Description

display panel

technical field

The present invention relates to a display panel, in particular to a display panel with sub-pixels having a specific polarity arrangement.

Background technique

Generally speaking, liquid crystal display panels have the advantages of light weight, low power consumption and low radiation, etc. Therefore, liquid crystal display panels have been widely used in various portable information products on the market, such as notebook computers (notebooks) and personal digital assistants. (personal digital assistant, PDA) and other commodities. When driving the liquid crystal display panel, because the liquid crystal molecules in it are fixed at an angle for too long, it will cause the liquid crystal molecules to generate deformation inertia, so that the liquid crystal display panel cannot change the screen. Therefore, in order to avoid reducing the display quality of the liquid crystal display panel, generally Use the polarity inversion driving method.

Generally, polarity inversion driving methods can be divided into frame inversion, row inversion, column inversion and dot inversion. Please refer to FIG. 1 . FIG. 1 is a schematic diagram illustrating a polarity arrangement of sub-pixels of a liquid crystal display panel driven by a conventional row inversion driving method. As shown in FIG. 1 , a known liquid crystal display panel 10 includes a plurality of sub-pixels 12 arranged in a matrix, and the polarity of the sub-pixels 12 in the same column is arranged in a sequence of positive polarity 14 and negative polarity 16 alternately, and Sub-pixels in the same row have the same polarity. In addition, the sub-pixels in each row are sub-pixels displaying red (R), green (G) and blue (B) respectively in sequence, and a red sub-pixel, an adjacent green sub-pixel and an adjacent blue sub-pixel The sub-pixels constitute a pixel 18 . In the next display frame, the polarity of each sub-pixel 12 will be switched to the opposite polarity, that is, the original positive polarity will be switched to negative polarity, and the negative polarity will be switched to positive polarity, so as to prevent the liquid crystal molecules from being fixed at the same angle for too long produce deformation inertia.

However, some of the pixels of the liquid crystal display panel are turned off during testing, so that the pixels in the same column display an alternately bright and dark image, and the pixels in the same row also display an alternate bright and dark image, so that the displayed image appears white. In this driving mode, both the turned-on red sub-pixels and the blue sub-pixels in the first row have positive polarity, and the turned-on green sub-pixels in the first row have negative polarity. Since the polarity of the sub-pixel is determined by the voltage of the pixel electrode of each sub-pixel compared with the common voltage, when the voltage of the pixel electrode is greater than the common voltage, the polarity of the sub-pixel is positive, and the voltage of the pixel electrode is high potential. On the contrary, the polarity of the sub-pixel is negative, and the voltage of the pixel electrode is a low potential. Therefore, when the number of sub-pixels with positive polarity is more than that of sub-pixels with negative polarity, it means that the pixel electrodes of more sub-pixels have a high potential voltage. In this case, the magnitude of the common voltage is easily affected by the voltage of the pixel electrode, and the voltage shifts to a high potential, so that the voltage difference between the driving red sub-pixel and the blue sub-pixel becomes smaller, and the voltage difference between driving the green sub-pixel becomes smaller. Increase. Further, the gray scale displayed by the red sub-pixel and the blue sub-pixel is relatively low, while the gray scale displayed by the green sub-pixel is relatively high, so the liquid crystal display panel may easily produce a greenish image during testing.

In order to prevent the liquid crystal display panel from producing a greenish image during testing, a method of using an inverter to change the polarity arrangement of the sub-pixels is proposed. Please refer to FIG. 2 . FIG. 2 is a polarity arrangement pattern of a conventional liquid crystal display panel using inverters to change the polarity of each sub-pixel. As shown in Figure 2, the data line driving circuit 22 of the liquid crystal display panel 20 includes an inverter 24, a first driving circuit 26 and a second driving circuit 28, and one terminal of the inverter 24 is coupled to the first The driving circuit 26 , and the other terminal is coupled to the second driving circuit 28 . The inverter 24 is used to invert the polarity of the display data signal input to the first driving circuit 26 and the display data signal input to the second driving circuit 28 . Therefore, in the same column, the red sub-pixels 30 of the first row and the red sub-pixels 30 of the seventh row have opposite polarities. By analogy, the green sub-pixels 32 in the second row and the green sub-pixels 32 in the eighth row, and the blue sub-pixels 34 in the third row and the blue sub-pixels 34 in the ninth row have opposite polarities. In this way, among all turned-on sub-pixels, the number of sub-pixels with positive polarity is the same as the number of sub-pixels with negative polarity, so that the common voltage will not be shifted.

However, in order to change the polarity of the sub-pixels, the conventional liquid crystal display panel needs to divide the pixel into two parts, one part is connected to a first driving circuit, and the other part is connected to a second driving circuit, and an inverter is coupled to the first driving circuit. The first driving circuit and the second driving circuit make the polarity provided by the first driving circuit opposite to that provided by the second driving circuit. Therefore, additionally adding an inverter in the liquid crystal display panel will increase the cost and increase the complexity of the data driving circuit. Moreover, generally, the driving chip used to control the liquid crystal display panel has an inverter and is located outside the liquid crystal display panel, so placing the inverter in the liquid crystal display panel will further limit the design of the driving chip.
