    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: 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 photosensor circuit includes a read-out circuit and a determiner. The read-out circuit includes: a first photosensor which outputs a first reference current corresponding to an intensity of a first reference light; a second photosensor which outputs a second reference current corresponding to an intensity of a second reference light; a third photosensor which outputs an external light current corresponding to an intensity of an external light; a first current memory which senses the first reference current; a second current memory which senses a difference between the first and second reference currents; and a storage capacitor which charges during a first period of time and discharges during a second period of time. The determiner calculates the intensity of the external light based on the intensities of the first and second reference lights and durations of the first and second periods of time.
