A display apparatus includes an image processor which processes an image to display an image content; a display unit which displays thereon an image content that is processed by the image processor; and a controller which displays a user interface (UI) menu including a plurality of UI items to search the image content, as one of a two-dimensional (2D) layout by which the plurality of UI items are arranged in a 2D manner, and a three-dimensional (3D) layout by which the plurality of UI items are arranged in a 3D manner , and changes displaying the one of the layouts to display the other of the layouts according to a user's command while maintaining a continuity of the arrangement of the plurality of UI items. Accordingly, search for an image content can be efficiently performed by using a UI menu.

Display apparatus and control method thereof

An LCD groups pixels in each row into a plurality of blocks, and calculates difference in gray between every two image data applied to a pair of adjacent odd and even pixels in each block including pixels in a row for each of first to third colors. It is determined that a block is first or second dot block depending on a sign of the gray difference when a magnitude of the gray difference between the odd pixel and the even pixel in each pair in the block for at least one color is equal to or larger than a critical value. A current block in a current row and in columns is determined to be a one-dot block when the current block is the first dot block and a previous block in a previous row and in the columns is the second dot block. When the number of the one-dot blocks is a predetermined percentage of the number of the total blocks, it is determined that a one-dot pattern is generated and one-dot inversion of the LCD is changed into another inversion. In this way, a pattern generating flicker is determined and the inversion type is changed for reducing the flicker.

Liquid crystal display and driving method thereof

Methods and apparatus for efficiently directing communications are disclosed. On example entails receiving, from a mobile terminal, a communication directed to a cellular communication network, the communication being received in an alternative channel that differs from a channel of the cellular communication network. The communication is then converted for a relayed communication to the cellular communication network on behalf of the mobile terminal, the relayed communication being made through the cellular communication network.

Methods and apparatuses for adjusting backlight intensity in a display device of a computer system, and compensating with image brightness adjustments via graphics controller color-lookup table to retain a net equivalent level of brightness as perceived by the user when viewing images produced by the graphics controller on the display device

Automatic image luminance control with backlight adjustment

Light in the visible spectrum is modulated using an array of modulation elements, and control circuitry connected to the array for controlling each of the modulation elements independently, each of the modulation elements having a surface which is caused to exhibit a predetermined impedance characteristic to particular frequencies of light. The amplitude of light delivered by each of the modulation elements is controlled independently by pulse code modulation. Each modulation element has a deformable portion held under tensile stress, and the control circuitry controls the deformation of the deformable portion. Each deformable element has a deformation mechanism and an optical portion, the deformation mechanism and the optical portion independently imparting to the element respectively a controlled deformation characteristic and a controlled modulation characteristic. The deformable modulation element may be a non-metal. The elements are made by forming a sandwich of two layers and a sacrificial layer between them, the sacrificial layer having a thickness related to the final cavity dimension, and using water or an oxygen based plasma to remove the sacrificial layer.

Method and device for modulating light

Systems and methods are provided for supporting an external display on a portable device. A system on a chip (SOC) of the portable device provides a first set of graphics data to a graphics controller. The embedded graphics controller renders the first set of graphics data for output using an LCD screen integrated with the portable device. The SOC renders a second set of graphics data and provides rendered graphics data to an external display interface. The external display interface formats the rendered graphics data for output on an external, remote display.
