Increasing resolution of liquid crystal displays may result in small distances between adjacent liquid crystal display pixels. This tight pixel spacing may reduce transmission through the liquid crystal display pixels and may result in cross-talk between the liquid crystal display pixels. To increase transmission and, correspondingly, display efficiency, a reflective layer may be included in the liquid crystal display. The reflective layer recycles backlight that may otherwise be absorbed, improving transmittance and efficiency. To reduce color shift and color mixing caused by cross-talk, the pixels may have their pixel electrodes arranged in a zigzag layout. Each pixel electrode may have a height that is less than or equal to the total height of the pixel divided by two. The pixel electrodes in a given row are also alternatingly coupled to first and second gate lines. This zigzag layout results in an increased distance between adjacent pixel electrodes, mitigating pixel cross-talk.

Pixel layouts for electronic device displays

Certain embodiments are directed to techniques (e.g., a method, an apparatus, and non-transitory computer readable medium storing code or instructions executable by one or more processors) for mitigating the flicker on the displays at low driving frequencies due to drops of the voltage holding ratio of the materials for the display. The techniques to compensate for flicker in a liquid crystal display can include generating a dynamic waveform for the backlight of the display. The dynamic waveform can be synchronized with the driving rate of the liquid crystal display such that the luminosity of the backlight increases during periods when the voltage-holding ratio drops in the materials of the display. In this way, a liquid crystal material can be utilized in a display to generate reduced power consumption with liquid crystal rate minimizing the flicker in response to the drops of the voltage-holding ratio.
