Patent ID: 8436794

Claim:
A device which optimizes brightness of a liquid crystal display panel, the device comprising: a plate on which to place a target liquid crystal display panel subject to optimization; a back light configured to provide light to the target liquid crystal display panel; a connecting unit configured to connect to a pad unit of the target liquid crystal display panel; a detecting unit comprising an optical sensor placed over the target liquid crystal display panel and configured to produce brightness data of the target liquid crystal display panel being illuminated by the provided light, wherein the optical sensor is configured to detect brightness of light that passes through a portion of the target liquid crystal display panel under the optical sensor, the optical sensor having a maximum sight angle of 5° to 10°; a comparative unit configured to compare the brightness data of the target liquid crystal display panel with a standard brightness data of a standard liquid crystal display panel that is different from the target liquid crystal display panel subject to optimization; and a processing unit configured to produce an operation voltage for the target liquid crystal display panel based on the comparison of the brightness data with the standard brightness data.
