Abstract:
A display device that achieves both high detection sensitivity of the touch sensor unit and smooth input on the touch sensor unit is provided. A method for driving a display device includes a first period and a second period. The display device includes pixels, a gate driver, and a touch sensor unit. The touch sensor unit detects a touch in the first period and stops detecting a touch in the second period. The gate driver supplies signals to some of the pixels and does not supply signals to the other pixels in the second period.
Abstract:
A display has rows and columns of pixels (22). A data line (Dn) in each column provides image data signals to the pixels of that column. Each row has first and second control lines (select[m], monitor[m]) coupled to the gates of first and second respective transistors (SE, MO) in each pixel. A third transistor in each pixel servea as a drive transistor (DR) and is coupled in series with a light-emitting diode (30) between positive and ground power supply voltages (VDD, VSS). A display driver circuitry in the display characterizes each of the light-emitting diodes in a column using the data line in an adjacent column from that light-emitting diode. Each of the drive transistors in a column is characterized using the data line in that column and the data line in an adjacent column.
Abstract:
An electronic device 10 includes a display panel 18. The display panel 18 includes a number of pixels 62, each of which includes a driving thin-film-transistor (TFT) and a light-emitting diode. Compensation circuitry 152 external to the display panel 18 applies offset data to pixel data for each pixel of the plurality of pixels before the pixel data is provided to the plurality of pixels.
Abstract:
An apparatus includes a graphics pipeline and a pixel data reordering module. The graphics pipeline is configured to generate a plurality pieces of pixel data of a frame. The plurality pieces of pixel data of the frame are associated with a first order in which the plurality pieces of pixel data of the frame are to be provided to a display panel having an array of pixels. Each piece of pixel data of the frame corresponds to one pixel of the array of pixels. The array of pixels are divided into a plurality of groups of pixels. The pixel data reordering module is configured to cause the plurality pieces of pixel data of the frame to be obtained by the display panel in a second order. The second order is determined based on at least a manner in which the array of pixels are divided into the groups of pixels.
