Abstract

A touch display panel assembly is provided. The touch display panel assembly includes a display panel having a display surface on a side of the display panel for emitting light, a touch light detectorat a periphery of the display panel for detecting the emitted light and having an iris that faces in a direction substantially normal to the display surface for passing the emitted light into the touch light detector, and a light guide above the iris for guiding the emitted light from the display surface to the iris and into the touch light detector. The touch display panel assembly has an improved viewing angle and can be made thinner as compared to conventional touch display panels due to the improved features of the touch light detector.

Description

technical field [0001] The present application relates to touch display panels, and more particularly, to touch display panels having improved photodetectors that recognize touch activity by detecting changes in light. Background technique [0002] The touch panel may be an infrared type, a resistive film type, an electrostatic capacity type, an ultrasonic type, or a pressure sensor type touch panel. An optical type touch panel such as an infrared type touch panel can be used for a large screen such as a plasma display panel. [0003] Existing touch display panels have a touch photodetector comprising two mirrors, which respectively extend along mutually orthogonal edges of the flat display panel. The reflector has a reflective plane facing the display unit side of the flat display panel and is attached at an angle of 45 degrees relative to the inside of the display panel. The touch photodetector also includes two photoreceivers facing the two mirrors on opposite edges fac...
