Abstract

Provided is a timing adjusting method for a touch screen liquid crystal display device. A liquid crystal module of the touch screen liquid crystal display device has a structure in which a data line connected to data pixels and a read line connected to read pixels are shared by a share line, and a display mode section for displaying data of the data pixels is performed separately from a read mode section for reading data of the read pixels.

Claims

1. A timing adjusting method for a touch screen liquid crystal display device, comprising:

a liquid crystal module of the touch screen liquid crystal display device has a structure in which a data line connected to data pixels and a read line connected to read pixels are shared by a share line, and

a display mode section for displaying data of the data pixels is performed separately from a read mode section for reading data of the read pixels.

2. The timing adjusting method for the touch screen liquid crystal display device according to claim 1, wherein the read mode section includes:

a share line initialization duration for initializing the share line to a reference voltage after the display mode section is ended;

a read-out duration for storing and processing the data of the read pixels; and

a share line and data line initialization duration for initializing the share line and the data line to a predetermined operating voltage before a subsequent display mode section is started.

3. The timing adjusting method for the touch screen liquid crystal display device according to claim 2, wherein the read-out duration includes:

a read data storage interval for storing the data of the read pixels; and

a read data conversion interval for converting the stored data of the read pixels into a digital signal.

4. The timing adjusting method for the touch screen liquid crystal display device according to claim 2, wherein, in the share line and data line initialization duration, the share line and the data line are initialized to the operating voltage and simultaneously the digital signal is transmitted to a timing controller.

5. The timing adjusting method for the touch screen liquid crystal display device according to one of claims 2, wherein the operating voltage has a value corresponding to a half of a maximum operating voltage of the touch screen liquid crystal display device.

6. The timing adjusting method for the touch screen liquid crystal display device according to one of claims 3, wherein the operating voltage has a value corresponding to a half of a maximum operating voltage of the touch screen liquid crystal display device.

7. The timing adjusting method for the touch screen liquid crystal display device according to one of claims 4, wherein the operating voltage has a value corresponding to a half of a maximum operating voltage of the touch screen liquid crystal display device.
