Abstract
A hidden infrared remote controlling receiving device used for liquid crystal display screen comprises a liquid crystal display screen and a metallic plate which is installed on the back side of the liquid crystal display screen, wherein a circular hole is opened on the metallic plate, an infrared receiver which is connected with a current board tightly clings to the back of the circular hole, and the circular hole on the metallic plate also can cling to a lens and then clings to the infrared receiver which is connected with the current board, wherein the lens can in a rotary-table shape of big front end and small rear end, and the front end big surface clings to the circular hole of the metallic plate, the rear end small surface clings to the infrared receiver. The hidden infrared remote controlling receiving device opens a circular hole on the metallic plate on the back side of the liquid crystal display screen, which enables infrared signals which are emitted by the remote controller to directly pass through the liquid crystal display screen and to be received through the lens, thereby, the remote controlling receiving window is hidden, which enables the equipment has more beautiful appearance, more convenient manufacture and can be widely used on the liquid crystal display screens of the equipments which needs infrared control.
Description
Technical field
The utility model relates to a kind of infrared remote control receiving trap, particularly a kind of hidden infrared remote control receiving trap that is used for LCDs.
Background technology
LCDs has radiationless, and volume is thin in light weight, the power consumptive province, and plurality of advantages such as appearance looks elegant have progressively substituted traditional kinescope, are widely used in televisor, projector, apparatus such as computer.Conventional LCDs mainly is made up of liquid-crystalline glasses module and backlight source module two parts, it roughly which floor structures such as polaroid, ito glass, liquid crystal matter, light guide plate, reflecting plate, diffuser plate, the plate that adds lustre to, optical filters is made of, and they all have certain light transmission.In order to protect module, around whole LCDs, reach the back side and all use metal edge frame and metal base plate to be wrapped up and liner, influence its inherent quality and serviceable life in case be subjected to external force collision.For easy to use, people often need to control with infrared remote control its use.But because infrared ray can not pass opaque object, so generally be to offer a transparent wicket in the front of equipment such as LCD TV, liquid crystal projection apparatus, behind wicket, place infrared remote receiver, perhaps LCDs is walked around in the infrared remote receiver position, keep dislocation with LCDs, so that seeing through LCDs, the infrared emission signal is received by the receiver, the lead-in wire of receiver like this certainly will extend, even receiver is exposed to device external, influenced the outward appearance of equipment to a certain extent, also brought inconvenience to installation.
Summary of the invention
The purpose of this utility model is at the defective of above-mentioned prior art and deficiency, design a kind of infrared remote control receiving trap of hidden for liquid crystal display equipment, do not need on device panel, receive window to be set and influence product appearance to reach, can make LCDs can have the distant control function of normal display effect again simultaneously.
The technical scheme that its technical matters that solves the utility model adopts is: this is used for the hidden infrared remote control receiving trap of LCDs, the sheet metal that it comprises LCDs and is installed on the LCDs back side, on sheet metal, offer circular hole, be close to the infrared remote receiver that joins with circuit board behind the circular hole.
Circular hole on the described sheet metal also can be by being close to lens, and then scioptics paste mutually with the infrared remote receiver that circuit board joins.
Described lens are pre-large post-small truncated cone-shaped, and big of the front end of truncated cone-shaped lens pastes mutually with the sheet metal circular hole, and the rear end facet is close to infrared remote receiver.
The utility model is provided with circular hole on the sheet metal at the LCDs back side, the infrared signal that telepilot is launched can directly pass LCDs and be received by infrared remote receiver, hidden remote control receive window, make equipment appearance more attractive in appearance, processing more convenient, needing on the liquid crystal display equipment of infrared remote control can be widely used in.
Description of drawings
Fig. 1 is the utility model structural representation.
Fig. 2 is that the utility model installs perspective exploded view behind the lens additional.
Label among the figure is: 1-LCDs, 2-lens, 3-infrared remote receiver, 4-circuit board, 5-sheet metal, 6-circular hole.
Embodiment
Shown in Figure 1, this hidden infrared remote control receiving trap that is used for LCDs comprises LCDs 1, around the LCDs and the back side is by metal edge frame and sheet metal 5 parcel and liners, have circular hole 6 on the sheet metal 5, be close to the infrared remote receiver 3 that joins with circuit board behind the circular hole on the sheet metal.
Shown in Figure 2, in order to strengthen the signal of infrared, be preferably on the circular hole 6 of sheet metal and be close to lens 2, be close to the infrared remote receiver 3 that joins with circuit board at lens 2 rear end faces then.In order to remedy the signal attenuation that the infrared penetration LCDs is caused, the truncated cone-shaped big before these lens preferably are, that the back is little, the large end face of truncated cone-shaped lens is close to the circular hole on the sheet metal 5, and small end face is close to infrared remote receiver 3.Described infrared remote receiver links to each other with circuit board 4 by lead.
When pressing Infrared remote controller, infrared signal penetrates LCDs, and the circular hole by on the LCDs back metal plate is directly received by infrared remote receiver.If install lens additional between the circular hole of sheet metal and infrared remote receiver, the circular hole scioptics on the infrared signal penetrating metal plate are received by infrared remote receiver.Perhaps on the infrared signal penetrating metal plate behind the circular hole,, make that the signal intensity on the infrared remote receiver face is multiplied through converging of truncated cone-shaped lens.In general, big end of truncated cone-shaped lens diameter is big more, and the infrared ray that can converge is just many more, and the infrared signal that receives is also just strong more, and remote control distance is just far away more.Transmitting and receiving of infrared remote control is ripe technology.The utility model adopts conventional infrared remote control transmission technology, adopts coded format to send, and carries out dependent instruction again after the receiving end decoding of receiver, to avoid the infrared interference between distinct device, improves the accuracy of infrared remote control identification.
Claims (3)
1, a kind of hidden infrared remote control receiving trap that is used for LCDs, the sheet metal that it comprises LCDs and is installed on the LCDs back side, it is characterized in that offering on the sheet metal circular hole, the rear end face of circular hole is close to the infrared remote receiver that joins with circuit board.
2, the hidden infrared remote control receiving trap that is used for LCDs according to claim 1 is characterized in that being close to lens behind the circular hole on the described sheet metal, and the rear end face of lens is close to the infrared remote receiver that joins with circuit board.
3, the hidden infrared remote control receiving trap that is used for LCDs according to claim 2, it is characterized in that described lens are pre-large post-small truncated cone-shaped, big of the front end of truncated cone-shaped lens pastes mutually with the sheet metal circular hole, and the rear end facet is close to infrared remote receiver.
