Disclosed is a display apparatus capable of improving a sound quality through an accurate sound transmission, wherein the display apparatus may include a backlight module connected with a rear surface of a display panel, a rear structure for surrounding the backlight module, and a vibration generating device for vibrating the display panel through the backlight module, wherein the vibration generating device is fixed to the rear structure.

Display apparatus

A display device comprises a display panel including a main display region and a periphery region outside the main display region; and a panel driver connected with the display panel in the periphery region of the display panel, wherein the display panel includes an upper substrate and a lower substrate formed under a lower surface of the upper substrate, and the lower substrate is formed to expose a pad region provided on the lower surface of the upper substrate, and the panel driver is connected to the pad region provided on the lower surface of the upper substrate.

Display device

A driving method of an image display device includes detecting an amount of data change of an input image and calculating a moving speed of the input image, determining whether the image moving speed is within a preset reference range, when the image moving speed is within the reference range, driving a display screen according to an input frame frequency synchronized to the input image, and when the image moving speed is out of the reference range, down-modulating a frame frequency for displaying the input image to a frequency lower than the input frame frequency and driving the display screen according to a modulated frame frequency.

Image display device and driving method thereof

A timing controller including a memory unit configured to store image data with respect to p*q sub-pixels defined using p numbers of data lines and q numbers of gate lines, a reception unit configured to receive, from a host, (n+m)-bit image data with respect to each of two or more of the sub-pixels, a controller configured to generate pseudo control data corresponding to m-bit image data of the two or more of the sub-pixels, and an output unit configured to output n-bit image data with respect to each of the sub-pixels to a digital unit of a data driving unit, and output the pseudo control data to an analog unit of the data driving unit.

Timing controller generating pseudo control data included in control packet and N-bit image data included in RGB packet

Provided is a data driver, a driving method of the data driver, and a display device. The data driver includes a latch unit configured to store n-bit image data, wherein n&#x2265;2; a conversion unit configured to convert N-bit digital data including the n-bit image data and variable m-bit pseudo control data into an analog voltage and then output the analog voltage, wherein m&#x2265;1; and an output unit configured to output a data voltage based on the analog voltage. The data driver is capable of supplying a high image quality based on N-bit digital data with a small circuit size that is based on n-bit image data.
