Problems solved by technology

However, since the light-emitting element is driven to emit light for a long time during the entire picture period, it not only wastes the light-emitting time of the light-emitting element, causes power loss, but also affects the service life of the light-emitting element

Abstract

The invention provides an organic light-emitting displayer which comprises a light-emitting control circuit and a plurality of display units. The light-emitting control circuit responds to a plurality of time sequence signals and outputs a plurality of light-emitting control signals independent of one another. The enabled period of each light-emitting control signal depends on at least one of frequency and the duty ratio corresponding to the time sequence signals. The display units respectively receive the light-emitting control signals, and display corresponding pixel data according to the light-emitting control signals. Accordingly, the purpose of controlling the enabled periods of the light-emitting control signals by controlling the frequency and / or the duty ratio of the time sequence signals can be achieved, time for driving a light-emitting element to emit light during a whole frame period can be shortened, and power loss can be avoided.

Description

technical field [0001] The content of the present invention relates to a display device, and in particular to an organic light emitting display. Background technique [0002] In the prior art, organic light emitting displays (OLEDs) can be roughly divided into passive matrix organic light emitting displays (passive matrix OLEDs) and active matrix organic light emitting displays (active matrix OLEDs). Compared with passive matrix organic light emitting displays, active matrix organic light emitting displays have the advantages of low power loss, low operating voltage, and high efficiency. Therefore, active matrix organic light emitting displays have become the mainstream of organic light emitting displays. [0003] In an active matrix organic light-emitting display, a driving signal is usually generated to control the on / off state of the pixel through the gate line, and a control signal is generated to drive the light-emitting element in the pixel to emit light through the re...
