Problems solved by technology
In this way, in order to reduce the brightness unevenness on the liquid crystal panel, the distance between the lamp and the diffusion plate is usually increased to a predetermined distance, which increases the overall thickness of the LCD, so that the driving chip connecting the printed circuit board and the liquid crystal panel The package becomes longer which ultimately increases the manufacturing cost
[0008] Also, the distance between the lights and the diffuser can cause the diffuser to sag due to its own weight
Also, when the LCD panel is placed on top of the diffuser, the sag can be even worse

A liquid crystal display achieving brightness uniformity, thereby reducing manufacturing costs, includes a liquid crystal panel having a first region and a second region that exhibit different brightnesses when a predetermined data voltage is applied, a memory storing a reference brightness that is to be exhibited by the liquid crystal panel when the predetermined data voltage is applied, and a brightness correction unit receiving image data corresponding to the predetermined data voltage and correcting the image data so that the first region and the second region exhibit the reference brightness.
Description
technical field [0001] The present invention relates to liquid crystal displays, and, more particularly, to liquid crystal displays that achieve brightness uniformity, thereby reducing manufacturing costs. Background technique [0002] Generally, a liquid crystal display (LCD) includes a TFT substrate having thin film transistors (TFTs) for switching pixels, a color filter substrate having color pixels, and a liquid crystal layer interposed between the TFT substrate and the color filter substrate. . Liquid crystal molecules constituting the liquid crystal layer are aligned according to an electric field generated between the TFT substrate and the color filter substrate, and a light transmissive index changes according to the alignment of the liquid crystal molecules. [0003] Such LCDs are classified into edge type LCDs and direct type LCDs according to the position of lamps used as light sources in the backlight module. [0004] The edge type LCD includes at least one lam...
