Problems solved by technology

[0003] In the application of AM OLED (Active Matrix Organic Light Emitting Diode, Active Matrix Organic Light Emitting Diode) to realize FULL HD, usually, each source drive channel in OLED drives a column of pixels or sub-pixels; however, it is limited by the structure of OLED itself , in order to reduce the number of source drive channels, data selector Mux is sometimes used, so that each source drive channel drives two columns of pixels or sub-pixels, so that the charging time of each column of pixels or sub-pixels is reduced by half. Or the sub-pixel charging time is insufficient, which affects the overall display brightness of the OLED
[0004] For the above-mentioned existing OLED driving methods, the number of source driving channels and the charging time are difficult to balance, and no effective solution has been proposed.

Abstract

The invention provides an OLED, an OLED drive array and a charging method of the OLED drive array. In the drive array, every two pixel lines are provided with three line electrodes and three column electrodes; each pixel or sub-pixel is connected with one line electrode and one column electrode; the three line electrodes are sequentially started according to a set sequence; one or more of the three column electrodes are sequentially started according to a set combination and sequence and used for charging the pixels or sub-pixels. Every two pixel lines are provided with three line electrodes, there is no need to configure a source electrode drive channel for each line electrode, and the number of source electrode drive channels can be reduced; under the condition that the number of the source drive channels is small, the charging time of each pixel or sub-pixel is guaranteed, then the overall brightness of an OLED display screen and the accuracy of color display of the OLED display screen are guaranteed, and color display deviation and the non-ideal effect of the display screen caused by too short a charging time are avoided.

Description

technical field [0001] The invention relates to the field of display technology, in particular to an OLED, an OLED driving array and a charging method thereof. Background technique [0002] FULL HD (Full High Definition) refers to a display standard with a physical resolution up to 1920×1080, including 1080i and 1080P; among them, i (interlace) stands for interlaced scanning; P (Progressive) stands for progressive scanning; therefore , 1080P has better picture quality and fineness than 1080i. [0003] In the application of AM OLED (Active Matrix Organic Light Emitting Diode, Active Matrix Organic Light Emitting Diode) to realize FULL HD, usually, each source drive channel in OLED drives a column of pixels or sub-pixels; however, it is limited by the structure of OLED itself , in order to reduce the number of source drive channels, data selector Mux is sometimes used, so that each source drive channel drives two columns of pixels or sub-pixels, so that the charging time of e...
