Discussed is an organic light emitting display device including a display panel; a human body detection unit to detect a human body existing in front of the display panel; a human body determination unit to determine whether the human body exists and a location of the human body with respect to the display panel based on detection information from the human body detection unit; a brightness control unit to determine whether to control a brightness of the display panel based on a result of the determination by the human determination unit; and a timing controller to control image data provided to the display panel based on the determination from the brightness control unit. Accordingly, a viewer can view a sufficiently bright image, and energy can be saved and threshold voltage (Vth) difference can be compensated for.

Organic light emitting display device and method of controlling same

A timing controller, a display device, and a method of driving the same able to prevent a dark defect that would otherwise be formed when two or more image control methods are disclosed.

Timing controller, display device, and method of driving the same

An organic light emitting display device, can include a panel, a driving unit driving the panel, a timing controller controlling the driving unit, a power supply supplying power to the panel, a current detection unit detecting a current flowing through power line wiring of the panel and outputting the detected currents, and a power controller comparing the detected current with a current value configured internally and outputting a shutdown signal which turns off the power supply if the detected current exceeds the predetermined current value.

Organic light emitting display device and driving method thereof

The present invention has been made in an effort to provide an organic light emitting display device comprising a panel; a power supply supplying power to the panel; a current detection unit detecting a current flowing through power line wiring of the panel and outputting the detected current; and a power controller comparing the detected current with a current value configured internally and outputting a shutdown signal which turns off the power supply if the detected current exceeds the predetermined current value.

A backlight unit and a liquid crystal display using the same are provided. The backlight unit includes a plurality of lamps, a first balance printed circuit board (PCB) that commonly supplies a high voltage AC signal to electrodes at one side of each of the lamps, a second balance PCB that commonly supplies the high voltage AC signal to electrodes at the other side of each of the lamps, and a bottom cover that receives the lamps and the first and second balance PCBs. A plurality of vibration absorbing holes are formed in an area where the first and second balance PCBs are formed.

Backlight unit and liquid crystal display using the same

An inverter for liquid crystal display is disclosed. The inverter for liquid crystal display includes a switching circuit, a transformer, and first and second protective circuits. The switching circuit includes first and second switches and converts a direct current power input into an alternating current power. Each of the first and second switches alternatively performs a turn-on operation and a turn-off operation. The transformer transforms an alternating current power supplied from the switching circuit into a high-voltage alternating current power. The first protective circuit is connected to both terminals of the first switch and protects the first switch during turn-on and turn-off operations of the first switch. The second protective circuit is connected to both terminals of the second switch and protects the second switch during turn-on and turn-off operations of the second switch.
