Abstract

There is disclosed a liquid crystal display for a mobile phone that is adaptive for minimizing horizontal flicker. A liquid crystal display for a mobile phone according to an embodiment of the present invention includes a liquid crystal display panel where liquid crystal cells are each arranged in a matrix at each intersection part of data lines and gate lines; and a driver supplying a data signal to the data line and, in addition, supplying a gate signal to the adjacent gate lines in a different direction from each other.

Claims (37)

1. A liquid crystal display for a mobile phone, comprising:

a liquid crystal display panel;

a plurality of gate lines and data lines crossing each other;

liquid crystal cells formed at each crossing of data lines and gate lines; and

a driver supplying a data signal to the data lines, said driver supplying a gate signal to each of adjacent gate lines in a different direction from each other; and

a plurality of signal lines, each signal line commonly connected to interface pads and to input bumpers of the driver,

wherein the liquid crystal display panel is driven by a line inversion method.

2. The liquid crystal display for a mobile phone according to claim 1 , wherein the liquid crystal display panel includes:

a first signal line formed on one side of the liquid crystal display panel to be connected to an odd-numbered gate line;

a second signal line formed on the other side of the liquid crystal display panel to be connected to an even-numbered gate line; and

a third signal line connected to the data line.

3. The liquid crystal display for a mobile phone according to claim 2 , wherein the driver includes:

a film adhered to the liquid crystal display panel;

a data drive circuit mounted on the film for supplying a data signal to the third signal line; and

a gate drive circuit mounted on the film for supplying a gate signal to the first and second signal lines.

4. The liquid crystal display for a mobile phone according to claim 1 , wherein a distance between a pixel electrode of a liquid crystal cell and a pixel electrode of an adjacent liquid crystal cell is approximately 0.7 μm.

5. A liquid crystal display for a mobile phone comprising:

a liquid crystal display panel;

a plurality of gate lines and data lines crossing each other;

liquid crystal cells formed at each crossing of data lines and gate lines;

a driver supplying a data signal to the data lines, said driver supplying a gate signal to each of adjacent gate lines in a different direction from each other; and

signal lines, each signal line commonly connected to interface pads and to input bumpers of the driver.

6. The liquid crystal display for a mobile phone according to claim 5 , wherein a resistance of the signal line is below about 10Ω.

7. A method of driving a liquid crystal display (LCD) device having crossing gate lines and data lines, comprising:

supplying data signals to data lines and gate signals to gate lines from the same driver;

supplying said gate signals to said gate lines such that gate signals of adjacent gate lines have opposite directions; and

supplying signal lines, each signal line commonly connected to interface pads and to input bumpers of the driver,

wherein the liquid crystal display panel is driven by a line inversion method.

8. A method of manufacturing a liquid crystal display (LCD) panel, comprising:

forming gate lines and data lines over a substrate, said gate lines and data lines crossing each other to form liquid crystal display cells;

forming pixel electrodes in region bounded by crossing data lines and gate lines,

forming a first signal line on one side of the liquid crystal display panel to be connected to an odd-numbered gate line;

forming a second signal line on the other side of the liquid crystal display panel to be connected to an even-numbered gate line; and

forming a third signal line connected to the data line,

forming a chip on film (COF) signal line, each signal line commonly connected to interface pads and to input bumpers of a driver; and

wherein the liquid crystal display is driven by a line inversion method.

9. The method of manufacturing a liquid crystal display (LCD) panel of claim 8 , wherein a resistance of the signal lines is below about 10Ω.
