Embodiment Construction

[0025] Please refer to FIG. 1 . FIG. 1 is a functional block diagram of a liquid crystal display 10 of the present invention. The liquid crystal display 10 includes a power supply 12 , a timing controller 14 , a plurality of source drivers 16 , a plurality of gate drivers 18 , a detection circuit 22 and a liquid crystal display panel 20 . The LCD panel 20 includes a plurality of pixel units 28 . The power supply 12 is used to supply all circuits in the liquid crystal display 10 including the operating voltage required by the timing controller 14, multiple source drivers 16, multiple gate drivers 18 and the detection circuit 22. 1 only shows the connection relationship between the power supply 12 and the detection circuit 22 . When the clock signal generated by the timing controller 14 is transmitted to the plurality of gate drivers 18, the plurality of gate drivers 18 will generate scanning signals and transmit them to the liquid crystal display panel 20 through the scanning ...

Abstract

A liquid crystal display enabling to eliminate ghost off consists of face plate with multiple pixel unit for displaying image; detection circuit for generating a switch signal; source electrode driver including a processing unit for providing a data signal voltage, multiple the first switch unit for connecting data signal voltage through to each first pixel unit of said face plate when switch-signal is on the first state and multiple the second switch unit for electric-connecting through each first pixel unit when switch signal is on the second state.

Description

【Technical field】 [0001] The invention relates to a liquid crystal display and a method for eliminating residual images, in particular to a liquid crystal display and a method for eliminating residual images by using a charge sharing effect. 【Background technique】 [0002] Displays with advanced functions have gradually become an important feature of today's consumer electronics products. Liquid crystal displays have gradually become widely used in various electronic devices such as mobile phones, personal digital assistants (PDAs), digital cameras, computer screens or notebook computer screens. high resolution color screen monitor. [0003] However, when the liquid crystal display is turned on and off, the charge of the previously displayed image still remains in the liquid crystal capacitor of the liquid crystal display panel, so image sticking occurs. In order to avoid the problem of image sticking, prior art such as U.S. Patent No. 6,476,590 discloses that after shutdow...
