Embodiment 1
[0025] Such as figure 1 As shown, this embodiment provides a method for setting a Gamma curve, which is used for an OLED display panel. The OLED display panel includes sub-pixels of the first color, that is, if the OLED display panel includes three sub-pixels of red, green, and blue, and the first color The sub-pixel can be a sub-pixel of any color among red, green and blue, and the method includes:
[0026] S101. Acquire a first brightness of a sub-pixel of a first color under a first voltage.
[0027] Wherein, the "first voltage" mentioned here is a driving voltage that can make the sub-pixels of the first color emit light, so it can make the sub-pixels of the first color generate a specific first brightness. Specifically, one or more images of the gray scale of the OLED display panel may be collected according to the optical collection device, and then the first brightness of the first color sub-pixel under the first voltage may be obtained according to these displayed ima...
Embodiment 2
[0032] Such as figure 2 As shown, this embodiment provides another method for setting a Gamma curve, which is used in an OLED display panel, and the OLED display panel includes sub-pixels of a first color and sub-pixels of a second color. An OLED display panel generally includes three sub-pixels of red, green and blue, and the sub-pixel of the first color may be a sub-pixel of any color among red, green and blue. And the second color sub-pixel is a sub-pixel of any color except the first color sub-pixel, if the first color sub-pixel is a red sub-pixel, then the second color sub-pixel can be a blue sub-pixel; and if there is The sub-pixels of other colors may be sub-pixels of the third color or sub-pixels of the fourth color, etc., for example, the sub-pixels of the third color here may be green sub-pixels.
[0033] The Gamma curve setting method includes:
[0034] S201. Acquire a first correspondence relationship, where the first correspondence relationship represents a cor...
Embodiment 3
[0058] This embodiment provides another Gamma curve setting method, which is similar to the Gamma curve setting method in Embodiment 2. The setting method in this embodiment is different from steps S201 and S204 in Embodiment 2.
[0059] In step S201, further comprising: acquiring a second correspondence relationship, the second correspondence relationship represents the correspondence relationship between the voltage applied to the luminescent material forming the second color sub-pixel in the OLED display panel and its brightness.
[0060] Wherein, that is to say, the second corresponding relationship between the applied voltage and the brightness can be obtained by testing the luminescent material forming the sub-pixel of the second color.
[0061] Step S204 can be replaced by the following steps:
[0062] S3041. Acquire the second brightness of the second color sub-pixel under the second voltage.
[0063] Wherein, the "second voltage" mentioned here is a driving voltage ...
