Embodiment Construction

[0034] Reference will now be made in detail to embodiments of the present disclosure, examples of which are illustrated in the accompanying drawings. Wherever possible, the same reference numbers will be used throughout the drawings to refer to the same or like parts.

[0035] will refer to Figures 5 to 14C Exemplary embodiments of the present disclosure are described.

[0036] Figure 5 is a block diagram of a display device capable of being driven at a low speed according to an exemplary embodiment of the present invention.

[0037] Such as Figure 5 As shown, a display device capable of being driven at a low speed may be implemented as a flat panel display such as a liquid crystal display (LCD), field emission display (FED), plasma display panel (PDP), organic light emitting display, or electrophoretic display (EPD). In the following description, a liquid crystal display is used as an example of a flat panel display. Alternatively, other flat panel displays may be use...

Abstract

The invention discloses a display device capable of being driven at a low speed. Based on the Z inversion scheme, the pixels connected to the first data lines on the odd-numbered display rows of the display panel are arranged on one of the left and right sides of the first data lines, and are connected to the even-numbered lines on the display panel. The pixels of the first data line on the numbered display row are arranged on the other side of the first data line. When a mode switching control signal for switching to an interlaced low-speed driving mode is input in normal driving, where the length of one frame is set to P, the timing controller expands the length of one frame for low-speed driving to n×P, where n is a positive integer equal to or greater than 2 and the length P is allocated to each of n subframes of the one frame.

Description

technical field [0001] Embodiments of the present disclosure relate to a display device capable of being driven at a low speed. Background technique [0002] Display devices have been used in various display units such as portable information devices, office equipment, computers, and televisions. [0003] A method for reducing power consumption of a display device includes a low-speed driving technique. The low-speed driving technique changes a frame frequency (for example, a driving frequency) based on a change in the amount of data. In a stop image in which data does not change, the low-speed driving technique refreshes the screen of the display device with a frame frequency less than an input frame frequency (for example, a normal frame frequency of 60 Hz). In a moving picture in which data changes exist, the screen of the display device is refreshed with a normal driving method based on an input frame frequency. The display device may change the frame frequency in res...
