A processing system is provided. The processing system includes: a sensor module configured to obtain a first image including a first reflected view of an input object within a sensing region associated with an input surface; and a determination module configured to: determine a first position of the input object within the first image; and determine a distance of the input object from the input surface using the first position.

3D interactive system

A display module includes a display device, a pivot member, and a reflection-mirror device. The display device includes a light splitting device and a monitor for displaying first and second images arranged alternately. The light splitting device is disposed at a position corresponding to a light exit side of the monitor for splitting the first and second images along first and second splitting directions respectively. The pivot member is disposed at a side of the display device. The reflection-mirror device is connected to the pivot member to be foldably pivoted to the side of the display device. The reflection-mirror device is for reflecting the first images split along the first splitting direction in a reflection direction when being unfolded relative to the display device. The reflection direction is relatively biased toward the monitor so as to form an included angle cooperatively with a normal of the monitor.

Display module

A display device for a user to observe a stereo image through a pair of polarization glasses includes a projector, a switchable polarizer, and a sensor. The projector sequentially displays a first image, a first middle image, a second image, and a second middle image on a projection screen. The switchable polarizer is located between the projector and the projection screen and is switchable between a first mode and a second mode, so that each of the first and second images has a first or second polarization after passing through the switchable polarizer in the first or second mode and is then projected onto the projection screen. The sensor is coupled to the switchable polarizer and senses the images on the projection screen. When the sensor senses the first middle image or the second middle image, the switchable polarizer switches between the first mode and the second mode.

Display device and driving method of display device

A color adjustment method for a color sequential liquid crystal display (LCD) having at least one white light source is provided. In the color adjustment method, firstly, an original image signal is converted into a target color point located in a chromaticity diagram in a color space. Then, a modified image signal having white data is calculated according to the original image signal. Afterwards, the modified image signal is converted into a main color point located in the chromaticity diagram by using a matrix group. Then, a plurality of subfield data are calculated according to the main color point and the target color point. The subfield data are used for enabling the main color point to fall on the target color point.

An adaptive feedback control method of a field sequential color display includes converting gray-scale values of a three primary color field of an input image into gray-scale values of a new three primary color field and a dominated color field (D-field); performing sampling; performing a pixel by pixel sum operation for each separated color through color gamut conversion to obtain a color difference sum; performing a feedback control at a bit precision to obtain a minimum color difference sum; and then performing a liquid crystal/backlight synchronization step of synchronizing a liquid crystal signal and a backlight gray-scale value of the input image; or dividing the input image into a plurality of blocks; performing feedback control operations; obtaining a minimum sum in each block to serve as an optical backlight value, thereby reducing a CBU phenomenon, and minimizing or controlling the generated CBUs to reduce the operation loads.

A method for driving a display includes following steps. A display panel is divided into a plurality of bright regions and a plurality of dark regions, wherein the dark regions and the bright regions are alternately arranged so that the bright regions within the display panel are not adjacent to each other. Next, a full-color frame is divided into four sub-frames, wherein the sub-frames are matched with the four color-orders one by one. In this way, the display randomly displays the sub-frames in a frame period.
