摘要： A display device includes a light emitting element, a capacitor, a driving transistor, and first to third switching units. The capacitor is connected between a first node and a second node. The driving transistor has an input terminal connected with a first voltage, an output terminal, and a control terminal connected with the second node, and it outputs a driving current to the light emitting element. The first switching unit selects and connects one of a data voltage and a second voltage to the first node. The second switching unit switches a connection between the second voltage and the second node. The third switching unit selects and connects one of the second node and the light emitting element to the output terminal of the driving transistor.

摘要： A liquid crystal display (LCD) apparatus includes a first substrate, a second substrate, a liquid crystal layer and a backlight assembly. The first substrate includes a display part and a sensor part. The sensor part is disposed in a peripheral area of the display part and senses external light. The second substrate is disposed opposite to the first substrate. The liquid crystal layer is disposed between the first substrate and the second substrate. The backlight assembly is disposed adjacent to the second substrate to expose the first substrate and to provide light. A light detecting function of the sensor part may be increased, so that the backlight may be used effectively and the power consumption of the display apparatus may be reduced.
摘要翻译：液晶显示器（LCD）装置包括第一基板，第二基板，液晶层和背光组件。第一基板包括显示部和传感器部。传感器部分设置在显示部分的外围区域中并感测外部光。第二基板与第一基板相对设置。液晶层设置在第一基板和第二基板之间。背光组件设置成与第二衬底相邻以暴露第一衬底并提供光。可以增加传感器部分的光检测功能，使得可以有效地使用背光，并且可以减少显示装置的功耗。
