Two extended embedded Display Port displays may be enabled by using a single set of panel power sequencing (PPS) signals from a chipset to enable the two embedded Display Port panels. To enhance the user experience, the backlight module brightness is controlled by making use of a pin available on a system on a chip (SOC) and modification of drivers. This helps to save power when only one panel is used. When both panels are used simultaneously, power savings can be achieved by using backlight control signals.

The present disclosure relates to a method for driving an organic light emitting display device, a driving controller, and a display device. When startup detection is required to be performed on the display compensation parameter of the organic light emitting display device, the startup detection is performed on the display compensation parameter of the organic light emitting display device to obtain a new compensation parameter value, and startup compensation display is performed based on the new compensation parameter value. When shutdown detection is required to be performed on the display compensation parameter of the organic light emitting display device, the shutdown detection is performed on the organic light emitting display device to obtain an updated compensation parameter value, and the updated compensation parameter value is stored.

Embodiments of the present disclosure provide an erasing unit for image sticking in a liquid crystal display device, a control method thereof and a liquid crystal display device. A first controlling signal may be generated by dividing a voltage at a DC power supply terminal. A controlling circuit may output a second controlling signal and a third controlling signal in responding to the voltage of the first controlling signal being smaller than or equal to a reference voltage. A charging and discharging circuit may discharge under the control of the second controlling signal and output a high-level voltage signal to an outputting circuit. The outputting circuit may supply the high-level voltage signal outputted by the charging and discharging circuit to TFTs in the liquid crystal display device, controlling the TFTs to be turned on.

Advanced display devices are integrated into glasses so that they look and feel more like normal glasses. They are based on pupil replication using multiple, small projectors. A number of projectors are embedded in the eyeglasses, for example embedded in the rim of the eyeglasses or in a periphery of the lens. The projectors generate (partial) images based on a common image to be displayed to the user. These images are optically coupled through the lens, for example using waveguide coupling, to different display windows in the lens. The display windows couple the images out of the lens and towards the user's eye.

The present embodiment relates to a technology for driving a display device, and provides a technology for adjusting the full-scale range (FSR) of an analog-to-digital converter according to a mode when sensing a pixel.

A blur eliminating circuit and a display device are provided. The blur eliminating circuit includes a detection unit and a control unit. The detection unit generates a control signal after detecting and determining that the display device is shut down. The control unit controls a gate low voltage level outputted from a gate driving unit of the display device to be a predetermined voltage level according to the control signal, and thus turns on an active switch of the display device, thereby speeding up a discharging of a liquid crystal capacitor and a storage capacitor of the display device, and eliminating a shutdown blur phenomenon.
