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.

摘要： A liquid crystal display device 1 of the invention has a liquid crystal display panel in which a liquid crystal layer 14 is provided between a TFT substrate 2 and a CF substrate 25 that has a common electrode 26, a light sensing component LS1 with a TFT photosensor that senses external light, and an illuminating means controlled according to the output of the light sensing component. The light sensing component is deployed at the periphery of the TFT substrate's display area DA and uses a thin film transistor as photosensor. A capacitor C is connected between source and drain electrodes SL, DL for such TFT photosensor. One of the capacitor's terminals is connected to a standard voltage source VS via a switch element SW, and the other to the common electrode 26. Voltage that is always lower than the voltage applied to the common electrode by an amount corresponding to a reverse bias voltage is applied to the gate electrode GL for the TFT photosensor. The capacitor's voltage a certain time after the switch element turns off is output. As a result, it will be possible to provide a liquid crystal display device in which the light sensing component incorporated in the liquid crystal display panel is not susceptible to the influence of the drive signals for the display panel, and in which the light sensing component does not induce deterioration of the liquid crystals.

摘要： A liquid crystal display device 1 according to an embodiment of the present invention includes a liquid crystal display panel, a photodetector unit LS1 that is built into the liquid crystal display panel and has a TFT ambient light photosensor, an ambient light photosensor reader Re1 for reading a voltage due to photo-leakage from the TFT ambient light photosensor, and a control means 20 for controlling the photodetector unit and the ambient light photosensor reader, and a backlight 24, etc., according to an output from the ambient light photosensor reader. The photodetector unit has a switching element SW2 coupled between a source line coupled to the TFT ambient light photosensor's source electrode SL and a drain line coupled to the TFT ambient light photosensor's drain electrode DL. The control means 20 makes the source line and the drain line of the TFT ambient light photosensor be coupled to a common potential when changing a gate voltage of the TFT ambient light photosensor by keeping the switching element SW2 turned on. It is therefore possible to provide a liquid crystal display device that utilizes a thin film transistor as an ambient light photosensor and prevents degradation of an ambient light photosensor element due to a biased polarity voltage applied to the gate electrode.
