  • Patent number: 7663577
    Abstract: An organic light emitting display (OLED) device including a plurality of electroluminescent (EL) panels that are coupled with one another. In order to facilitate the coupling of the EL panels, respective data drivers are disposed at one side of pixels, and a scan driver and an emission control driver are formed in each of the EL panels. Thus, surfaces of the EL panels that are not connected to data drivers may be coupled with one another to form the OLED device. In the OLED device, a data driver is not formed at interfaces between the EL panels, and uniform pixels are arranged, so that non-uniformity in luminance may be prevented.

  • Publication number: 20050083291
    Abstract: An SRAM cell having a latch circuit including two inverters coupled in a chain format. Each inverter is coupled to power through a transistor, and the transistor is turned off when data is written to the SRAM. As a result, the data is easily written to the SRAM cell without data collision since performance of the latch circuit is degraded. Such SRAM cell may be used in a flat panel display to temporarily store digital signals corresponding to data signals for displaying video.
