摘要： An organic light emitting display capable of controlling brightness responsive to a user request. The display includes a brightness controller for controlling the brightness of a display region. The brightness controller includes a first look up table for storing widths of emission control signals corresponding to the image data of one frame period and a second look up table for storing at least one outside input mode for changing the widths of the emission control signals responsive to the outside input modes. By forming virtual look up tables, it is possible to vary the outside input modes in response to a user request in order to change the brightness of the display region while saving memory. Controlling the brightness of the display region also allows reducing power consumption, preventing the eyes of a user from getting tired, and maintaining image contrast of the display region.

摘要： A pixel circuit for a light emitting display. Adjacent pixels of the light emitting display coupled to one scan line share one first power supply line. A driving circuit in each pixel circuit drives first and second organic light emitting diodes (OLEDs). A switching circuit is coupled between the first and second OLEDs and the driving circuit to sequentially control the driving of the first and second OLEDs. Because two adjacent pixel circuits share one pixel power supply line and a plurality of OLEDs are coupled to one pixel circuit, it is possible to reduce the number of pixel circuits and the number of wiring lines of the light emitting display. Other circuit elements may also be shared between adjacent pixel circuits. Reducing the wiring and other elements of the pixel circuits makes it possible to increase the aperture ratio of the light emitting display.

摘要： Provided is an apparatus for driving a display panel. A short circuit can be detected by detecting a current (due to the short circuit) applied to a display panel through a low-dropout (LDO) regulator during a black data period. In addition, power applied to the display panel from a DC-DC converter can be turned off according to the short-circuit detection result.A level of a short-circuit current that can be detected by a short-circuit detecting unit may be adjusted by changing a ratio of a pass transistor of the LDO regulator and a sensing transistor of the short-circuit detecting unit, thereby detecting a micro-short-circuit current (several microamperes) that occurs due to a micro-short circuit.In addition, provided is an apparatus for driving a display panel capable of, in a case where power sources applied to a display panel are short-circuited due to a crack that occurs in the display panel, detecting this and turning off power applied to the display panel from a DC-DC converter.For this, the apparatus may be configured to detect a short circuit by detecting whether or not a drive current applied to the display panel through an LDO regulator exceeds a maximum drive current during an image data period due to a micro-short-circuit current that occurs due to a micro-short circuit, and to control an output voltage of the DC-DC converter by outputting a short-circuit detection signal to the DC-DC converter according to the short-circuit detection result, thereby detecting the micro-short circuit that occurs due to a crack generated during driving of the display panel.Accordingly, the apparatus can detect the micro-short circuit during the driving of the display panel and turn off power applied to the display panel from the DC-DC converter, thereby preventing the display panel from being more significantly damaged and protecting the DC-DC converter, the inductor, and the like.
