A display device includes: a substrate including a display area in which pixels are disposed and a non-display area; a common voltage transfer line disposed in the non-display area and transferring a common voltage to the pixels; a data output wire disposed at the non-display area and connected to a data line which transfers a data voltage to the pixels; and a sacrificial wire disposed between the common voltage transfer line and the data output wire and not connected to the data line.
Abstract:
In order to display an image in a display device, in which a plurality of sub pixels within a unit pixel receives driving power from one driving power line, a driving voltage stability weak pattern is detected by analyzing image data. When the input image is determined as the driving voltage stability weak pattern, a white balance correction gain of each sub pixel is decreased while a ratio among the white balance correction gains of the sub pixels is maintained. Target luminance for displaying the input image is changed. A voltage level of the driving power is change in accordance with the changed target luminance.

Abstract:
A display device includes: a display panel including a pixel electrically connected to each of a data line, a first power line, a second power line, and a third power line; a power supply to provide a first power voltage to the first power line, and a second power voltage to the second power line; and a driver to provide a data voltage to the data line, and a third power voltage to the third power line. The driver is to determine whether a sensing voltage measured at the second power line is out of a reference range, and to limit the supply of the third power voltage when the sensing voltage is out of the reference range.

A sensor includes: a hole; a sensing area formed around the hole, wherein at least one sensor is in the sensing area; and a crack detector configured to output a first crack signal if a comparison value obtained by comparing a detected value from the at least one sensor with a reference value exceeds an error range.
Abstract:
An organic light emitting display device includes a display panel having pixels and a display panel driver driving the display panel. Each of the pixels includes an organic light emitting diode, and the display panel driver selects one of the pixels, determines a reference grayscale value, compares a grayscale value, and determines the selected pixel as a low grayscale pixel when the grayscale value is lower than the reference grayscale value and higher than a black grayscale value. Some of the low grayscale pixels display the black grayscale value when there are more than one neighboring low grayscale pixels. The reference grayscale value is determined based on a reference grayscale variable, and the reference grayscale variable includes at least one of a temperature of the display panel, a time period when the selected pixel emits light, and a wavelength of light emitted by the selected pixel.
