  • Patent number: 11823621
    Abstract: A display may have an array of organic light-emitting diode display pixels operating at a low refresh rate. Each display pixel may have six thin-film transistors and one capacitor. One of the six transistors may serve as the drive transistor and may be compensated using the remaining five transistors and the capacitor. One or more on-bias stress operations may be applied before threshold voltage sampling to mitigate first frame dimming. Multiple anode reset and on-bias stress operations may be inserted during vertical blanking periods to reduce flicker and maintain balance and may also be inserted between successive data refreshes to improve first frame performance. Two different emission signals controlling each pixel may be toggled together using a pulse width modulation scheme to help provide darker black levels.

  • Patent number: 11776297
    Abstract: This invention is related to a technical field of optical fingerprint recognition. It particularly designs a coordinate transformation method for imaging under screen, a storage medium and an electronic device. The a [sic] coordinate transformation method for imaging under screen includes steps of: calculating a coordinate system shrink coefficient; copying each luminous point in a fingerprint image to a shrunken coordinate system; and moving the entirety to the shrunken coordinate system with a relative distance between fingerprint information around a luminous point and a center of the luminous point being kept unchanged. Through coordinate transformation, restoration of the fingerprint image is guaranteed, and also pixels are guaranteed to not be lost at the same time, thereby ensuring the definition of the fingerprint image thus restored. In addition, this manner for restoring fingerprint images is simple in calculation process, fast in restoration speed, and good in quality.
