Patent number: 10663778Abstract: This disclosure relates to a liquid crystal display and a display device. A plurality of photosensitive detectors is arranged in the frame region of the liquid crystal display panel. Light intensity distribution in the display region is estimated by a light intensity estimation module based on the light intensity detected by each photosensitive detector. Light intensity in a position corresponding to each light emitting pixel of the backlight source is determined based on the light intensity distribution in the display region estimated by the light intensity estimation module. Depending on the determined light intensity in a position corresponding to each light emitting pixel of the backlight source, luminance of the light emitting pixel in this corresponding position is controlled by a backlight driving circuit.Type: GrantFiled: July 21, 2016Date of Patent: May 26, 2020Assignee: BOE TECHNOLOGY GROUP CO., LTD.Inventors: Chengqi Zhou, Hong Wang, Yifang Chu, Chulgyu Jung, Shou Li

Patent number: 10665181Abstract: An electronic device may be provided with a display. The display may include a backlight having an array of locally dimmable light sources. Control circuitry may provide control signals to the backlight to produce light at different brightness levels. When the brightness level is below a threshold, the control circuitry may use pulse-width-modulation control signals to control the light sources in the backlight. When the brightness level is above the brightness threshold, the control circuitry may use analog control signals to control the light sources in the backlight. The control circuitry may adjust the threshold to achieve different dimming ranges for different brightness settings. A low brightness setting, for example, may have a lower threshold and lower dimming range than a high brightness setting, which may help produce darker darks when the display operates in a low brightness setting.Type: GrantFiled: February 27, 2018Date of Patent: May 26, 2020Assignee: Apple Inc.Inventors: Marc Albrecht, Teun R. Baar, Nicolas P. Bonnier, Sean Chang, ByoungSuk Kim, David S. Zalatimo
