In order to better understand the technical solution, the technical solution will be described in detail with reference to the drawings and the specific embodiments.
Example one
Referring to fig. 1, a method for optimizing a panel display includes the steps of:
in step S10, the white balance mode is turned off.
In this embodiment, in view of the fact that the present invention needs to adjust the gamma voltage and the white balance voltage to obtain the target gamma voltage and the target white balance voltage, the white balance voltage and the gamma voltage are two mutually-assisted voltages, so that the white balance function can be turned off first when the gamma voltage is adjusted, and the gamma voltage is prevented from being interfered when the gamma voltage is adjusted.
Step S20, adjusting a gamma voltage of each preset gray scale on the display panel according to a preset gamma curve and a flicker value of the display panel to obtain a target gamma voltage, so that the gamma value of each preset gray scale is consistent with the gamma value corresponding to the preset gray scale in the preset gamma curve.
In this embodiment, after the white balance mode is turned off, a preset gamma curve is obtained, where the preset gamma curve is input by a user, and the user may generate a function program based on modeling software and then take the function program as input; after a preset gamma curve is obtained, the gamma voltage of the preset gray scale to be adjusted is determined, and a target gamma voltage is obtained, wherein the determination of the target gamma voltage is based on two conditions, the first condition is that the target gamma values corresponding to the preset gray scale in the preset gamma curve are consistent, and the second condition is that the real-time flicker value of the obtained preset gray scale is minimum.
Optionally, since the gamma voltage can only adjust the gamma value of the preset gray scale, the preset gray scales are preferably the L0 gray scale, the L1 gray scale, the L31 gray scale, the L127 gray scale, the L223 gray scale, the L254 gray scale and the L255 gray scale.
Optionally, in the preset gamma curve, the gamma value in the first preset gray scale interval is the first gamma value, the gamma value in the second preset gray scale interval is reduced from the first gamma value to the second gamma value, the gamma value in the third preset gray scale interval is the second gamma value, and the gray scale values corresponding to the first preset gray scale interval, the second preset gray scale interval and the third preset gray scale interval become larger in sequence. In this embodiment, the gamma value in the second predetermined gray scale interval is reduced in a curve attenuation manner in the process of reducing the first gamma value to the second gamma value, so as to prevent the slope of the gamma curve from being too jittered. After the target gamma voltage and the target white balance voltage are obtained and burned, the actual gamma value of the display panel can be gradual, if the slope of the actual gamma curve is too tremble, the brightness change between adjacent gray scales is too large, the gray scales are gradually changed and unsmooth, and the display effect is influenced.
Step S30, the white balance mode is turned on.
Step S40, adjusting white balance voltages of all gray scales on the display panel according to the preset gamma curve and the target gamma voltage, so that the gamma value of each gray scale is consistent with the gamma value corresponding to the gray scale in the preset gamma curve.
In this embodiment, after the white balance mode is turned on, the white balance voltage of the display panel is adjusted, so as to adjust the gamma value of each gray scale of the display panel, and the display panel after the white balance voltage adjustment has a large viewing angle and a skin color picture, so as to effectively improve the whitening distortion phenomenon.
In the technical scheme of this embodiment, the preset gamma curve is an idealized gamma curve, and the method continuously adjusts the gamma voltage and the white balance voltage of the display panel, so that the actual gamma curve of the display panel corresponds to the preset gamma curve, when the actual gamma value of each gray scale of the display panel corresponds to the gamma value on the preset gamma curve by adjusting the gamma voltage and the white balance voltage, if the actual gamma value is burned to the display panel, the large-viewing-angle skin color representation of the display panel can be effectively optimized, the distortion phenomenon of the skin color and taste picture of the display panel at the large viewing angle is reduced, and the display panel is ensured to still maintain good optical quality and taste characteristics when the display panel is obliquely viewed at the large viewing angle.
In this embodiment, referring to fig. 2, step S20 specifically includes:
step S21, obtaining a target gamma value of each preset gray scale according to the preset gamma curve.
In this embodiment, the preset gamma curve is generated based on preset gamma values corresponding to all gray scales on the display panel, that is, the panel display optimization apparatus can read the preset gamma value corresponding to any gray scale according to the curve, and thus, the target gamma value can be obtained by reading the preset gamma value corresponding to the preset gray scale.
In step S22, after the target gamma value of each preset gray scale is obtained, the gamma voltage of each preset gray scale is adjusted.
Step S23, after adjusting the gamma voltage of each preset gray scale each time, obtaining an actual gamma value of each preset gray scale.
Step S24, when the actual gamma value of each preset gray scale is consistent with the target gamma value and the flicker value of each preset gray scale is minimum, recording the current gamma voltage of each preset gray scale as the target gamma voltage.
In this embodiment, after obtaining the target gamma value, the gamma voltage of each preset gray scale may be adjusted and the actual gamma value may be detected, so as to perform comparison, and the target gamma value may be obtained when the actual gamma value of the preset gray scale is the same as or similar to the target gamma value.
Preferably, after the gamma voltage of each preset gray scale is adjusted each time, the actual brightness value of each preset gray scale is detected; and calculating the actual gamma value of each preset gray scale according to the actual brightness value of each preset gray scale.
In the technical scheme of this embodiment, the preset gamma curve is an idealized gamma curve, and the method continuously adjusts the gamma voltage and the white balance voltage of the display panel, so that the actual gamma curve of the display panel corresponds to the preset gamma curve, when the actual gamma value of each gray scale of the display panel corresponds to the gamma value on the preset gamma curve by adjusting the gamma voltage and the white balance voltage, if the actual gamma value is burned to the display panel, the large-viewing-angle skin color representation of the display panel can be effectively optimized, the distortion phenomenon of the skin color and taste picture of the display panel at the large viewing angle is reduced, and the display panel is ensured to still maintain good optical quality and taste characteristics when the display panel is obliquely viewed at the large viewing angle.
In this embodiment, referring to fig. 3, step S40 specifically includes:
step S41, acquiring a target gamma value of each gray scale according to the preset gamma curve;
step S42, after obtaining the target gamma value of each gray scale, adjusting the gamma voltage of the gray scale to the target gamma voltage.
Step S43, adjusting the white balance voltage of the gray scale, and obtaining an actual gamma value of the display.
Detecting the actual brightness value of each preset gray scale after adjusting the white balance voltage of each preset gray scale each time; and calculating the actual gamma value of each preset gray scale according to the actual brightness value of each preset gray scale. Wherein, to the acquirement of actual brightness value, can use color analyzer measurement brightness value, and then calculate gamma value, specific calculation mode is: gamma is log (Ln/255, Ln/L255), n is gray scale, Ln is the brightness value of n gray scale.
Step S44, when the target gamma voltage matches the actual gamma value, recording the white balance voltage as a reference white balance voltage, and returning to the step of adjusting the white balance voltage of the gray scale until the white balance voltage is adjusted.
Step S45, determining a target white balance voltage corresponding to the gray scale according to the reference white balance voltage.
In the technical scheme of the embodiment, after the white balance voltage of each preset gray scale is adjusted each time, the actual brightness value of each preset gray scale is detected; and calculating the actual gamma value of each preset gray scale according to the actual brightness value of each preset gray scale. Since the target white balance voltage is determined based on the actual brightness of the display panel, if a large number of target display panels to be optimized exist, the target display panels can be directly burned into the target display panel, and at this time, the actual brightness values of the target display panels are also stable, so that the success rate of batch optimization of the target display panels is improved, and therefore, the success rate of optimization of display of the target display panels can be improved.
In this embodiment, referring to fig. 4, step S45 specifically includes:
step S451, arranging the reference white balance voltages in descending order.
In step S452, the number N of the reference white balance voltages is obtained.
In step S453, when the number is an odd number, (N +1)/2 th reference white balance voltage is selected as the target white balance voltage.
In step S454, when the number is even, the nth/2 and (N/2) -1 st reference white balance voltages are selected as the target white balance voltages.
In the technical solution of this embodiment, considering that there may exist a plurality of reference white balance voltages capable of adjusting the gray scale to the target gamma value, that is, a plurality of reference white balance voltages capable of adjusting the gray scale to the target gamma value are collected, one of the reference white balance voltages may be selected as the target white balance voltage for the recording through the above steps.
Example two
Referring to fig. 5, after step S40, the method further includes:
step S50, burn the target gamma voltage and the target white balance voltage to a target display panel.
In this embodiment, the determined target gamma voltage and the target white balance voltage are programmed into the target display panel, for example: under the condition that the white balance of the display panel is closed, the Gamma voltage of the display panel is adjusted, the Gamma voltage of each binding point of the liquid crystal display is adjusted to a target Gamma value GAM2.2, and the Flicker value (Flicker) of each binding point is synchronously reduced to be the lowest by adjusting the Gamma voltage, wherein the Gamma 2.2 is maintained in the whole gray scale in the conventional white balance voltage adjusting mode; after the adjustment is completed, the white balance voltage is adjusted in a mode that the gray scale before L150 maintains Gamma 2.3, then the gray scale Gamma 2.3 between L151 and L180 is slowly reduced to Gamma 2.1, and then the full gray scales of L181 to L254(L0 and L255 have no Gamma, and are not adjusted under non-characteristic conditions) maintain the Gamma 2.1 value; the large-view-angle skin color picture of the display panel after the white balance voltage adjustment can effectively improve the whitening distortion phenomenon, and the skin color picture has reduced taste difference relative to the front-view vision at an oblique view angle; the white balance voltage and the gamma voltage adjusted by the method can be directly burned into other display panels, and the method can be popularized to production lines for mass production, does not influence the actual production capacity of a factory and reduces the production efficiency.
