Description
Technical Field
The application relates to the technical field of display, in particular to a display panel.
Background
The Image Sticking (IS) IS a phenomenon that when the lcd displays the same picture for a long time and then switches the picture to the next picture, the original picture IS left in the next picture.
The CF com voltage when the sub-pixels are at 127 gray levels and the electrode voltages of the positive and negative frame sub-pixels are completely symmetrical with respect to the CF com is generally referred to as Best Vcom (BV).
In order to improve the display effect of the LCD panel under a large viewing angle, 8domain pixels are often used in the industry in combination with 3T plus design, and each sub-pixel of the 8domain pixels can be divided into a main pixel and a sub-pixel. Fig. 1 is an equivalent circuit diagram of each sub-pixel of an 8-domain pixel, wherein the voltage of the sub-pixel is released to the common electrode, thereby achieving an 8-domain display effect.
As shown in fig. 2, in the actual design and debugging process, the main pixel 1111 and the sub-pixel 1112 share the same CF COM electrode 101 (i.e. CF ITO full-face design). IS more likely to occur than 4domain pixel and 8domain pixel, but the reason for this IS that BV difference between the main pixel 1111 and the sub-pixel 1112 cannot satisfy the main pixel 1111 and the sub-pixel 1112 at the same time due to the set voltage of CF com, which leads to high IS. To reduce the IS risk, the 8domain design usually needs to increase the storage capacitance of the sub-pixel to reduce the BV difference between the main pixel and the sub-pixel, but the improvement IS limited, and the aperture ratio and the charging ratio are decreased, resulting in the transmittance loss.
Therefore, a new display panel is required to solve the above problems.
