Abstract

The invention discloses a liquid crystal display and a method for detecting and eliminating residual shadows. The liquid crystal display comprises a driving circuit board, a grid driver and a detecting module, wherein the driving circuit board is provided with a direct-current power converter and a time schedule controller, wherein the direct-current power converter is used for receiving a power signal, and the time schedule controller is used for receiving an input signal; the grid driver is electrically connected with the direct-current power converter and the time schedule controller and also electrically connected on a panel; and the detecting module is electrically connected with the grid driver and used for detecting the power signal and the input signal. When judging that the power signal and the input signal are abnormal, the detecting module outputs an output pulse signal to the grid driver to eliminate residual shadows.

Description

technical field [0001] The present invention relates to a liquid crystal display and its method for detecting and eliminating image sticking, in particular to a liquid crystal display and a method for detecting and eliminating image sticking that occurs on a liquid crystal display when a notebook computer switches output modes. its method. Background technique [0002] Flat panel displays, such as liquid crystal displays (LCD for short), are widely used in personal digital assistants (PDAs) due to their advantages of high image quality, small size, light weight, low driving voltage, and low power consumption Personal Digital Assistant, referred to as PDA), mobile phones, camcorders, notebook computers, desktop monitors, car monitors and projection TVs and other consumer communications or electronic products. [0003] The system architecture of traditional thin film transistor liquid crystal display (TFT-LCD) is as follows: figure 1 As shown, the thin film transistor liquid...
