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...
