摘要： A device comprises an image sensor having a group of pixels, wherein each pixel of the group of pixels comprises a microlens located on top of the pixel, the microlens being configured to transmit light to the pixel. The device further comprises at least one optical element, wherein each pixel of the group of pixels is covered with an optical element. The optical element comprises two transparent electrode layers aligned with the covered pixels, and a material between the two transparent electrode layers, the material being configured to change its refractive index when a voltage is applied over it, wherein the device is configured to control the transmission of the light to the covered pixels by varying the voltage of the electrode layer being aligned with the covered pixels. The invention also relates to a method and to a method for manufacturing an image sensor.

摘要： The specification and drawings present a new method, apparatus and software product for dynamically adjusting a color gamut of a display (e.g., a field sequential color display) and further adjusting a luminance of the display in an electronic device by adjusting and turning on field duties of primary colors. During each color field, the other primary colors of light sources supporting the display can be turned on at their respective fractions of their color field. These fractions can be continuously tunable in order to control the color coordinate of each primary color dynamically thus adjusting the color gamut and the luminance of the display.

摘要： An apparatus includes a sample-and-hold display with a plurality of transmissive aperture holes, and an electroluminescent backlight source with a plurality of delimited emissive areas. A dedicated delimited emissive area is associated to each transmissive aperture hole of the sample-and-hold display. A display control component updates the sample-and-hold display with a predetermined refresh rate. A backlight control component activates different portions of the electroluminescent backlight source sequentially, each portion comprising a plurality of the emissive areas.

摘要： A combined input/output device having a display mode in which it operates as a matrix display and sensing mode in which it receives optical input, comprising multiple picture element circuits arranged as a matrix display and multiple optical sensors arranged as a sensor matrix. The optical sensors and pixel circuits are integrated on the same substrate and the control lines used for controlling the pixel circuits are advantageously re-used for controlling the optical sensors. A plurality of optical sensors are enabled at a time, thereby allowing for the discrimination of inputs by gesture.
