摘要： With the related art, the choice of locations for disposition of ambient light photosensors is narrow, and consequently it is difficult to respond flexibly to user specifications for differing structures of the case. With a display device of the invention however, ambient light photosensors can be disposed laterally and longitudinally, enabling the intensity of light in longitudinal or lateral directions to be sensed at the same levels. Also, bridge-connecting together the longitudinally-disposed ambient light photosensors enables ambient light photosensors to be disposed close to the outer periphery of the display area in both the longitudinal and lateral directions. Thereby, the problems with the related art can be resolved.

摘要： A liquid crystal display according to an embodiment of the present invention includes a liquid crystal display panel, an illumination unit for the liquid crystal display panel, a plurality of photodetectors, and a control unit Cnt to control the brightness of the illumination unit. The photodetectors are TFT ambient light photosensors LS1 to LS3, for example, which produce outputs that require time to reach a predetermined value, which the time is correlated with the intensity of ambient light. Detection circuits coupled to the photodetectors include circuits (Cmp1 to Cmp3) logically inverted when an output from the TFT ambient light photosensors LS1 to LS3 reaches a predetermined value. The control unit Cnt includes a discrimination implement Maj that determines that the intensity of ambient light has changed when outputs from the majority of the detection circuits are logically inverted. The above-mentioned structure provides a liquid crystal display that does not use plurality of interface circuits nor A/D converters, nor experience frequent malfunctions for automatic control of the brightness of the illumination unit according to the intensity of ambient light.
