Generally, when the pixel voltage association table includes a visual compensation table, the pixel voltage association table includes main pixel voltages of all main pixel circuits corresponding to different viewing angles and sub pixel voltages of all sub pixel circuits corresponding to different viewing angles; the step of determining a target primary pixel voltage of the primary pixel circuit and a target secondary pixel voltage of the secondary pixel circuit in the pixel voltage correlation according to the target view angle includes: determining target main pixel voltages of all the main pixel circuits and target sub-pixel voltages of all the sub-pixel circuits in the pixel voltage association according to the target view angle; correspondingly, the step of controlling the main pixel circuit by using the target main pixel voltage and controlling the sub-pixel circuit by using the target sub-pixel voltage includes: and controlling all the main pixel circuits by using the target main pixel voltage, and controlling all the sub-pixel circuits by using the target sub-pixel voltage.
It will be appreciated that in this embodiment, each viewing angle corresponds to a pair of voltage values (a main pixel voltage and a sub-pixel voltage) for each pair of pixels (including a main pixel circuit and a sub-pixel circuit) which are used to control the main pixel circuit and the sub-pixel circuit included in the pair of pixels.
In addition, when the pixel voltage association table comprises a visual compensation table, in the visual compensation table, only a part of main pixel voltages corresponding to the main pixel circuits and a part of sub-pixel voltages corresponding to the sub-pixel circuits are included under one visual angle; the step of determining a target primary pixel voltage of the primary pixel circuit and a target secondary pixel voltage of the secondary pixel circuit in the pixel voltage correlation according to the target view angle includes: determining a selected main pixel circuit among all the main pixel circuits based on the target viewing angle and the visual compensation table; determining a selected sub-pixel circuit among all sub-pixel circuits based on the target viewing angle and the visual compensation table; determining a target main pixel voltage corresponding to the selected main pixel circuit in the visual compensation table; determining a target sub-pixel voltage corresponding to the selected sub-pixel circuit in the visual compensation table; correspondingly, the step of controlling the main pixel circuit by using the target main pixel voltage and controlling the sub-pixel circuit by using the target sub-pixel voltage includes: and controlling the selected main pixel circuit by using the target main pixel voltage, and controlling the selected sub-pixel circuit by using the target sub-pixel voltage. In the visual compensation table, the visual angle corresponding to the target visual angle is a selected visual angle, part of the main pixel circuits corresponding to the selected visual angle are selected main pixel circuits, and part of the sub-pixel circuits corresponding to the selected visual angle are selected sub-pixel circuits.
It is understood that, in this embodiment, for a viewing angle, the visual compensation table may only have the voltage of a part of the main pixel circuits and the voltage of a part of the sub-pixel circuits, the part of the main pixel circuits being the selected main pixel circuits under the viewing angle, and the part of the sub-pixel circuits being the selected sub-pixel circuits under the viewing angle; under the view angle, the voltage corresponding to the selected main pixel circuit is the target main pixel voltage, and the voltage corresponding to the selected sub-pixel circuit is the target sub-pixel voltage.
Specifically, the visual compensation table is obtained in the following manner: determining a plurality of second preset viewing angles (which may be the same as the first preset viewing angles); determining a plurality of pairs of voltages respectively corresponding to a plurality of second preset visual angles (a pair of voltages comprises a main pixel voltage and a sub-pixel voltage, and the main pixel voltage corresponding to one second preset visual angle comprises the respective voltage of all main pixel circuits of the display terminal under the visual angle); establishing a second mapping relation between a plurality of second preset visual angles and a plurality of pairs of voltages; and obtaining a visual compensation table based on a plurality of second preset visual angles, a plurality of pairs of voltages and the second mapping relation. It can be understood that, for a second preset viewing angle, multiple pairs of initial voltages need to be set, and the detection device is used to detect the display effect of the display terminal under the driving of the multiple pairs of initial voltages, and determine a pair of initial voltages with the best display effect as a pair of voltages corresponding to the second preset viewing angle.
It can be understood that, when the display effect at a second preset viewing angle is the same as the display effect at the positive viewing angle, that is, the display effect at the second preset viewing angle is also the best display effect, if the main pixel voltage and the sub-pixel voltage corresponding to a certain pair of pixels are the same as the main pixel voltage and the sub-pixel voltage at the positive viewing angle, then the pair of voltages of the pair of pixels at the second preset viewing angle may not be included in the visual compensation table, which indicates that when the positive viewing angle is converted into the second preset viewing angle by the user, the pair of voltages of the pair of pixels is not queried by the display terminal in the visual compensation table, and the pair of pixels does not need to perform voltage adjustment of the main pixel circuit and the sub-pixel circuit. That is, in some embodiments, for a certain second predetermined viewing angle, the visual compensation table only includes the voltage values of the main pixels corresponding to a part of the main pixels and the voltage values of the sub pixels corresponding to a part of the sub pixels.
