A timing controller capable of communicating with a host via a Mobile Industry Processor Interface (MIPI) interface and communicating with a display via a display interface, includes a detection circuit that detects whether at least one of the MIPI interface and the timing controller is operating normally, and generates a detection signal, and an interrupt generation circuit that transmits the detection signal as an interrupt to the host via an exclusive line.

Timing controller, display system including the same, and method of use thereof

A method of operating a timing controller, which communicates with a host through a mobile industry processor interface (MIPI) and communicates with a display panel module through a display interface, is provided. The method includes storing image data compressed by one of the host and the timing controller in a frame memory, decompressing the image data stored in the frame memory, and performing panel self-refresh on the display panel module using the decompressed image data.

An operation method of a display driver includes generating a count value by counting a period of a synchronization signal related to a synchronization packet received from a host, receiving a mode change command from the host, the mode change command indicating a change from a video mode transmitting first image data to a display by bypassing a frame memory to a command mode transmitting second image data to the display through the frame memory, and generating an internal synchronization signal having a period substantially equal to the period of the synchronization signal by using the count value based on the mode change command after a last pulse of the synchronization signal is generated. A time interval between the last pulse and a first pulse of the internal synchronization signal is equal to the period of the synchronization signal.

A method and circuit for controlling the brightness of a backlight in a display device. The circuit comprises a backlight brightness selecting block that measures the brightness of ambient light and selects brightness information of the backlight based on the measured brightness of the ambient light. An image processing block performs image processing on received image signal based on the measured brightness of the ambient light, and calculates an image processing gain of the received image signal based on the result of image processing and the received image signal. A backlight adjusting unit controls the brightness of the backlight based on the selected backlight brightness information and the image processing gain.

Method and apparatus for controlling backlight in display device

A timing controller to reduce a flicker in a display device is provided. The timing controller includes a line pattern detector and a frame pattern detector. The line pattern detector divides received data into a plurality of unit blocks and detects a line polarity of each of a plurality of horizontal lines included in each of the unit blocks. The frame pattern detector generates a polarity control signal to control a data inversion method based on a frame image pattern detected based on line polarities of the respective horizontal lines.

A liquid crystal display capable of being minimized, in which a backlight assembly has a light source portion for generating light, a liquid crystal display panel receives the light from the backlight assembly to display images. A mold frame for sequentially accepting the backlight assembly and liquid crystal display panel is formed to be gradually thinner as further advancing from a first side of accepting to place the light source portion toward a second side opposing to the first side. Also, a chassis coupled to be opposite to the mold frame for closely fixing the backlight assembly and liquid crystal display panel to the mold frame is formed to be gradually thinner as further advancing from the first side of accepting to place the light source portion toward the second side opposing to the first side. Thus, the liquid crystal display can be slimmed.

Liquid crystal display and an information processing apparatus having the same

An integrated circuit may include an operation amplifier, a first capacitor, a plurality of second capacitors, and/or a switching circuit. The operational amplifier may have a first input terminal, a second input terminal, and/or an output terminal. The first capacitor may have a first terminal and a second terminal. The second terminal of the first capacitor may be connected to the first input terminal of the operational amplifier. The plurality of second capacitors may each have a first terminal and a second terminal. The second terminal of each of the second capacitors may be connected to the second input terminal of the operational amplifier. The switching circuit may include a plurality of switches configured to switch in response to a plurality of switching signals. The switching circuit may be configured to transmit a reference voltage to the first terminal of the first capacitor and the first terminals of the second capacitors and/or connect the first input terminal of the operational amplifier to the output terminal of the operational amplifier during a first period. The switching circuit may be configured to isolate the first terminal of the first capacitor from the reference voltage, transmit a voltage selected from at least two selection voltages to the first terminals of the second capacitors, and/or connect the first terminal of the first capacitor to the output terminal of the operational amplifier during a second period.
