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

The invention discloses a data compensation system of an organic light-emitting device. The data compensation system comprises a gate driving unit and a source driving and detecting unit which are connected to a plurality of pixel units, the compensation data unit is connected to the source electrode driving and detecting unit and comprises a storage element storing compensation data. The controlunit is connected to the gate drive unit and the source drive and detection unit, and is used for generating a gate control signal and a source control signal and processing display data of the plurality of pixel units. And the source electrode driving and detecting unit is used for detecting the display data of the plurality of pixel units, and compensating the plurality of pixel units accordingto the compensation data of the compensation data unit through analog-to-digital conversion.

Description

[0001] 【Technical field】 [0002] The invention relates to the field of display technology, in particular to a compensation system of an organic light-emitting device and a compensation method thereof. [0003] 【Background technique】 [0004] As a new display technology with broad application prospects, organic light-emitting diode display has many advantages such as high contrast, wide color gamut, fast response speed and thinness. However, the lifespan of organic light emitting diode displays has always been an important issue affecting the development of this technology. Both the thin film transistor (TFT) backplane and the AMOLED pixels that make up the active matrix organic light emitting diode (AMOLED) display panel have the problem of device life attenuation, and the device life attenuation will cause the display brightness to decrease. Gradual decrease, or the problem of uneven brightness (Mura). [0005] In order to solve the foregoing problems, compensation must be ...
