Embodiment Construction

[0019] Specific embodiments of the invention will now be described in detail with reference to examples and accompanying drawings.

[0020] The liquid crystal display device with a touch screen according to the present invention includes a panel driving circuit and a liquid crystal module. The panel drive circuit includes a gate drive block, a data drive block, and a signal control block. Since the gate driving block and the signal control block have the same structure as those of the related art, except for the data driving block, detailed description thereof will be omitted.

[0021] figure 2 It is a circuit diagram illustrating the structure of the liquid crystal module of the touch screen liquid crystal display device according to the present invention.

[0022] Such as figure 2 As shown, the liquid crystal module 200 of the capacitive touch screen liquid crystal display device according to the present invention includes a plurality of gate lines G formed on the subst...

Abstract

An touch screen liquid crystal display device includes a panel driving circuit including a gate driving block, a data driving block, and a signal control block and a liquid crystal module that stores data in data pixels through a data pixel line, to which the data pixels are connected, in response to a data signal applied from the data driving block, and reads data through a read pixel line to which read pixels are connected. The read pixels are connected to the data pixels through a share line.

Description

technical field [0001] The present invention relates to a touch screen liquid crystal display device, in particular to a touch screen liquid crystal display device that stores data in pixels and reads touch information by using a liquid crystal module having a structure of sharing data pixel lines and reading pixel lines. Background technique [0002] With the recent development and popularization of Graphical User Interface (hereinafter referred to as "GUI") systems, touch screen liquid crystal display devices having a simple input interface have been widely used. The touch screen liquid crystal display device is an input device replacing a keyboard and a mouse. If a user directly touches a touch panel mounted on a liquid crystal display panel with a finger, desired operations can be performed. [0003] The touch screen liquid crystal display device allows users to complete business operations in a GUI environment such as a Windows operating system, and can be widely used i...
