Visual angle could be provided as intersecting the direction in 45 ° with the normal of display screen.Subsequently, it can be regarded according to current visual angle and preset reference
The comparison result at angle converts to preset reference coefficient, using scaling results as penalty coefficient corresponding with current visual angle.
In practical applications, the ratio at penalty coefficient and visual angle can be made to fix, using this fixed proportion come to pre-
If calibration coefficients convert, to be compensated coefficient.It is also possible that the change rate one of the change rate and penalty coefficient at visual angle
It causes, penalty coefficient is determined according to the change rate at visual angle.

When pixel includes red sub-pixel, blue subpixels and green sub-pixels, the preset reference coefficient can also include red
Calibration coefficients, blue reference coefficient and green calibration coefficients.
Step 122, according to the subtense angle, be based on the preset reference coefficient, determine for son in the display pixel
The penalty coefficient of pixel.
In practical applications, preset reference coefficient can be changed according to the ratio at subtense angle and preset reference visual angle
It calculates, and using scaling results as penalty coefficient.
Optionally, as an example, the penalty coefficient of each sub-pixel can be determined by following sub-step.
First, the product for obtaining the ratio and the preset reference coefficient of the red sub-pixel, multiplies as red coefficient
Product；The product for obtaining the ratio and the preset reference coefficient of the blue subpixels, as blue coefficient product.
However, according to the preset reference coefficient of the red sub-pixel and the red coefficient product, the red is obtained
The penalty coefficient of sub-pixel；According to the preset reference coefficient of the blue subpixels and the blue coefficient product, obtain described
The penalty coefficient of blue subpixels.
By red sub-pixel and blue subpixels colour cast and visual angle relevance just on the contrary, sub-pixels are sent out
Red light brightness decay under big visual angle is sent out with respect to other sub-pixel emitted light brightness decay biggers, blue subpixels
Go out the blue ray brightness decay smaller of brightness decay with respect to other sub-pixel emitted lights under big visual angle so that OLED is aobvious
Show that picture shown by device is partially blue under partially red, big visual angle under small angle.It can be by the preset reference system of the red sub-pixel
Number and the red coefficient product addition, and using result of calculation as the penalty coefficient of the red sub-pixel；By the blue
The preset reference coefficient of sub-pixel subtracts each other with the blue coefficient product, and using result of calculation as the benefit of the blue subpixels
Repay coefficient.
Finally, according to the penalty coefficient of the red sub-pixel and blue subpixels, the benefit of the green sub-pixels is determined
Repay coefficient.
It, can be according to display pixel since there are relevances with visual angle change for red sub-pixel and the colour cast of blue subpixels
The penalty coefficient of the required red and red sub-pixel and blue subpixels to be formed for mixing light and determining is counter to be pushed away
Go out the penalty coefficient of green sub-pixels so that the last display effect for forming mixing light can be consistent.
Optionally, as an example, can also penalty coefficient be determined using other technologies mode, such as：It can be
Before not carrying out luminance compensation, relational graph of the brightness of display screen relative to visual angle is determined, test the multiple visual angles of multiple spot on a display screen
Under red, green and the brightness of blue picture take the average value of its brightness as luminance reference, according to red in this relational graph
Color, the difference that green reduces coefficient with the brightness of blue picture calculate corresponding penalty coefficient.For example, under some visual angle
Red luma reduces coefficient then can be as its penalty coefficient under this visual angle.
Step 103, according to the penalty coefficient, adjust the brightness of the sub-pixel emitted light.
After determining penalty coefficient, sub-pixel institute in each display pixel can be adjusted line by line or by column according to penalty coefficient
Display screen can also be divided into several blocks by the brightness to emit beam, by the brightness of sub-pixel in block adjustment display pixel.
