Abstract
Description
technical field
[0001] The invention relates to the display field, in particular to a backlight module device based on a polarized light source, which is a liquid crystal display backlight module device based on directly emitting polarized light. Background technique
[0002] The backlight module mainly provides a uniform and high-brightness light source for the LCD panel. The basic principle is to transform the commonly used point or line light source into a high-brightness and uniform luminance surface light source product through a simple and effective light mechanism. Generally, the linear light source of cold cathode tube (CCFL) enters the light guide plate through the reflector, transforms the linear light source into a uniform surface light source, and then improves the brightness and Uniformity. In recent years, with the improvement of liquid crystal display manufacturing technology, under the trend of large size and low price, the backlight module needs to consider...
