Problems solved by technology

The reason why t2 is greater than t1 is that when there is light, the impedance of the active layer increases compared to when there is no light, resulting in a slow rise in the driving voltage
And t2 is greater than t1, which will lead to the charging time T-t1 of the sub-pixel when there is light relative to the charging time T-t when there is no light 2 becomes shorter, resulting in the problem of different sub-pixel charging rates
The different charging ra

Abstract

The invention provides a source driver, a driving system, a liquid crystal display device and a correction method thereof, relates to the technical field of display and can improve the display effectof the liquid crystal display device. The source driver comprises a plurality of driving units, wherein the driving unit is connected with a data input end, a data voltage output end and at least twocontrol ends; the driving unit is configured to output an analog data voltage through the data voltage output end according to a data signal input by the data input end; and moreover, under the control of the control signals input by the at least two control ends, the data voltage output end outputs different output impedances.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a source driver, a driving system, a liquid crystal display device and a correction method thereof. Background technique [0002] Liquid Crystal Display (LCD) is widely used in modern information devices such as TVs, notebooks, computers, mobile phones, and personal digital assistants due to its small size, low power consumption, no radiation, and relatively low manufacturing costs. . [0003] The LCD generally includes a liquid crystal display panel and a backlight module that provides a light source for the liquid crystal display panel. The backlight module can emit light under the control of a PWM (pulse width modulation, pulse width modulation) signal. [0004] According to the PWM signal, the light emitted by the backlight module (that is, the light incident on the liquid crystal display panel) changes alternately between bright and dark at a certain frequency. That is, t...
