Abstract: A display panel includes input power supply line coupled to a power supply at one or more edge portions of the display panel, and an output power supply line coupled to the input power supply line at a predetermined portion of the display panel. The input power supply line receives the power supply voltage, and the output power supply line receives the power supply voltage from the input power supply line. The power supply is coupled to the output power supply line at the one or more edge portions of the display panel, and receives the power supply voltage from the output power supply line to adjust a voltage level of the power supply voltage based on the power supply voltage from the output power supply line. The predetermined portion is at a location different from an edge of the display panel.

Abstract: A display device includes a display panel, a dither table memory device, a dithering processor, and a display panel driver. The display panel includes a plurality of pixels. Dither tables are stored in the dither table memory device. The dithering processor selects a target dither table corresponding to a grayscale level of input data from among the plurality of dither tables and performs a dithering operation on the input data using the target dither table to generate dither data. The display panel driver drives the display panel based on the generated dither data.

Abstract: A display panel module, organic light-emitting diode (OLED) display and method of driving the same are disclosed. In one aspect, the module includes a display panel divided into a first portion and a second portion and a plurality of scan and data lines divided into groups arranged in the first and second potions. The module further includes a first scan driver configured to sequentially apply scan signals to each of the first and second scan line groups. The first scan driver is further configured to substantially simultaneously apply the scan signals to corresponding scan lines of the first and second scan line groups. The module also includes a first data driver configured to output first data voltages to the first data line group and a second data driver configured to output second data voltages to the second data line group with the same timing as the first data driver.

Abstract: An organic light-emitting diode (OLED) display and a method of driving the same are disclosed. In one aspect, the method includes displaying an image on a display panel based at least in part on a first power voltage provided through a first power line and a second power voltage having a first voltage level provided through a second power line. The display panel is configured to receive the first and second power voltages from a power supply unit. The method also includes providing the second power voltage having a second voltage level higher than the first voltage level to the display panel through the second power line, detecting a second power line current flowing through the second power line when the second power voltage has the second voltage level, and turning off the power supply unit when the second power line current is detected.
