Embodiment 1

[0031] Please refer to figure 1 , which is a partial structural diagram of the organic light emitting display according to Embodiment 1 of the present invention. Such as figure 1 As shown, the organic light emitting display 100 includes: a plurality of pixel units 110 arranged in a matrix and at least one compensation circuit 120; the plurality of pixel units 110 share the at least one compensation circuit 120, and the compensation circuit 120 uses to compensate the threshold voltage of the driving transistor of the pixel unit 110 .

[0032] Specifically, the organic light emitting display 100 includes a display area and a non-display area (not shown in the figure), and the display area includes scanning lines (not shown in the figure) and data lines (Di, Di+1 ), the data lines extend along the row direction and are arranged sequentially along the column direction, and the scan lines extend along the column direction and are arranged sequentially along the row direction. Th...

Embodiment 2

[0060] Please refer to Figure 4 , which is a partial structural diagram of the organic light emitting display according to Embodiment 2 of the present invention. Such as Figure 4 As shown, the organic light emitting display 100 includes: a plurality of pixel units 110 arranged in a matrix and at least one compensation circuit 120; the plurality of pixel units 110 share the at least one compensation circuit 120, and the compensation circuit 120 uses to compensate the threshold voltage of the driving transistor of the pixel unit 110 .

Abstract

The invention provides an organic light emitting display and a driving method thereof. The organic light emitting display comprises a plurality of pixel units in matrix arrangement and at least one compensation circuit. The plurality of pixel units share the at least one compensation circuit; and the compensation circuit is used for compensating threshold voltage of a driving transistor of each pixel unit. According to the organic light emitting display and the driving method thereof, the plurality of pixel units share one compensation circuit, so that not only compensation of the threshold voltage of each driving transistor is realized to prevent non-uniform brightness due to threshold voltage deviation, but also the number of the transistors in the pixel units can be reduced, higher pixel density is realized, and furthermore, resolution of the organic light emitting display is improved.

Description

technical field [0001] The invention relates to the field of flat panel display technology, in particular to an organic light emitting display and a driving method thereof. Background technique [0002] The organic light-emitting display uses an organic light-emitting diode (English full name Organic Lighting Emitting Diode, referred to as OLED) to display images. It is an active light-emitting display. -LCD) has different display methods, no backlight is required, and it has many advantages such as high contrast, fast response, and thinness. Therefore, the organic light emitting display is hailed as a new generation of display that can replace the thin film transistor liquid crystal display. [0003] An organic light emitting display includes a plurality of pixels for displaying images, the plurality of pixels are arranged in a matrix pattern, and each pixel includes an organic light emitting diode and a pixel circuit for driving the organic light emitting diode. The simp...
