Abstract

The invention relates to a projection system with a touch control function. The projection system comprises a projector, a light-emitting module and an adjusting mechanism. The projector and a display plane are oppositely arranged. The light-emitting module is arranged between the projector and the display plane and close to the display plane, and is used for sending light rays to form a light curtain. The adjusting mechanism is arranged on the light-emitting module for turning the light-emitting module to adjust an angle of the light curtain and the display plane. Since the projection system with the touch control function is provided with the adjusting mechanism capable of turning the light-emitting module, when the light curtain inclines relative to the display plane, any user can easily operate the adjusting mechanism to turn the light-emitting module for adjusting the angle of the light curtain and the display plane. The projection system with the touch control function is convenient to operate, special calibrating instruments are not needed, and adjusting time can be effectively saved.

Description

technical field [0001] The present invention relates to a projection system, in particular to a projection system with a touch function. Background technique [0002] With the maturity of the touch system, electronic devices with large size and multi-touch technology will become the mainstream in the future. At present, compared with other methods, such as resistive, capacitive, ultrasonic, etc., the optical touch system has the advantages of lower cost and easier implementation. With the advancement and development of science and technology, projection systems with touch functions are becoming more and more popular. Generally speaking, a projection system with a touch function uses a light curtain formed by a laser as a touch sensing light source. In order for the lens of the projector to accurately sense any touch point on the display plane, the light curtain needs to maintain a certain parallelism with the display plane. When the light curtain is skewed relative to the...
