Abstract

Provided display panel includes a lower substrate, an upper substrate and a liquid crystal layer interposed therebetween. The lower substrate is divided into a display region for displaying an image and an adjacent peripheral region, and includes a plurality of pixel parts, a plurality of photo sensing parts, and a reflection preventing layer. The pixel parts are disposed in the display region for forming an image. The photo sensing parts are disposed in the display region for detecting the location of an object placed on or immediately adjacent to a surface of the display panel. The upper substrate faces the lower substrate, and includes a black matrix corresponding to the peripheral region. The reflection preventing layer is disposed in the peripheral region to prevent the black matrix from reflecting light back onto the photo sensing parts and thereby adversely affecting their operation.

Description

technical field [0001] The present invention relates generally to a display panel, and more particularly to a liquid crystal display (LCD) panel having an integrated touch screen with an image sensor and a display incorporating the same. Background technique [0002] Typically, a conventional touch screen panel is an input device disposed on a display panel such that data can be input to a system including the panel using objects such as fingers, stylus, pens, and the like. A typical touch screen panel includes opposing first and second substrates on which first and second transparent electrodes are disposed, respectively. [0003] If such conventional touch screen panels are only attached to the outer surface of the display panel, they may adversely affect the optical properties of the panel and undesirably increase its thickness. To avoid these problems, touch screens are often integrated internally into the display panel. [0004] Display panels often include an image s...
