Abstract
The invention discloses a remote control touch screen and a laser touch pen thereof, which are applied to the fields of computers, televisions, and the like. By using a matrix and a laser beam which are formed on the basis of a photoelectric switch, the prior touch screen is expanded and can be used through remote control compared with the prior touch screen which can only be used within a short distance.
Description
Technical field
The present invention relates to a kind of touch-screen, relate in particular to a kind of based on photoelectric remote control touch screen and laser felt pen thereof.
Background technology
Computer, PDA, mobile phone all have the product of band touch-screen now, but these products are all restricted, and their felt pen or finger must the in-plant touch-screens that touches.Present touch-screen has resistive touch screen, capacitive touch screen, infrared-type touch-screen, surface acoustic wave touch screen etc.
Use the user of projector all to like to use a kind of projection pen now, this pen sends a branch of red laser, and impinging upon has a luminous point on the projection screen.
Summary of the invention
The purpose of this invention is to provide a kind of can the screen and the laser felt pen based on photoelectric remote control touch.
The all similar projection pen of the appearance of laser felt pen and principle, (red or its allochromatic colour) can give off laser beam.A button is arranged above, can control moment and launch/stop emission of lasering beam.
In display screen surface two groups of parallel wire groups are arranged, two groups of leads are orthogonal, one group of level, and one group is vertical, place a photoelectricity node at per two lead infalls, each photoelectricity node is made up of two reflective electric switches, and each switch connects a lead, and the two ends of every lead are connected on the curtage detection table, separated time according to lead, the detection table also is divided into horizontal detection table group and vertical detection table group, and the result of two groups of detection tables send microprocessor, with the connectivity of monitoring lead.See Fig. 1.
Beat on remote control touch screen when the laser beam of laser felt pen, disconnected by two reflective electric switches in the photoelectricity node of light, measure the break-make of lead in the matrix, just can know the x of luminous point, the y coordinate.
Optoelectronic switch in this product will use not too responsive, so that reduce the influence of daylight, light to greatest extent.
The invention has the beneficial effects as follows and outside certain distance, to use laser felt pen operating and remote controlling touch-screen.
Description of drawings
Fig. 1 is the matrix structure synoptic diagram that the photoelectricity node is formed.
Embodiment
Embodiment
The large scale liquid crystal TV is made the remote control touch screen, the infrared ray control function of switch TV is incorporated into the laser felt pen, add soft keyboard input method and handwritten word identification software in the TV set-top box, we just can write article on the large screen television in the parlor, send out mail, online chat.
Claims (2)
1. a remote control touch shields and the laser felt pen, it is characterized in that: two groups of parallel wire groups are arranged in display screen surface, two groups of leads are orthogonal, one group of level, one group vertical, place a photoelectricity node at per two lead infalls, each photoelectricity node is made up of two reflective electric switches, each switch connects a lead, the two ends of every lead are connected on the curtage detection table, and according to the separated time of lead, the detection table also is divided into horizontal detection table group and vertical detection table group, the result of two groups of detection tables send microprocessor, with the connectivity of monitoring lead.
2. a kind of remote control touch screen according to claim 1 and laser felt pen thereof is characterized in that it has a felt pen that can send and stop to give off laser beam.
