Problems solved by technology

However, the touch screen panel also brings some problems: increasing the manufacturing cost of this LCD, reducing the product yield due to the additional process of adhering the touch screen panel on the liquid crystal panel, reducing the brightness of the liquid crystal panel, and Increased overall product thickness
[0007] However, the output characteristics of the photosensor vary depending on external environments such as the intensity of external light, the intensity of backlight, and temperature, so that many errors may occur during light sensing.

Embodiment Construction

[0038]The invention will be described in more detail below with reference to the accompanying drawings, in which preferred embodiments of the invention are shown. However, the present invention can also be embodied in various different forms, and the present invention should not be limited to the various embodiments set forth herein. Rather, these embodiments are provided only to fully disclose the present invention and to more fully explain the scope of the present invention to those skilled in the art.

[0039] In the drawings, the thickness of layers, films, panels, regions, etc., are exaggerated for clarity. Throughout the specification, the same reference numerals denote the same elements. It will be understood that when an element such as a layer, film, region, or substrate is referred to as being on another element, it can be directly on the other element or intervening elements may also be present. In contrast, when an element is referred to as being directly on anot...

Abstract

The present invention relates to a liquid crystal display (LCD) that includes a liquid crystal panel assembly including sensing data lines, variable capacitors having a capacitance changed by pressure and connected to the sensing data lines, and reference capacitors connected to the sensing data lines, and a plurality of sensing signal output parts formed separately from the liquid crystal panel assembly and respectively connected to the sensing data lines to generate an output signal based on a sensing data signal flowing through the sensing data lines. Each of the sensing signal output parts includes an output transistor connected to each of the sensing data lines, while the output transistor includes a metal oxide semiconductor (MOS) transistor that has better performance, smaller size, and lower power consumption than a thin film transistor (TFT).

Description

[0001] This application claims priority from Korean Patent Application No. 10-2006-0008850 filed on Jan. 27, 2006, the contents of which are incorporated herein by reference in their entirety. technical field [0002] The present invention relates to a display device, a liquid crystal display (LCD) and a method thereof. More particularly, the present invention relates to a display device and LCD for determining screen touches and touch locations, and methods thereof. Background technique [0003] A liquid crystal display (LCD), as a typical display device, includes two display panels having pixel electrodes and a common electrode, and a liquid crystal layer with dielectric anisotropy arranged between the two display panels. The pixel electrodes are arranged in a matrix form and connected to switching elements including thin film transistors (TFTs), and data voltages are sequentially applied to the switching elements. The common electrode is formed on the entire surface of t...
