Blue light compensation system and method for display

Abstract

The invention discloses a blue light compensation system for a display, and the system is used for blue light compensation of a display panel of an organic light-emitting diode display. The system comprises a gamma module; a timing module which is electrically connected with the gamma module and is used for calculating the total work time of the gamma module; and a register which is electrically connected with the gamma module and is used for registering a gamma numerical table of blue sub-pixels of the display panel, wherein the compensation design of the gamma numerical table is carried out according to the aging characteristics of a blue sub-pixel material of the display panel. The gamma module extracts the corresponding gamma value from the register according to the total work time, and calculates the drive voltage of the blue sub-pixels of the display panel according to the corresponding gamma value. The display employing the system is better in display quality. The invention also discloses a blue light compensation method for the display.

Description

technical field [0001] The present invention relates to the technical field of display display, in particular to a blue light compensation system for a display and a blue light compensation method for a display. Background technique [0002] OLED (Organic Light-Emitting Diode), the organic light-emitting diode display technology, is a self-luminous display device with an organic thin film as a light-emitting body. Its working principle is: driven by an external voltage, the electrons and holes injected by the electrodes are in the organic material The recombination releases energy and transfers the energy to the molecules of organic light-emitting substances, which are excited and transition from the ground state to the excited state. When the excited molecule returns from the excited state to the ground state, the radiative transition produces the phenomenon of luminescence.

Problems solved by technology

[0003] Although the OLED display panel has the advantages of thinness, wide viewing angle, and high contrast, due to the defect of the blue sub-pixel material (the material aging speed is fast), the blue sub-pixel has low luminous efficiency, short life, and blue sub-pixel luminous attenuation. As a result, the image quality of many OLED display panels is severely deteriorated, and color cast occurs, which makes the display quality of OLED display panels poor.
