Abstract

The invention provides a display panel and a pixel unit thereof. The pixel unit comprises a gate line, a data line, a voltage dividing control line, a first transistor and a second transistor. The first transistor has a first gate, a first source and a first drain. The second transistor has a second gate, a second source and a second drain. The first gate and the second gate are respectively coupled with the gate line. One in the first source and the first drain is coupled with the data line, and the other one is coupled with one in the second source and the second drain. The other one in thesecond source and the second drain is coupled with the voltage dividing control line. The first transistor has a first channel length, the second transistor has a second channel length. The ratio between the second channel length and the first channel length is equal with or smaller than 0.9.

Description

technical field [0001] The present invention relates to a display panel and its pixel unit, in particular to a display panel and its pixel unit which can reduce image sticking. Background technique [0002] In the existing display panel technology, in order to solve the brightness difference caused by viewing the display panel at a large viewing angle, a technical solution is provided, wherein another set of different pixel voltages is provided in the same pixel through another set of pixel structures, Thereby, the liquid crystal molecules in the same pixel area have two different inclination angles. In this way, the human eye can see a relatively average optical performance at different viewing angles. [0003] In the prior art, the additionally provided pixel structure (hereinafter referred to as sub-pixel) generally adjusts its divided voltage by connecting another transistor in series. However, this voltage dividing structure easily causes the transistors of the sub-pi...
