The present invention relates to a pixel sensing device capable of compensating for an error included in a test current itself by supplying, when a pixel current is sensed, the test current used in the sensing of each channel circuit error.

Pixel sensing device and panel driving device

Disclosed is a sensing circuit of a display device for external compensation of an OLED. The sensing circuit includes a current receiving unit configured to receive a pixel current containing a leakage current, convert the pixel current at a preset current ratio, and output the converted pixel current; a current source unit; a current sinking unit; a current detection unit; and a detection signal output unit configured to sample an offset voltage corresponding to the leakage current using the detected current.

Sensing circuit of display device for sensing pixel current

The present invention relates to technology for driving a display device, and provides technology which, in sensing pixels arranged in a panel, processes a signal having a wide range by using a low-voltage element.

Pixel sensing apparatus and panel driving apparatus

An electronic device is provided. The electronic device includes a processor configured to execute an application, and a display configured to display a first window corresponding to the application, wherein, in response to a specified event, the processor is further configured to adjust a transparency of the first window and to output, to a lower layer than a layer of the first window, a second window overlapping at least a part of an area of the first window.

Security of screen in electronic device

An indoor unit of a ceiling type air-conditioner includes a main body having an inlet port and an outlet port provided at a lower portion thereof, a heat exchanger having a tube through which a refrigerant flows, a blowing fan which forcibly causes air to flow, and a control box comprising a case which is fixed to the main body and a cover which is rotatably coupled to the case so as to open and close the case and to which a printed circuit board having electronic components mounted thereon is fixed.

Indoor unit of ceiling type air-conditioner

An automatic loading and unloading apparatus using servo motors allows simultaneous loading and unloading of two or more semiconductor device packages into and from test devices. The loading and unloading apparatus has a feeding mechanism which has a feed container carrying two semiconductor device packages which have not yet been tested; a loading tool for transferring those two semiconductor device packages from the feed container to a centering position; a DC test contact tool; an insertion tool; a removal tool; and a sorting station for sorting the semiconductor device packages depending on results of a burn-in test. The tools of the apparatus are driven by the action of servo motors, thereby allowing independent movements thereof in the vertical and horizontal directions.
