Problems solved by technology

[0005] Organic electroluminescent displays emit light through organic light-emitting diodes. However, in actual operation, as time goes by, organic light-emitting diodes will deteriorate and cause changes in efficiency, resulting in corresponding pixels that cannot display images with desired brightness. If this degradation continues, the life of the organic light-emitting diode will be greatly shortened

Abstract

The invention discloses a pixel, a driving method, a display panel with the pixel and a display device. The pixel comprises an organic light-emitting diode, a driving unit and a compensation unit, thedriving unit is combined to the organic light-emitting diode, and the compensation unit is combined to the data line and the organic light emitting diode, wherein when the pixel is in the compensation time period, the compensation unit is used for obtaining the difference value between the data voltage provided by the data line and the anode voltage of the organic light-emitting diode, the driving unit adjusts the driving current according to the difference value, and the driving current is used for driving the organic light-emitting diode to emit light. According to the present invention, the driving current can be adjusted according to the difference value between the data voltage provided by the data line and the anode voltage of the organic light-emitting diode, so that the driving current rises to compensate the degradation of the organic light-emitting diode, and the reduction of the brightness of the organic light-emitting diode can be reduced.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a pixel, a driving method, a display panel with the pixel, and a display device. Background technique [0002] Today, with the development of multimedia technology and the advent of the information society, the requirements for electronic equipment are getting higher and higher, such as display equipment, communication equipment and so on. [0003] Taking display equipment as an example, in recent years, three new display technologies have emerged: plasma display, field emission display and organic electroluminescent display, all of which have made up for the shortcomings of cathode ray tubes and liquid crystal displays to a certain extent. [0004] Among them, Organic Light Emitting Devices (OLED) has a series of advantages such as self-luminescence, low-voltage DC drive, full curing, wide viewing angle, and rich colors. Compared with liquid crystal displays, organic li...
