Abstract
An optical compensation method for a display panel, an optical compensation device for a display panel, a display method for a display panel, a display device, and a storage medium are disclosed. The optical compensation method for a display panel includes: acquiring a pre-stored compensation parameter of the display panel; acquiring a current brightness level of the display panel; adjusting the pre-stored compensation parameter based on the current brightness level to obtain an adjusted compensation parameter; and compensating a display data signal of the display panel based on the adjusted compensation parameter.
Claims17
An optical compensation method for a display panel, comprising:
- obtaining a pre-stored compensation parameter of the display panel;
- obtaining a current brightness level of the display panel;
- adjusting the pre-stored compensation parameter based on the current brightness level to obtain an adjusted compensation parameter;
- and
- compensating a display data signal of the display panel based on the adjusted compensation parameter,
- wherein a calculation formula for compensating the display data signal of the display panel based on the adjusted compensation parameter is expressed as:
- Y=aX+b2,
- where Y represents a compensated pixel voltage, X represents an initial pixel voltage of the display panel, a represents a first optical compensation parameter, and b2 represents an adjusted compensation parameter and is determined based on the current brightness level of the display panel,
- wherein the adjusted compensation parameter is expressed as:
- b2=b1*c
- where b1 represents a second optical compensation parameter, c represents an offset-scalar and is determined based on the current brightness level of the display panel.
An optical compensation device for a display panel, comprising:
- a compensation parameter acquisition circuit, which is configured to acquire a pre-stored compensation parameter of the display panel;
- a brightness level acquisition circuit, which is configured to acquire a current brightness level of the display panel;
- a compensation parameter adjustment circuit, which is configured to adjust the pre-stored compensation parameter based on the current brightness level to obtain an adjusted compensation parameter;
- and
- a compensation circuit, which is configured to compensate the display data signal of the display panel based on the adjusted compensation parameter,
- wherein a calculation formula for compensating the display data signal of the display panel based on the adjusted compensation parameter is expressed as:
- Y=aX+b2,
- where Y represents a compensated pixel voltage, X represents an initial pixel voltage of the display panel, a represents a first optical compensation parameter, and b2 represents an adjusted compensation parameter and is determined based on the current brightness level of the display panel,
- wherein the adjusted compensation parameter is expressed as:
- b2=b1*c
- where b1 represents a second optical compensation parameter, c represents an offset-scalar and is determined based on the current brightness level of the display panel.
