Abstract

The present application discloses a display panel, including several pixel units, each pixel unit has several sub-pixels, each sub-pixel has a main area and a sub-area; each sub-pixel has a sub-area located in the main area and the sub-area A pixel electrode, the pixel electrode includes a main body and a plurality of branches connected to the main body; one of the sub-pixels in each pixel unit has a shared electrode and a light-shielding layer, and the shared electrode is derived from the main body of this sub-pixel The area extends to the sub-area of ​​this sub-pixel, and the light-shielding layer is arranged on the main area and the sub-area of ​​this sub-pixel. This design releases the physical shading space of the red sub-pixel and green sub-pixel, and can achieve an increase of about 5% in the aperture ratio. If the width of the actual central dark stripe is considered, the increase will reach about 6.3%. The effective increase in the aperture ratio will promote Significant improvement in penetration.

Description

technical field [0001] The present application relates to the technical field of display panels, in particular to a display panel. Background technique [0002] With the gradual promotion of high-profile displays, major panel manufacturers are scrambling to deploy key display technologies such as high resolution and low color shift, and 3T technology and DBS (Data Line BM Less) technology have emerged one after another. 3T+&8domain (8 domains, 3 transistors) design has attracted widespread attention for its excellent color shift performance, making the 4 domains of the main (main) area and the 4 domains of the sub (sub) area in the same sub pixel The rotation angle of the liquid crystal molecules is different, thereby improving the color shift. [0003] Among them, the 3T technology is specifically that three TFT switches are controlled by the same gate line. When the gate is turned on, two of the TFTs charge the main area and the sub area of ​​the pixel electrode respectiv...
