A display module includes a display panel in which a plurality of pixels each including a plurality of sub-pixels are disposed on a plurality of row lines; and a driver. The driver is configured to set a PWM data voltage to the plurality of sub-pixels included in the plurality of row lines in a row line sequence, apply a sweep signal, which is a voltage signal sweeping between two different voltages, to sub-pixels among the plurality of sub-pixels that are included in at least some consecutive row lines among the plurality of row lines in the row line sequence, and drive the display panel to cause the sub-pixels included in the at least some consecutive row lines to emit light based on the PWM data voltage in the row line sequence.

In one embodiment, a computing system may determine a group of subpixels, that are associated with different color channels, within a display region of a display. The system may determine a micro-pixel corresponding to a basic unit shape configured to evenly divide the display region and each subpixel. The system may represent the display region as a group of micro-pixels and each subpixel as a combination of one or more micro-pixels in the group of micro-pixels. The system may determine a constraint for each color channel of the display region based on the group of micro-pixels. The constraint may constrain the micro-pixels associated with a same subpixel to have a same color value. The system may generate, based on an optimization process using the constraint, a filter for the display region. The filter may be configured to adjust image pixel values to be displayed by the group of subpixels.

An organic light emitting display device and a driving method thereof are disclosed. The display device has sub-pixels of multiple colors. In one aspect, the organic light emitting display device detects sub-pixels which are positioned at the edges of the panel. Data for the sub-pixels on the edges are reduced so that colors on the edges are less observable.

Systems and methods are provided to compensate image data for display on a curved display. A pixel uniformity compensation factor may be applied based on a pixel uniformity compensation factor map that is calibrated to the display panel while the display panel has a flat shape, and a panel curvature compensation factor may be applied when the image content is to be displayed while the display panel has a curved shape. The panel curvature compensation factor may be based on a panel curvature compensation factor map that is calibrated to the display panel after the display panel is bent from the flat shape to the curved shape.

A display device includes a display panel, a driver, a detector, and an acquisition part. The driver drives the display panel based on a video signal. The detector obtains a first detection value by detecting reflective light from reflective media, which occurs when ambient light is irradiated to reflective media, while obtaining a second detection value by detecting reflective light from reflective media, which occurs when the display panel irradiates its display light to reflective media. The driver corrects a drive value for the display panel such that the second detection value approaches the first detection value or such that the chromaticity represented by the second detection value approaches the chromaticity represented by the first detection value, and therefore the acquisition part acquires information concerning the color temperature of ambient light based on the corrected drive value.

An electronic device includes a display panel. The display panel includes a number of pixels, each of which includes a driving thin-film-transistor (TFT) and a light-emitting diode. Compensation circuitry external to the display panel 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.

A display provides increased contrast and resolution via first LCD panel energized to generate an image and a second LCD panel configured to increase contrast of the image. The second panel is an LCD panel without color filters and is configured to increase contrast by decreasing black levels of dark portions of images using polarization rotation and filtration. The second LCD panel may have higher resolution than the first LCD panel. A half wave plate and/or film is placed in between the first and the second panel. The panels may be directly illuminated or edge lit, and may be globally or locally dimmed lights that may also include individual control of color intensities for each image or frame displayed.
