Problems solved by technology

[0009] This FRC mode is determined considering the characteristics of the display device, but it is difficult to find the best mode for the display device
[0010] Also, whenever the operating characteristics of the display device are changed due to time and cost constraints, the FRC mode is difficult to change

Embodiment Construction

[0026] The invention will now be described in more detail with reference to the accompanying drawings hereinafter, in which preferred embodiments of the invention are also shown. However, this invention may be embodied in many different forms, and its interpretation should not be limited to the embodiments set forth herein.

[0027] In the drawings, the thickness of layers and regions are exaggerated for clarity. Like numerals designate like parts throughout. It will be understood that when an element such as a layer, region or substrate is referred to as being "on" another element, it can be directly on the other element or intervening elements may also be present. In contrast, when an element is referred to as being "directly on" another element, there are no intervening elements present.

[0028] Thus, an apparatus and method for driving a liquid crystal display according to an embodiment of the present invention will be described with reference to the accompanying drawin...

Abstract

A display device is provided, which includes: a display panel including a plurality of pixels; a memory storing a plurality of FRC data patterns; a signal controller that reads out the FRC patterns, stores the FRC patterns therein, selects one of the FRC data patterns based on input image data having a first bit number and converting the input image data into output image data having a second bit number smaller than the first bit number based on the selected FRC data pattern; and a data driver applying data voltages corresponding to the output image data supplied from the signal controller to the pixels, wherein the selection of the FRC data pattern is based on the lower bit data having a third bit number of the input image data and the frame number.

Description

technical field [0001] The invention relates to a device and method for driving a liquid crystal display. Background technique [0002] A flat panel display such as a liquid crystal display (LCD) and an organic light emitting display (OLED) includes a display panel, a plurality of drivers driving the display panel, and a controller controlling the drivers. [0003] The LCD includes: two panels having pixel electrodes and a common electrode and a dielectrically anisotropic liquid crystal (LC) layer interposed between the two panels. The pixel electrodes are arranged in a matrix, are connected to switching elements such as thin film transistors (TFTs), and are supplied with data voltages from the switching elements. The common electrode covers the entire surface of one of the two panels and is supplied with a common voltage. The pixel electrode, the common electrode and the LC layer form an LC capacitor in the circuit diagram, and the LC capacitor and the switching element c...
