Embodiment Construction

[0039] In order to further illustrate the technical means adopted by the present invention and its effects, the following describes in detail in conjunction with preferred embodiments of the present invention and accompanying drawings.

[0040] see figure 1 , the present invention provides a method for processing compensation data of an OLED display panel, comprising the following steps:

[0041] Step 1. Obtain compensation data of the OLED display panel.

[0042] Specifically, the compensation data of the OLED display panel in the step 1 is data in a picture format.

[0043] Step 2. Perform n-level wavelet transform on the compensation data of the OLED display panel to obtain n-level approximation matrix, n-level horizontal detail matrix, n-level vertical detail matrix, and n-level diagonal detail matrix of the compensation data, n is a positive integer.

[0044]The n-level wavelet transformation process is to firstly perform wavelet transformation on the compensation data...

Abstract

The invention provides a compensation data processing method for an OLED display panel. By conducting wavelet transform on compensation data, discarding a detail matrix obtained through wavelet transform, only storing an approximate matrix obtained through wavelet transform, then estimating the detail matrix by means of the stored approximate matrix, reconstructing wavelet transform and conducting inverse wavelet transform to obtain compensation data again, compression and decompression of the compensation data can be achieved. System storage space occupied by the compressed compensation data is reduced greatly, so that time for data transmission and burning on a production line is shortened. Furthermore, the compressed data have a fixed compression ratio, the error between the compensation data obtained after decompression and the original compensation data is extremely small, and the display quality of the OLED display panel is not affected.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a method for processing compensation data of an OLED display panel. Background technique [0002] Flat-panel display devices have many advantages such as thin body, power saving, and no radiation, and have been widely used. Existing flat panel display devices mainly include liquid crystal display devices (Liquid Crystal Display, LCD) and organic light emitting diode display devices (Organic Light Emitting Display, OLED). [0003] Organic light-emitting diode display devices have excellent characteristics such as self-illumination, no need for backlight, high contrast, thin thickness, wide viewing angle, fast response speed, flexible panels, wide operating temperature range, and simple structure and manufacturing process. It is considered as an emerging application technology for the next generation of flat panel displays. [0004] OLED display devices generally include: a subs...
