摘要： Disclosed herein is a pixel circuit for an OLED panel, a display device having the pixel circuit and a method of driving the OLED panel. The pixel circuit for an OLED panel includes a switching element driven by a scan signal input through a corresponding one of scan lines sequentially selected from among a plurality of scan lines, and configured to transfer drive current based on luminance data input through a corresponding one of a plurality of data lines. An OLED emits light using the drive current transferred by the switching element. The OLED has an anode connected to a source terminal of the transistor and a cathode connected to a common electrode. Accordingly, problems such as the imbalance and deterioration of luminance attributable to the sequential driving of scan lines can be solved, and the complexity of circuits of a conventional AMOLED panel can be solved.

摘要： A home automation system using an infrared (IR)/radio frequency (RF) integration remote control module based on a network. At least one IR/RF integration remote control module (100) is disposed at a predetermined location of a home automation region. The IR/RF integration remote control module (100) with a wireless interface function integrates an RF modulation/reception/transmission function and an IR modulation/reception/transmission. A set-top box (200) is appropriately disposed so that it can carry out an interface function for controlling the IR/RF integration remote control module (100) and a wired/wireless Internet access function. The set-top box (200) receives various control commands over an Internet network using transmission control protocol/Internet protocol (TCP/IP) and controls the IR/RF integration remote control module (100). Even though various pieces of equipment using the conventional IR reception/transmission scheme or a new electronic product equipped with an RF module is added to the home automation system using an RF modulation scheme, an automation operation and a bidirectional control operation based on the integrated IR and RF transmission scheme can be appropriately carried out. Thus, the home automation system and method can be cost-effectively and conveniently implemented.
