Display and display panel thereof

Abstract

The invention discloses a display panel. The display panel comprises a first substrate, a second substrate, a liquid crystal layer clamped between the first substrate and the second substrate, a first metal layer and a first common electrode layer arranged on the first substrate, a gate insulation layer arranged on the first metal layer and the first common electrode layer, an active layer arranged on the gate insulation layer, an interlayer dielectric layer arranged on the active layer, and a second metal layer arranged on the interlayer dielectric layer and the active layer, wherein the second metal layer comprises a first sub-metal layer and a second sub-metal layer which are integrated, the first sub-metal layer is communicated with the active layer through a via hole formed in the interlayer dielectric layer, and the second sub-metal layer is located in an area corresponding to the first common electrode layer in the vertical direction and arranged on the active layer. The invention further discloses a display. In this way, difference in gray scale voltage change between positive frames and negative frames can be reduced, and the occurrence rate of flickering is reduced.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a display and a display panel thereof. Background technique [0002] Liquid crystal display panels are currently the mainstream display devices in the market due to their advantages of thinness and low power consumption. Mobile phone screens often use the display mode of FFS (Fringe Field Switching, fringe field switching) because of its wide viewing angle and It is not easily affected by slight changes in the thickness of the liquid crystal cell, commonly known as a hard screen; in order to reduce power consumption, the FFS display mode often requires a lower source (source) driving voltage, and the voltage difference between adjacent gray scales will be smaller, so it is easier Generate gray scale fluctuations, such as flicker, crosstalk, etc. [0003] There are multiple reasons for flicker, such as liquid crystal leakage, liquid crystal ion residue, thin film transistor leak...

AI Technical Summary

Problems solved by technology

Due to the influence of the feedback voltage, the leakage of the negative frame will be more serious, while the leakage of the positive frame will be slightly, this difference cannot be eliminated by adjusting the reference voltage
