Embodiment 1

[0039] An OLED pixel structure, including a plurality of gate lines and data lines for driving OLED pixel units, the plurality of OLED pixel units are arranged in a matrix, and the OLED pixel units are scanned simultaneously by L rows, and are The OLED pixel units in every L rows scanned at the same time are set as a pixel block, where L≥3.

[0040] Wherein, a plurality of the OLED pixel units are arranged in an M*N (row*column) matrix, each of the OLED pixel units includes a plurality of color sub-pixel units, and each sub-pixel unit is arranged circularly in columns according to the color , the number of data lines is LN, and each L data line is respectively connected to the sub-pixel units in different rows of the same column; the number of gate lines is (2 / 3)M, and each gate line is connected to At least the sub-pixel units in adjacent rows in the same column are connected.

[0041] In this example, if Figure 3-5 As shown, L is preferably three, that is, the pixel units...

Embodiment 2

[0055] The difference between this embodiment and Embodiment 1 is that each pixel unit in this embodiment includes sub-pixel units of four colors, and the four colors are red, green, blue, and white respectively.

[0056] In this embodiment, the connection mode of the gate line and the data line in the OLED pixel structure and the output sequence of the image data in the timing control unit are similar to those in the first embodiment. Since the pixel unit includes sub-pixel units of four colors, specifically, the connection between the data line and the gate line in the pixel structure is as follows: Figure 9 Shown; the input sequence of the image data in the timing control unit is as follows Figure 10 As shown, the output sequence of the image data is as follows Figure 11 shown.

Embodiment 3

[0058]The difference between this embodiment and Embodiments 1 and 2 is that the connection mode of the gate lines in each pixel block in this embodiment is the same as that of the gate lines in the prior art, that is, each of the pixel blocks Three gate lines 3 are arranged in the pixel block, and each gate line is connected to a row of sub-pixel units, such as Figure 12 shown.

[0059] In Embodiments 1-3, the organic light-emitting diode pixel structure adopts a three-row scanning method during scanning, and three rows of sub-pixel units belonging to the same pixel block are turned on at the same time, and the image data of the three rows of sub-pixel units are simultaneously refreshed ; Cooperate with the image data processing method of the corresponding timing control unit for data processing, which can meet the image data arrangement requirements of this pixel structure. Since the row scan frequency is reduced to one-third of the row scan frequency in the prior art, the...

Abstract

The invention belongs to the technical field of display and particularly relates to an OLED (Organic Light Emitting Diode) pixel structure and a display device. The OLED pixel structure comprises a plurality of grid lines and data lines for providing drive to OLED pixel units; the OLED pixel units are arranged in a matrix form and are scanned per L rows each time; every L rows of OLED pixel units which are simultaneously scanned are arranged as a pixel block, wherein L is greater than or equal to 3. The OLED pixel structure can be used for effectively improving the problem that a memory capacitor Cs is undercharged, meanwhile correspondingly improving the RC time delay problem of the data lines. thus correspondingly improving the display uniformity of the display device and ensuring the display quality of the display device, and is especially applicable to large-size OLED display devices with ultra-high resolution.

Description

technical field [0001] The invention belongs to the field of display technology, and in particular relates to an organic light emitting diode pixel structure and a display device. Background technique [0002] OLED (Organic Light-Emitting Diode, Organic Light-Emitting Diode) display device is an emerging flat-panel display device, which has broad application prospects due to its advantages such as simple preparation process, low cost, low power consumption, and fast response speed. [0003] A pixel unit in an OLED display device includes a plurality of pixel units arranged in a matrix. According to the driving mode, the pixel unit is divided into two types: a passive matrix (Passive Matrix, PM for short) driving mode and an active matrix (Active Matrix, AM for short) driving mode. Because AM-OLED has obvious advantages in terms of viewing angle, color reproduction, power consumption, and response time, it has been widely used. [0004] In the OLED display device, the displ...
