Abstract

The invention provides a display driving circuit system. The display driving circuit system comprises a flexible circuit board, a brightness compensation memory (emura RAM) and a display driving integrated circuit. The flexible circuit board is electrically connected with the display panel. The brightness compensation memory is configured on the flexible circuit board. The display driving integrated circuit is arranged on the flexible circuit board and is provided with a rectangular structure, a first side of the display driving integrated circuit is electrically connected with the brightness compensation memory, the first side is a short side of the rectangular structure of the display driving integrated circuit, and the brightness compensation memory is arranged on the first side of the display driving integrated circuit.

Description

technical field [0001] The present invention relates to a technology of a display driving integrated circuit. More specifically, the present invention relates to a display driving circuit system with an external memory for storing brightness compensation data. Background technique [0002] Organic light-emitting diodes, as a current-mode light-emitting device, have been increasingly used in high-performance displays. Due to its self-luminous properties, compared with liquid crystal display panels, active matrix organic light emitting diodes (AMOLEDs) have many advantages such as high contrast ratio, ultra-thinness, and flexibility. However, brightness uniformity is still one of the main problems it is currently facing. To solve this problem, in addition to process improvement, brightness compensation technology has to be mentioned. [0003] The compensation method of brightness uniformity (Demura) generally uses external compensation. External compensation refers to the met...
