发明名称 DISPOSITIVO DE RETRO-ILUMINAÇÃO, MÉTODO DE CONTROLE DE RETRO-ILUMINAÇÃO PARA UM DISPOSITIVO DE RETRO-ILUMINAÇÃO, E, DISPOSITIVO DE EXIBIÇÃO DE CRISTAL LÍQUIDO
摘要 The present invention relates to a backlight device, a backlight control method, and a liquid crystal display device that allow light-emission brightness or chromaticity to be corrected with high accuracy and low cost. A light source controller controlling a backlight causes processing to be sequentially performed for all the blocks SA-a(1) to (16) in a correction area SA-a. The processing includes setting an area SA-a of four areas SA-a to SA-d as a correction area and causing light emission in a block SA-a(1), which is a block in the correction area SA-a, and light emission in blocks SA-b(n) to SA-d(n) which are located in the three areas SA-b to SA-d other than the correction area SA-a and whose positions in the areas correspond to the block SA-a(n) to be sequentially performed. Then, the light source controller repeats similar operations for the remaining three areas SA-b to SA-d as correction areas. The present invention is applicable to, for example, a backlight of a liquid crystal display device or the like.
