Abstract: Methods and devices employing charge removal circuitry are provided to reduce or eliminate artifacts due to a bias voltage remaining on an electronic display after the display is turned off. In one example, a method may include connecting a pixel electrode of a display to ground through charge removal circuitry while the display is off (e.g., using depletion-mode transistors that are active when gates of the depletion-mode transistors are provided a ground voltage). When a corresponding common electrode is also connected to ground, a voltage difference between the pixel electrode and common electrode may be reduced or eliminated, preventing a bias voltage from causing display artifacts in the pixel.

Abstract: A display may have a thin-film transistor (TFT) layer and color filter layer. Light blocking structures in an inactive area of the display may prevent stray backlight from leaking out of the display. The thin-film transistor layer may have a first substrate, a first black masking layer, a planarization layer, and a layer of TFT circuitry on the planarization layer. The color filter layer may have a second substrate and a second black masking layer on the second substrate. Light-cured sealant may be formed between the TFT layer and the color filter layer. Gaps may be formed in the second black masking layer to allow light to cure the sealant. At least a portion of the TFT circuitry may serve to block stray backlight penetrating through the gaps in the second black masking layer during normal operation of the display.

Abstract: Devices and methods for reducing or eliminating image artifacts are provided. By way of example, a display panel includes row common voltage (VCOM) electrodes each having a first width. The row VCOM electrodes extend along a first direction of the display panel. The display panel also includes column VCOM electrodes each having a second width. The column VCOM electrodes extend along a second direction of the display panel perpendicular to the first direction. The second width of the column VCOM electrodes may be substantially less than the first width of the row VCOM electrodes to increase a resistance of the column VCOM electrodes. By increasing the resistance of the column VCOM electrodes, image artifacts on the display panel may be prevented or eliminated.

Abstract: A thin-film transistor having a protection layer for a planarization layer. The protection layer prevents reduction of the planarization layer during an ashing process, thereby preventing the formation of a steeply tapered via hole through the planarization layer. In this manner, the via hole may be coated with a conductive element that may serve as a conductive path between a common electrode and the drain of the transistor.

Abstract: An electronic device may include a display having an array of organic light-emitting diode display pixels that produce light that forms an image. Color filter elements may be used to allow the display to present color images. Each display pixel may have a red subpixel, a blue subpixel, a green subpixel, and a white subpixel. To adjust the color coordinates of the white pixel and thereby ensure that the light from the white pixel has a desired white point, part of the white subpixel may be overlapped by an area of colored color filter material. The white subpixel may, for example have a rectangular white area within which a patch of blue color filter material may be provided to make the white light from the white subpixel more bluish than it would be without the patch of blue color filter material.
