 210, such that the resistance wire 212 is far greater than the resistance of the wires 210.

[0042] 至于电源电压供应电路220,其电性耦接导线210的第二端210-2与导线212的第二端212-2,用以分别提供电源电压OVDDl与0VDD2至导线210的第二端210-2与导线212 的第二端212-2。 [0042] As the power source voltage supply circuit 220, which is electrically coupled to the second end of the wire 210 and the wire 212 210-2 second end 212-2, respectively, for providing a supply voltage to the wires 210 OVDDl and second 0VDD2 end 210-2 and a second end of the wire 212 212-2. 其中,电源电压0VDD2较电源电压OVDDl来得大,使得导线212的第一端212-1的电压大小(即V2')与导线210的第一端210-1的电压大小(即VI')实质上相同。 Wherein the power supply voltage 0VDD2 OVDDl far greater than the supply voltage, so that the size of the first end of the conductor voltage 212-1 (i.e., V2 ') 212 and the conductor voltage magnitude (i.e., a first end of the VI 210 210-1') is substantially the same. 以下将针对电压的调整方式来进行举例。 The following example will be made for the voltage adjusting mode.

[0043] 假设导线210的第二端210-2的电压大小为VI,而导线212的第二端212_2的电压大小为V2,并假设导线212的阻值为R2,且通过导线212的电流大小为12,那么导线212 的第一端212-1的电压大小(即V2' )可由下列式⑴来表示: [0043] Suppose the size of the wires 210 a voltage to a second terminal 210-2 VI, and the magnitude of the voltage of the second end of the wire 212 212_2 is V2, and assuming that the resistance wire 212 is R2, and the current through the conductor 212 12, the first end of the wire 212 212-1 magnitude voltage (i.e., V2 ') represented by the following formula ⑴:

[0044] V2' = V2-I2XR2 ......(1) [0044] V2 '= V2-I2XR2 ...... (1)

[0045] 因此,只要调整电源电压0VDD2的大小,使得导线212的第二端212_2的电压大小(即V2)也随的调整,直到导线212的第一端212-1的电压大小(即V2')与导线210的第一端210-1的电压大小(即VI')实质上相同为止。 [0045] Thus, as long as the supply voltage to adjust the size 0VDD2, 212 such that the wire size of the second voltage terminal 212_2 (i.e., V2) also with adjustments until the magnitude of the voltage lead wire 212 of the first end 212-1 (i.e., V2 ' ) and the magnitude of the voltage of the first lead terminal 210 210-1 (i.e., VI ') are substantially the same so far.
