Claim One:
1. A display device having a multi-touch recognition function, comprising: a display panel for displaying display data representative of a display image; a plurality of cameras disposed at an edge of the display panel; a processor that detects a touch area using at least first and second images captured by two cameras of the plurality of cameras, respectively, the touch area being located on a touchable side of the display panel; a controller synchronized with the processor to control the displaying of a background image on the display panel and the capture of the first and second images by the processor, at least one non-reflective member in such a spatial relationship with a corresponding each of the plurality of cameras as to prevent an optical interference from an incident light; and a bracket for receiving the display panel, the plurality of cameras and the at least one non-reflective member, wherein a first camera of two cameras captures the first image of the display panel and a second camera of two cameras captures the second image of the display panel, respectively, and the processor compares each of the first and second captured images with a displayed image to detect the touch area, and wherein the controller synchronizes the first and second cameras to capture the first and second images substantially simultaneously, wherein the at least one non-reflective member includes one of a black layer, an anti-reflector, and first and second polarizing filters which are deposited, the optical absorption axes of which cross each other, and wherein the at least one non-reflective member is substantially in front of the corresponding each of the plurality of cameras and is lifted upward as much as a designated height from a surface of the display panel, and wherein the bracket has protrusions at an inner side facing the edges of the display panel, and wherein the plurality of cameras are disposed on the protrusions and the at least one non-reflective member is overlapped with the edge of the display panel, wherein the protrusions are parallel to the display panel, and wherein a bending portion of the bracket covers a top of the at least one non-reflective member.
