A display device and a method for driving the same are discussed. The display device includes an image processing unit, a timing controller which receives various signals through a mobile industry processor interface (MIPI) connected to the image processing unit, and a display module displaying an image under the control of the timing controller. The timing controller includes a logic block for controlling the display module, and a self-recovery block which outputs a self-command signal for escaping an abnormal state when the logic block is faced with the abnormal state due to an external environment factor.

Display device including a timing controller with a self-recovery block and method for driving the same

The present invention provides a LCD device including: a timing control unit; an oscillator which is included in the timing control unit and generates a clock frequency; a frequency divider which is included in the timing control unit and reduces the clock frequency supplied from the oscillator by dividing the clock frequency by at least 2; and a mode selection part which is included in the timing control unit and changes at least one driving mode of internal logic circuits by using the divided clock frequency supplied from the frequency divider.

Liquid crystal display device and driving method for changing driving mode thereof

A liquid crystal display includes a liquid crystal display panel having a pixel array including a first group of liquid crystal cells connected to odd-numbered gate lines and a second group of liquid crystal cells connected to even-numbered gate lines and a data driving circuit including a latch array. Each liquid crystal cell of the second group shares a data line with one liquid crystal cell of the first group adjacent to the liquid crystal cell of the second group in an extension direction of the gate lines. The latch array delays only second group data to be applied to the liquid crystal cells of the second group among digital video data for one horizontal line by about one half horizontal period in response to a data rendering control signal.
