Embodiment Construction

[0038] Please refer to figure 2 , figure 2 A schematic diagram of a device 200 for reducing ghost images displayed on a liquid crystal panel 100 is described for an embodiment of the present invention, wherein the liquid crystal panel 100 is divided into five blocks 101-105 from top to bottom, but the present invention is not limited thereto The liquid crystal panel 100 is divided into five blocks 101-105. The device 200 includes a look-up table 202 and a timing controller 204 . Such as figure 2 As shown, the look-up table 202 is used to store an output enable signal corresponding to each of the five blocks 101-105, wherein each output enable signal corresponds to a predetermined duty cycle. That is, the duty cycle of each output enable signal is different from the duty cycle of other output enable signals. The timing controller 204 is used to receive the stereoscopic image data IDs corresponding to the five blocks 101-105 in each frame from a Graphic Processing Unit (G...

Abstract

The invention provides a device for reducing ghost images displayed on a liquid crystal display panel. The liquid crystal display panel is separated into a plurality of sections. The device comprises a look-up table and a time schedule controller. The look-up table is used for storing an output enable signal corresponding to each section in the sections, wherein each output enable signal corresponds to a preset work period; and the time schedule controller is used for receiving stereoscopic image data corresponding to the section, reading the output enable signal corresponding to the section from the look-up table, and outputting the output enable signal corresponding to the section and the stereoscopic image data corresponding to the section to the liquid crystal display panel.

Description

technical field [0001] The present invention relates to a liquid crystal panel display device and method thereof, especially to a device and method for reducing ghost images displayed on a liquid crystal panel. Background technique [0002] In the display technology of the current shutter 3D glasses, the problem of ghosting exists in the image display. Please refer to figure 1 , figure 1 It is to illustrate the left-eye image L of the stereoscopic image, the right-eye image R of the stereoscopic image, the liquid crystal response time RT, the scanning lines L1-LN of the liquid crystal panel, the left-eye lens GL of the shutter glasses, the right-eye lens GR of the shutter glasses, and the blank Schematic diagram of blanking time BT. Such as figure 1 As shown, in the time period T1, when the right eye glass GR is opened, the liquid crystal corresponding to the scanning line LN has not completed the state transition (as shown in FIG. figure 1 ), that is, the data correspo...
