Problems solved by technology

[0002] At present, there are many kinds of touch screens, including resistive screens or capacitive screens, but for existing ordinary display screens or similar devices, the touch function cannot be realized, and there is no relevant technical report, which limits the use of ordinary display screens or similar devices. touch operation
[0003] Touch operation is a convenient operation. If users with ordinary display screens need touch operation, they must replace the display screen. The display screen is a hardware with a very low replacement frequency. Users only need to replace the display screen due to touch operation. increased costs

Embodiment Construction

[0037] The present invention will be further described below in combination with specific embodiments and accompanying drawings.

[0038] Touch-operated controls include

[0039] A ranging sensor to measure the distance from the touch point to a fixed origin;

[0040] An angle sensor for measuring the angle between the touch point and a reference line passing through a fixed origin;

[0041] The contacts are respectively connected with the distance measuring sensor and the angle sensor;

[0042] The control chip receives the signals from the ranging sensor and the angle sensor, and outputs the coordinate signal of the touch point relative to the fixed origin.

[0043] Such as figure 1 As shown, the contact 3 includes a "T"-shaped body, a ball 9 is embedded in the front end of the vertical part of the body, a spring 8 is arranged behind the ball, and the second contact 7 at one end of the control switch is mechanically connected to the spring 8 , when the spring 8 is compre...

Abstract

The invention discloses a touch operation control device, a display screen realizing touch function and method thereof, relates to a product which can realize touch function for common display screens or similar devices and a method thereof, aiming at realizing the purpose that common display screen can have touch function. The device comprises a ranging sensor, an angular transducer, a contact terminal and a control chip; wherein, the ranging sensor is used to measure the distance of a touch point to a fixed origin point, the angular transducer is used to measure the included angle between the touch point and a reference linear which passes the fixed origin point, the contact terminal is connected with the ranging sensor and the angular transducer respectively, and the control chip is used to receive the signals from the ranging sensor and the angular transducer and output the signalcoordinates of the touch point relative to the fixed origin point; the contact terminal contains a body in the shape of T, the front end of the vertical part thereof is a ball bearing, a spring is mounted behind the ball bearing; when the spring is compressed, the end of a control switch can be communicated with the other end of the control switch; the vertical part thereof is sheathed with a joining link in a loose fit way, and the joining link is connected with the ranging sensor and the angular transducer.

Description

technical field [0001] The invention relates to IT products, in particular to a product and method capable of enabling common display screens or similar devices to realize touch functions. Background technique [0002] At present, there are many kinds of touch screens, including resistive screens or capacitive screens, but for existing ordinary display screens or similar devices, the touch function cannot be realized, and there is no relevant technical report, which limits the use of ordinary display screens or similar devices. touch operation. [0003] Touch operation is a convenient operation. If users with ordinary display screens need touch operations, they must replace the display screen. The display screen is a hardware with a very low replacement frequency. Users only need to replace the display screen due to touch operation. Increased costs. Contents of the invention [0004] The purpose of the present invention is to provide a device that can make a common displ...
