Problems solved by technology

[0003] However, existing large-size display screens such as 75-inch 8K ADS TV products have serious light leakage along the direction of the data line, so it is difficult to achieve a transmittance of more than 50%.

Embodiment Construction

[0044] In order to make the above objects, features and advantages of the present invention more comprehensible, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0045] The inventors found that the main reason affecting the low aperture ratio of large-size display screens such as TV products is the exposed light around the data line Data, because there is a voltage difference between the Data line and the pixel electrode and the common electrode, refer to figure 1 For the two pixels shown, since the Gate signal is a progressive scan, the signal is in the form of a pulse. When a pixel is turned on as L255, the adjacent pixel is still in the L0 state, and at this moment Date has a voltage written, so the Data line and the pixel There is a voltage difference between the electrodes, which will cause an electric field around the Data line, such as figure 2 shown. It is precisely because of th...

Abstract

The invention provides a display panel and a display device. An array substrate is provided with first shading strips along the extension direction of a data line; since the dielectric constant of each first shading strip is lower than that of a liquid crystal material, intensity of an electric field around the data line can be weakened, and liquid crystal disorder is reduced; and since the firstshading strips reduce the amount of liquid crystal deflected by the electric field around the data line, light leakage around the data line can be reduced. Compared with the prior art, the display panel can reduce the width of a black matrix BM on a color film substrate, thereby improving aperture ratio.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a display panel and a display device. Background technique [0002] TFT-LCD (Thin Film Transistor-Liquid Crystal Display) is still the current mainstream display product. In recent years, major panel manufacturers have been continuously expanding their production scale. The market demand has grown with the popularity of smart phones and TVs in recent years. , Improving production efficiency and producing high-quality backplanes is the key to occupying the market. With the development of display technology, large-size display screens are becoming more and more popular. [0003] However, existing large-size display screens such as 75-inch 8K ADS TV products have serious light leakage along the direction of the data line. Therefore, it is difficult to achieve a transmittance of more than 50%. Contents of the invention [0004] The invention provides a display panel and ...
