Lateral-entering type backlight module with uneven-size backlight partitions and design method of lateral-entering type backlight module with uneven-size backlight partitions

Abstract

The invention relates to a lateral-entering type backlight module with uneven-size backlight partitions and a design method of the lateral-entering type backlight module with uneven-size backlight partitions. Relative size of each backlight partition of the lateral-entering type backlight module meets the condition that sizes of backlight partitions sorted in the front are relatively large. The sorting method comprises the following steps: based on the preset liquid crystal display panel signals and backlight scan time sequence, simulating backlight partition lighting according to even-size backlight partitions to display the liquid crystal display panel signals; analyzing interference signal area number and interference signal distance which appear when each backlight partition is lighted during simulation process; and sorting according to crosstalk degree during lighting of each backlight partition, wherein backlight partitions with small cross talk degree are sorted in the front. Further provided is the design method of the lateral-entering type backlight module. According to the lateral-entering type backlight module with uneven-size backlight partitions and the design method of the lateral-entering type backlight module with uneven-size backlight partitions, the liquid crystal display panel signals and the backlight scan time sequence are adopted to judge the influence of the backlight partitions on cross talk, the relative sizes of the backlight partitions are changed to improve crosstalk, and displaying quality is improved.

Description

technical field [0001] The invention relates to liquid crystal display technology, in particular to a side-entry backlight module with non-uniform size backlight partitions and a design method thereof. Background technique [0002] With the rapid development of LED TV, it is about to enter another stage - 3D LCD TV. In 3D LCD TVs, there is a shutter glass 3D display technology that is currently the most commonly used technology. It uses the backlight to flash in different areas to display the signals of the left and right eyes separately, and then paired with glasses that flash synchronously, the left and right eyes can see different images. The shutter-type 3D display technology uses image processing technology to make the human eye feel the visual effect like a stereoscopic image. It mainly includes: making the left and right eye image frame (frame) signals alternately output to the liquid crystal panel, driving the liquid crystal panel to form left and right images respe...

Problems solved by technology

[0003] However, LCD 3D displays have a disadvantage: since the LCD panel itself does not emit light, the backlight must be used as a light source. Due to cost factors, the backlight partitions cannot be made too detailed

Since the existing edge-lit backlight partitions are even-numbered partitions, when an error signal occurs, the impact on the top and bottom is different. In this example, the lighting time of the backlight partition is closer to the upper error signal, and the crosstalk above the liquid crystal panel 40 is relatively strong. Seriously, the upper and lower crosstalk of the LCD panel 40 is asymmetrical

If the signal of the liquid crystal panel is directly adjusted so that the backlight partition is lit at the center of the signal of the liquid crystal panel, although the crosstalk between the top and bottom of the liquid crystal panel 40 can be made close to symmetry, but because the backlight partition is an even number, the image quality at the center will be sacrificed, and the crosstalk will become larger.
