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.

An OLED pixel circuit and a display apparatus comprising the OLED pixel circuit. An OLED pixel circuit comprises an OLED and driving units (TFT1, S1, C) for driving the OLED to emit light, wherein one electrode of the OLED is connected to the driving units (TFT1, S1, C). The OLED pixel circuit further comprises compensation units (R1, S2, TFT2, R2). The compensation units (R1, S2, TFT2, R2) comprises a sensing element (R1) which can sense light and convert an optical signal of the OLED into an electrical signal. The compensation units (R1, S2, TFT2, R2) compensate for currents used by the driving units (TFT1, S1, C) to drive the OLED according to the light-emitting brightness of the OLED.

An example disclosed herein determines a setting to present a presentation on a transparent display layer of a display, adjusts a transparency of a first adjustable transparency layer of the display based on the first setting to present the presentation through the first adjustable transparency layer, and adjusts a transparency of a second adjustable transparency layer of the display based on the first setting to prevent the presentation from being presented through the second adjustable transparency layer.

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.

Devices and methods for improving image quality and decreasing power consumption of an electronic display are provided. The electronic device includes a display panel including a plurality of pixels configured to display an image, and to operate at multiple refresh rates. The electronic device also includes a processor configured to instruct the display panel to transition between the multiple refresh rates based at least in part on a blur effective width of the image.

A display device includes a substrate including a display configured to display an image and a non-display area disposed on at least one side of the display area. A plurality of pixels is disposed in the display area. An organic insulating layer is disposed on the substrate. A pixel defining layer is disposed on the organic insulating layer. A sealing layer at least partially covers the display area and the non-display area and includes an inorganic material. The organic insulating layer and the pixel defining layer have a valley disposed therein. The valley is formed by removing portions of the organic insulating layer and the pixel defining layer along a circumference of the display area.
