An overdrive system includes a compressor that compresses an input signal to result in a compressed signal; a weighting device that generates a weighted sum of a current compressed signal and a current input signal, thereby resulting in a weighted current signal; and an overdriver that performs an overdrive operation according to a previous compressed signal and the weighted current signal.

In some examples, an electronic device comprises a voltage supply circuit to provide a reference voltage usable to discharge pixels in a display device; and a scaler circuit coupled to the voltage supply circuit. The scaler circuit is to buffer first and second frames and dynamically control the voltage supply circuit to modify the reference voltage based on a frequency of the first frame differing from a frequency of the second frame.

Disclosed is a display method of a display panel. The display panel includes two display screens arranged opposite to each other, and the display method of the display panel includes: acquiring a liquid crystal response duration of each display screen upon receiving image information to be displayed; taking a display screen having a shorter liquid crystal response duration as a first display screen, and taking a display screen having a longer liquid crystal response duration as a second display screen; and driving the second display screen to display, and delaying to drive the first display screen to display. A display device and a display panel are also disclosed. The display panel of the present application has a good display effect.

Methods, systems and apparatuses may provide for technology that generates a seed value, wherein the seed value is dedicated to a position of an input pixel, generates a dithered pixel value based on the seed value and a value of the input pixel, and conducts a scan-out of the dithered pixel value to a display panel. In one example, the technology generates an intermediate value based on the seed value and one or more fixed constants and generates a pseudo random number based on the intermediate value and a programmable constant, wherein the dithered pixel value is generated based on the pseudo random number and the value of the input pixel.

Display filters, including color filters, can be enabled in collaborative environments. When a user of an end user device desires to have a color filter applied, a windowing system or other source of graphics data can render a frame via a graphics driver. Once the frame is rendered, the graphics driver can enable a collaboration tool to capture the frame and share it via a collaboration solution. Separately from the rendering of the frame, the windowing system can leverage a color filter module to directly apply a color filter to the frame. Once the color filter is applied, the windowing system can cause the frame to be displayed locally. Because the graphics driver is not used to apply the color filter, the color filter will not be applied to any frame that the collaboration tool captures and shares.
