Problems solved by technology

[0003] However, the developed touch screen is generally a rectangular touch screen installed on the front of the driver's side, so the space inside the vehicle is not effectively used, the design of the display device may be difficult to match the curved design of the vehicle, and the design cost of adjusting the display module to a curved surface May increase, it may be difficult to recognize touches from general objects such as gloves or pens, and touch errors may occur due to the form of the flat touch screen

Abstract

The invention discloses a display device used for identifying touch, and the display device is used for identifying the touch on displays which are matched with the internal design of a vehicle and have different shapes. The display device used for identifying the touch comprises a screen, a visible light generator, an infrared light generator, a projector and an optical sensor, wherein the visible light generator is controlled by a processor and is configured to project a preset image onto a screen via by visible light; the infrared light generator is configured to generate scattered light by an infrared light source according to user touch; the projector is configured to project visible light from the visible light generator and the infrared light source from the infrared light generator onto the screen; the optical sensor is configured to detect the scattered light; and all the components are controlled by the processor.

Description

technical field [0001] The present invention relates to a display device configured to recognize a touch, and more particularly, to a display device configured to recognize a touch on a display having a different shape to match the interior design of a vehicle, whereby the The constituent elements configure the display device to reduce manufacturing cost. Background technique [0002] Recently, in response to enhancements in vehicle functions, various input devices capable of inputting commands with respect to various vehicle functions have been developed, such as key panel input devices, jog dials, touch screens, and the like. In recent years, touch screens have been actively used in audio video navigation (AVN) instrument clusters. [0003] However, the developed touch screen is generally a rectangular touch screen installed on the front of the driver's side, so the space inside the vehicle is not effectively used, the design of the display device may be difficult to matc...
