Display panel with high display quality

Abstract

The invention provides a display panel with high display quality. The display panel comprises a plurality of double-gate pixel units which are connected with one another through data lines, scanning lines and common electrode lines, wherein each double-gate pixel unit comprises a first pixel and a second pixel, which are respectively connected with a first scanning line and a second scanning line and share one common electrode line and one data line; the first scanning line and the second scanning line are arranged on two opposite sides of the common electrode line; the first pixel and the second pixel are positioned on two opposite sides of the first scanning line and the second scanning line; the data line transmits data signals to the pixels; and the scanning line controls the pixels to receive the data signals. The aperture opening ratio of the pixels of the display panel can be improved, and the probability in short-circuiting of the scanning lines and the common electrode lines is reduced.

Description

【Technical field】 [0001] The present invention relates to a display panel, in particular to a display panel with high display quality. 【Background technique】 [0002] see figure 1 , in a traditional active matrix liquid crystal display (LCD), each pixel of its single-gate circuit structure has a thin-film transistor (TFT) 10, its gate is connected to the scanning line 12 in the horizontal direction, and its source is connected to the vertical scanning line. The drains of the data lines 14 in the direction are connected to the pixel electrodes, and the thin film transistors 10 in adjacent rows are respectively connected to the data lines 14 . [0003] The basic operation of this traditional circuit architecture is introduced below. On the same scanning line 12 in the horizontal direction, the gates of all thin film transistors 10 are connected together, so the applied voltage is linked. If a sufficiently large positive voltage is applied to the scanning line, all the thin f...

Problems solved by technology

[0005] But for the technology provided above, it is observed from the circuit layout, such as image 3 As shown, the scanning lines 20 and the common electrode lines 22 belong to the same metal layer and are very close to each other. Therefore, if particles accidentally fall into the panel during the manufacturing process, it is easy to cause the scanning lines 20 and the common electrode lines to be separated after the process is completed. Line 22 is short-circuited, which in turn leads to problems such as horizontal dark lines or bright lines on the panel display. In addition, because the two electrode layers 24 on the adjacent scanning line 20 and the adjacent data line 18 are respectively two The pixel display area of ​​each pixel, and the common electrode line 22 occupies the area of ​​the light-transmitting area of ​​the electrode layer 24, so that the light-transmitting area of ​​the electrode layer 24 minus the metal layer forming the common electrode line 22 becomes less, and then makes the entire panel less. loss of opening ratio
