AI Technical Summary

Benefits of technology

This technology allows for multiple points or fingers on an object being scanned without affecting its electrical properties like voltage potentials. It also has improved sensitivity when capturing images with this technique compared to traditional methods that only capture one point at once.

Problems solved by technology

Technological Problem: Current Liquid Crystals Displays (LCD) technology has limitations such as requiring multiple steps when users click on buttons due to their lack of intuitiveness compared to traditional CRT displays. Additionally, existing Touch Panel Technology does not allow for accurate detection over environmental factors like light levels which may impact how well they work.

Embodiment Construction

[0037] The invention provides a display device. The display device mentioned here includes but is not limited to a flat display device using a display panel. The display panel preferably includes a liquid crystal display panel, an organic light emitting diode display panel or other display panels. In addition, the liquid crystal display panel includes a transmissive liquid crystal display panel, a reflective liquid crystal display panel, a transflective liquid crystal display panel and other types of liquid crystal display panels.

[0038] As shown in FIG. 2 , the display device of the present invention includes a base 100 , a display panel 300 , a sensor panel 500 and a light source 700 . The display panel 300 is disposed on the base 100 . In this embodiment, the display panel 300 is preferably a liquid crystal display panel; however, in different embodiments, the display panel 300 can also be an OLED panel or other display panels 300 . In addition, when the display panel 300

Abstract

This invention provides a kind of display device with a touch input function; the display device includes the dock, display panel, sensor plate and the light source. Display panel is installed on the dock.The display panel has a driving circuit layer including plural light sensor components. Sensor plate with interface and underside is installed at the side of the display panel, thereinto the underside looking towards the display surface of display panel. Light source is installed along the edge of the sensor plate, and launch into the sensor plate. When the contact surface in the state of no touching interface, the light in contact with a total reflection on interface and underside; when a specific location of the contact surface in the state of contact interface, the specific location of contact surface will scatter parts of light penetrating underside to arrive components. This invention can be carried out more input and fingerprint recognition, without the impact from the environment of electric field, improves the accuracy of sensors.
