Abstract
The utility model discloses a LCD screen, including polarizing plate, liquid crystal, glass substrate, diffuser plate and backlight, characterized by still includes: radio -frequency antenna, magnetic screen layer and steel backing plate, set up on the steel backing plate the magnetic screen layer, the magnetic screen sets up on the layer backlight and radio -frequency antenna, set gradually on the backlight diffuser plate and glass substrate, the last setting of glass substrate the liquid crystal, set up on the liquid crystal the polarizing plate. Through increasing the magnetic screen layer, can prevent effectively that the electromagnetic wave that the radio -frequency antenna sent from propagating to the steel backing plate direction.
Description
[technical field]
The utility model relates to a kind of LCD screen.
[background technology]
Existing card reader, majority can only be swiped the card from the back side of lcd screen, and in some cases, such operation is very inconvenient.
[summary of the invention]
In order to overcome the deficiencies in the prior art, the utility model provides a kind of LCD screen with magnetic masking layer newly.
A kind of LCD screen, comprise Polarizer, liquid crystal, glass substrate, diffuser plate and backlight, it is characterized in that, also comprise: radio-frequency antenna, magnetic masking layer and steel backing plate, described steel backing plate arranges described magnetic masking layer, described magnetic masking layer arranges described backlight and radio-frequency antenna, described backlight sets gradually described diffuser plate and glass substrate, described glass substrate arranges described liquid crystal, described liquid crystal arranges described Polarizer.
In one embodiment, described magnetic masking layer is conductor layer.
In one embodiment, described magnetic masking layer is metal level.
In one embodiment, also comprise front frame, described Polarizer, liquid crystal, glass substrate, steel backing plate and diffuser plate are positioned at described front frame, and described front frame and steel backing plate are fixed.
In one embodiment, also comprise vertical Polarizer, described Polarizer is horizontal Polarizer, and described vertical Polarizer is between described glass substrate and diffuser plate.
In one embodiment, also comprise optical filter, described optical filter is between described horizontal polaroid and glass substrate.
In one embodiment, described diffuser plate comprises the first diffuser plate and the second diffuser plate.
The beneficial effects of the utility model are: by increasing magnetic masking layer, the electromagnetic wave that can effectively prevent radio-frequency antenna from sending is propagated to steel backing plate direction.
[accompanying drawing explanation]
Fig. 1 is the structural representation of the LCD screen of a kind of embodiment of the utility model.
[embodiment]
Below the preferred embodiment of utility model is described in further detail.
As shown in Figure 1, a kind of LCD screen of embodiment, comprise Polarizer 2, liquid crystal, glass substrate 4, diffuser plate, backlight, radio-frequency antenna 10, magnetic masking layer and steel backing plate 9, described steel backing plate 9 arranges described magnetic masking layer, described magnetic masking layer is arranged described backlight and radio-frequency antenna 10, described backlight sets gradually described diffuser plate and glass substrate 4, with described liquid crystal on described glass substrate 4, described liquid crystal is arranged described Polarizer 2.
Radio-frequency antenna 10 is for sending and receiving radio frequency signal, radio-frequency antenna 10 is connected with LCD driving circuit, this LCD screen can be applied to card reader, can from the LCD screen of card reader just in the face of card carries out operation of swiping the card, such as radio frequency chip card is swiped the card operation.Described magnetic masking layer is propagated to steel plate side for stoping electromagnetic wave, prevents from causing adverse consequences.Magnetic masking layer can be conductor layer, to absorb shielding electromagnetic wave.Described magnetic masking layer can be metal level, such as layers of copper.
In one embodiment, LCD screen also comprises front frame 1, optical filter 3, vertical Polarizer 5 and glue frame 6, diffuser plate comprises the first diffuser plate 7 and the second diffuser plate 8, described Polarizer 2 is horizontal Polarizers, glue frame 6 is for fixing in former frame 1 by Polarizer 2, optical filter 3, glass substrate 4, vertical Polarizer 5, first diffuser plate 7 and the second diffuser plate 8, and steel backing plate 9 is positioned at front frame 1 and fixes with front frame 1.
Above content is in conjunction with concrete preferred implementation further detailed description of the utility model, can not assert that concrete enforcement of the present utility model is confined to these explanations.For the utility model person of an ordinary skill in the technical field; without departing from the concept of the premise utility; some simple deduction or replace can also be made, all should be considered as belonging to the scope of patent protection that the utility model is determined by submitted to claims.
