Problems solved by technology

However, the lifespan of organic light-emitting diode displays has always been an important issue affecting the development of this technology
However, the compensation system used for external compensation needs to receive the life attenuation parameters detected by the timing control (timer control, TCON) module, and compensate according to the compensation data and other components, so the core chip of the TCON module is damaged The logic resource requirements are high, which not only takes up too many chip processing resources, but also increases the production cost of the device

Abstract

A data compensation system of an organic light-emitting device, including a gate driving unit and a source driving and detecting unit connected to a plurality of pixel units. The compensation data unit is connected to the source driving and detection unit, and includes a storage element storing compensation data. The control unit is connected to the gate drive unit and the source drive and detection unit, and is used for generating gate control signals and source control signals, and processing display data of multiple pixel units. The source driving and detecting unit is used to detect the display data of the plurality of pixel units, perform analog-to-digital conversion, and compensate the plurality of pixel units according to the compensation data of the compensation data unit.

Description

[Technical field] [0001] The present invention relates to the field of display technology, and more particularly to a compensation system of an organic light emitting device and a compensation method thereof. 【Background technique】 [0002] As a new type of display technology with wide application prospects, the organic light-emitting diode display has high contrast, gadgetary domain, fast response speed, and thin and many advantages. However, the problem of the life of organic light-emitting diode displays has always been an important issue affecting the development of the technology. Composition of active matrix OrganicLight Emitting Diode, AMOLED display panel thin film transistor (TFT) backplane and AMOLD pixels, there are problems with devices life attenuation, while devices life attenuation can cause display brightness Gradually decrease, or the problem of uneven brightness (MURA). [0003] To solve the problem, the compensation must be compensated to make the brightness re...
