Embodiment Construction

[0034] In order to make the technical problems, technical solutions and advantages to be solved by the present invention more clear, the following will be described in detail with reference to the accompanying drawings and specific embodiments.

[0035] figure 1 It is a large-size OLED pixel compensation circuit at this stage. The symbol A in the figure shows the data line (Data Line), and the symbol B shows the sensing line (Sense Line). The basic principle of compensation is:

[0036] Initialization stage: Turn on the Scan and Sense switches, and the Data Line is given a known voltage V data , Sense Line gives reset voltage V ref , and has V data >V ref ;

[0037] Charging stage: Turn on Scan and Sense switches, due to V data >V ref , the Driving TFT (TFT in the figure) is turned on to generate a current through the Sense switch to the capacitor C of the Sense Line sense Charging, when the voltage of Sense Line (S point) is charged to V data -V th , the Driving TFT ...

Abstract

An embodiment of the present invention provides a data processing method and device, which acquires data information of pixels in a display device, and the data information includes compensation data and pixel positions of the pixels; and determines the compensation data of the pixels according to a preset mapping relationship In the storage location of the block random access memory, wherein the block random access memory includes multiple groups of data units stored sequentially, the order in which the data units adjacent to the storage positions are taken out is adjacent, and the data units include the data units taken out in the same clock cycle A plurality of compensation data, the plurality of compensation data are sequentially stored in the block random access memory; and the compensation data is stored in a storage space corresponding to the storage location. In this way, the compensation data can be preferentially stored in a block random access memory, the storage capacity of the block random access memory can be fully utilized, and the number of used block random access memories can be reduced, thereby reducing the cost of the FPGA.

Description

technical field [0001] The present invention relates to the field of display technology, and in particular, to a data processing method and device. Background technique [0002] Large-scale organic light-emitting semiconductors (Organic Light-Emitting Diode, referred to as OLED) need compensation during the display process. During the compensation process, the driver IC (Driver IC) will return the sensing data to the timing controller (TimerController, referred to as TCON), TCON The sensing data is obtained to compensate the OLED threshold voltage and mobility to the OLED. In the process of driving and calculating the compensated OLED threshold voltage and mobility according to an algorithm, a programmable logic gate array (Field Programmable Gate Array, FPGA for short) is used for implementation. [0003] In the implementation of the algorithm, a large number of FPGA internal storage resources need to be used, namely Block RAM (Random Access Memory, RAM for short). When th...
