A kind of thin film transistor array substrate and liquid crystal panel

Abstract

The invention provides a thin film transistor array substrate which comprises sets of thin film transistors and a number of RGB pixel units. Each set of thin film transistor comprises three thin film transistors located in first, second and third rows. Three thin film transistors are corresponding to an R subpixel, a G subpixel and a B subpixel in a corresponding RGB pixel unit. The length-width ratio of conductive channels of all thin film transistors in each row is not exactly the same, but is within a preset ratio range, so that the total leakage current of the row is within a preset current range. The leakage current is only related to the width-length ratio of the conductive channel of the thin film transistor. The larger the width-length ratio W / L is, the larger the drain current is. The smaller the width-length ratio is, the smaller the drain current is. According to the invention, burrs in a control signal output by a driving chip are avoided; the display quality of a liquid crystal panel is improved; noise can be avoided; and the power consumption of a display module is reduced. The invention further provides the liquid crystal panel.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a voltage output control circuit and a liquid crystal display. Background technique [0002] With the rapid development of the small and medium-sized electronic display industry, people have higher and higher requirements for the resolution and other quality of small and medium-sized LCD liquid crystal displays. The improvement of the display quality is closely related to the transmission rate of the display data and the integrity of the signal. For the current small and medium-sized LCD display screens, all the multiplexers are simultaneously turned on during the time period when the gates are turned on, so as to complete the charging of the RGB sub-pixels. But when all the multiplexers are turned on, it will cause the display module to instantly form a large pumping load on the LCD panel driver chip, which will cause glitches in the control signal output by the driver chip, w...
