Abstract
Methods and apparatus relating to techniques to provide dynamic pixel density adjustment for display panels not driven by backlight are described. In an embodiment, logic causes a first plurality of pixels of a display panel to be turned off in response to an indication that a charge level of a power supply, coupled to supply electrical power to the display panel, has dropped below a threshold level. The display panel is not backlight drive (such as an OLED or QDOT display panels. Other embodiments are also disclosed and claimed.
Claims25
An apparatus comprising:
- logic, at least a portion of which is in hardware, to cause a first plurality of pixels of a display panel to be turned off in response to an indication that a charge level of a power supply, coupled to supply electrical power to the display panel, has dropped below a threshold level,
- wherein the display panel is not backlight driven, wherein the logic is to cause assignment of a lower resolution framebuffer for the first plurality of pixels in response to result of a capability query from the display panel, wherein the result of the capability query is to indicate whether the display panel is capable of causing the first plurality of pixels of the display panel to turn off at the display panel.
A method comprising:
- causing a first plurality of pixels of a display panel to be turned off in response to an indication that a charge level of a power supply, coupled to supply electrical power to the display panel, has dropped below a threshold level,
- wherein the display panel is not backlight driven, wherein a lower resolution framebuffer is assigned to the first plurality of pixels in response to result of a capability query from the display panel, wherein the result of the capability query indicates whether the display panel is capable of causing the first plurality of pixels of the display panel to turn off at the display panel.
One or more non-transitory computer-readable medium comprising one or more instructions that when executed on at least one processor configure the at least one processor to perform one or more operations to:
- causing a first plurality of pixels of a display panel to be turned off in response to an indication that a charge level of a power supply, coupled to supply electrical power to the display panel, has dropped below a threshold level,
- wherein the display panel is not backlight driven, wherein a lower resolution framebuffer is to be assigned to the first plurality of pixels in response to result of a capability query from the display panel, wherein the result of the capability query is to indicate whether the display panel is capable of causing the first plurality of pixels of the display panel to turn off at the display panel.
