OLED (organic light emitting diode) pixel structure, driving method, driving circuit and display device

Abstract

The invention provides an OLED (organic light emitting diode) pixel structure, a driving method, a driving circuit and a display device, and belongs to the technical field of display. The OLED pixel structure comprises multiple pixel units arranged in a matrix manner, wherein each pixel unit comprises multiple sub pixels in different colors, at least two sub pixels in each pixel unit share one compensating circuit, and the different sub pixels sharing the same compensating circuit are displayed respectively at different time periods of output of one frame of image. With the adoption of the technical scheme, the dynamic resolution of the display device can be improved, and the display effect is optimized.

Description

technical field [0001] The invention relates to the field of display technology, in particular to an OLED pixel structure, a driving method, a driving circuit and a display device. Background technique [0002] In the prior art, in order to solve the problem of difficult high-resolution layout of an AMOLED (Active-matrix organic light emitting diode, active-matrix organic light emitting diode) display device, two sub-pixels share a compensation circuit. Such as figure 1 As shown, the AMOLED pixel structure includes a plurality of pixel units, and each pixel unit includes a blue sub-pixel 1, a red sub-pixel 2, and a green sub-pixel 3, and the sub-pixels in the first row and the corresponding sub-pixels in the second row share a The compensation circuit, the sub-pixels in the third row share a compensation circuit with the sub-pixels in the corresponding position in the fourth row, ..., the sub-pixels in the 2k-1 row and the sub-pixels in the 2kth row share a compensation cir...

Problems solved by technology

[0003] However, when the above-mentioned display device displays a dynamic picture, such as a single horizontal line that moves one pixel unit per frame, as figure 2 As shown, the pixel units of odd rows are driven for display in the first half of the first frame of image output, and a single horizontal line can be displayed at this time, and the pixel units of even rows are driven for display in the second half of the first frame of image output , but at this time, the single horizontal line is located in the first row of pixel units, so there will be no picture display during the second half of the first frame of image output; in the first half of the second frame of image output, the pixel units of odd rows are driven display, but at this time the single horizontal line is located in the second row of pixel units, therefore, there will be no picture display during the first half of the second frame of image output, and the even-numbered row of pixel units will be driven during the second half of the second frame of image output For display, a single horizontal line can be displayed at this time; in the first half of the third frame of image output, the pixel units of odd rows are driven for display, and a single horizontal line can be displayed at this time, and in the second half of the third frame of image output Segment drives the pixel units of even rows for display, but at this time the single horizontal line is located in the third row of pixel units, so there will be no picture display in the second half of the third frame image output; in the first half of the fourth frame image output During the period of time, the pixel units of odd rows are driven for display, but at this time the single horizontal line is located in the pixel unit of the fourth row. Therefore, there will be no picture display during the first half of the fourth frame of image output, and after the fourth frame of image output Drive the pixel units of the even-numbered rows for display in the half-time period, and a single horizontal line can be displayed at this time

like this figure 2 As shown, the time interval between the single horizontal line displayed in the first frame and the single horizontal line displayed in the second frame is relatively far, and the time between the single horizontal line displayed in the second frame and the single horizontal line displayed in the third frame is too close, so that the original The smooth picture has a divided feeling, which makes the dynamic resolution of the display device decrease
