Abstract

An LCD device includes a transmissive LCD panel assembly, a backlight assembly for supplying light to the LCD panel assembly, and a selective reflection film provided between the backlight assembly and the LCD panel assembly. A display region of the LCD has a low-resolution area and a high-resolution area, and a pixel formed in the low-resolution area that is larger than a pixel formed in the high-resolution area.

Claims (18)

1. A display device, comprising:

a low-resolution area comprising a first plurality of data lines and a first plurality of gate lines to form a first plurality of pixels; and

a high-resolution area comprising a second plurality of data lines and a second plurality of gate lines to form a second plurality of pixels, non-overlapping with the first plurality of pixels,

wherein the low-resolution area and the high-resolution area are configured such that the gate lines of the low-resolution area run perpendicularly to the gate lines of the high-resolution area and the data lines of the high-resolution area run perpendicularly to the data lines of the low-resolution area,

wherein each of the pixels of the first plurality of pixels of the low-resolution area is larger than each of the pixels of the second plurality of pixels in the high-resolution area,

wherein each of the second plurality of data lines of the high-resolution area terminates at a first gate line of the first plurality of gate lines of the low-resolution area,

wherein the gate lines of the low-resolution area are driven by a low-resolution gate driver, the gate lines of the high-resolution area are driven by a high-resolution gate driver that is separate from the low-resolution gate driver, and the data lines of the low-resolution area and the data lines of the high-resolution area are driven by a single driving chip, and

wherein the single driving chip is connected to the data lines of the high-resolution area via a second access part that is provided at a lowermost portion of the high-resolution area and is aligned parallel to the single driving chip while the single driving chip is connected to the data lines of the low-resolution area via a first access part that is aligned perpendicular to the single driving chip and is provided to a lateral side of the low-resolution area.

2. The display device of claim 1 , wherein each of the pixels of the first plurality of pixels of the low-resolution area is about three times as large as each of the pixels of the second plurality of pixels in the high-resolution area.

3. The display device of claim 2 , wherein a matrix of pixels formed in the low-resolution area corresponds to a matrix of pixel groups formed in the high-resolution area, each pixel group consisting of red, green and blue pixels and being represented as a dot in the high-resolution area.

4. The display device of claim 3 , wherein only data lines for supplying image signals to green pixels of the high-resolution area extend up to the low-resolution area.

5. The display device of claim 1 , wherein the low-resolution area exhibits only white and black.

6. The display device of claim 1 , additionally comprising a plurality of monochrome areas, each of the plurality of monochrome areas being low-resolution areas and exhibiting only one color, wherein each of the plurality of monochrome areas exhibits a different color from the other of the plurality of monochrome areas.

7. The display device of claim 6 , wherein at least one of the plurality of monochrome areas is comprised of pixels that each have two kinds of color filters.

8. The display device of claim 1 , wherein:

the first access part is provided at the right of the low-resolution area, and

the second access part is provided at a lowermost portion of the high-resolution area.

9. The display device of claim 1 , wherein a first data line of the first plurality of data lines of the low-resolution area is connected to the first plurality of pixels, a second data line of the second plurality of data lines of the high-resolution area is connected to the second plurality of pixels, and the first data line is substantially perpendicular to the second data line.
