A parts processing assistance system includes a three dimensional measurement unit for acquiring a three dimensional measured data about a part, a display unit for displaying the part based on the three dimensional measured data, and a virtual assembly unit for virtually assembling the part displayed by the display unit on the display unit. According to this system, assembly error can be confirmed before an actual assembly work of parts.

The present disclosure relates to a touch display panel. The touch display panel includes: a substrate including at least one first region and at least one second region which are disposed as adjacent to each other; a plurality of touch display units disposed on the substrate, wherein each of the plurality of touch display units includes: a driving element disposed in one of the at least one first region; an optical sensing member disposed in one of the at least one second region; a display device disposed on the driving element and the optical sensing member and electrically connected with the driving element; and a reflection layer disposed on the display device; wherein the optical sensing member is configured to sense light which is emitted from the display device to the reflection layer and reflected by reflection layer so as to sense a touch position.

Systems and methods are provided to enable users to interact with user terminals having a touch screen interface without requiring the user to physically contact a surface of the touch screen interface.

Provided is an infrared touch screen device including the transmission unit which contains the rectangular bezel which is constituted so that the touch screen panel is to be installed, and the multiple numbers of light transmitting elements which are installed in the lengthwise direction of corresponding bezel to one horizontal bezel and one vertical bezel respectively among the bezels and transmitting the infrared rays forward, and the reception unit which is further configured to have the multiple numbers of light receiving elements which are installed at two bezels among the bezels so that the infrared rays transmitted from the transmission unit is to be received and contain the band pass filter which makes only the infrared rays of specific wavelength band among the infrared rays transmitted from the transmission unit to be received by the multiple numbers of light receiving elements.

A liquid crystal display device includes an array substrate, a liquid crystal layer, and a color filter substrate facing the array substrate through the liquid crystal layer. The color filter substrate includes a carbon light-shielding layer, an organic pigment light-shielding layer, and color filters formed such that the organic pigment light-shielding layer overlaps with at least one of the color filters in a direction perpendicular to a substrate plane. The array substrate includes a first light sensor that detects light which passes through any of the color filters without passing through the organic pigment light-shielding layer in the direction perpendicular to the substrate plane. The array substrate further includes a second light sensor that detects light which passes through the organic pigment light-shielding layer and any of the color filters in the direction perpendicular to the substrate plane.
