Abstract: Described herein are methods and a system to correct environmental light reflecting onto a surface of a display. An image is captured by camera which is processed as an image digital map. Light sources on the image digital map are determined based on correlated camera pixel map and display map. Light sources are on the image digital map are augmented by one or more ambient light sensors (ALS) placed on the periphery of the display. Image correction is performed based on the light sources of the image digital map.

Abstract: A low-resolution image is displayed at high resolution and power consumption is reduced. Resolution is made higher by super-resolution processing. Then, display is performed with the luminance of a backlight controlled by local dimming after the super-resolution processing. By controlling the luminance of the backlight, power consumption can be reduced. Further, by performing the local dimming after the super-resolution processing, accurate display can be performed.

Abstract: In an embodiment, a display device comprises a display panel, a light source and a controller. The display panel including pixels, a common electrode, pixel electrodes and a liquid crystal layer containing a polymer dispersed liquid crystal. The light source emits light to the display panel. The liquid crystal layer scatters light when scattering voltage is applied between the common electrode and the pixel electrodes, and transmits light when transparent voltage is applied between the common electrode and the pixel electrodes. The controller applies the transparent voltage in a first period, and applies voltage in accordance with image data in a second period.

Abstract: In a method of enhancing the appearance of a digital image on an electronic display, Ambient Light Sensor (ALS) and Screen Brightness (SB) inputs are combined with a calibration input 12 to generate a first strength parameter 22, including an alpha component that is dependent only upon the properties of the display. Then a further, content-based input 24 is also combined to generate a second strength parameter 26, including a beta component that is dependent only upon a content type, or a content quality, or both.
