Embodiment Construction
[0042] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0043] A kind of OLED module Gamma adjustment method based on multi-target correlation mathematical model provided by the present invention comprises the following steps:
[0044] 1) Establish the objective function:
[0045] minf lvm (R,G,B)≤γ ERROR ,minf lvm =∣γ m -2.2∣ (1)
[0046] min f xm (R,G,B)≤X ERRORm ,minf xm =∣X m -X sm ∣ (2)
[0047] min f ym (R,G,B)≤Y ERRORm ,minf ym =∣Y m -Y sm ∣ (3)
[0048] where minf lvm (R, G, B) means that the brightness value of the binding point m of the module conforms to the function of the Gamma2.2 curve, and the variable is the R, G, B register value corresponding to the binding point m of the module, γ ERROR is the γ target error corresponding to the brightness value, γ m is the γ corresponding to the actual brightness value of the binding point m; min f xm (R, G, B) means...
