Summary of the invention
The purpose of this utility model is to solve the deficiencies in the prior art, but the LCDs that provides a kind of subregion to show, this display screen can be selected viewing area in use, can effectively save electric energy, and service time is longer.
For achieving the above object, the technical solution adopted in the utility model is:
But the LCDs that a kind of subregion shows, comprise display screen and zoning controller, the upper end of display screen or lower end are connected with the line frequency controller, the left end of display screen or right-hand member are connected with row controller frequently, the rear of described display screen is provided with backlight module, described backlight module comprises light guide plate, LED lamp and light emission controller, and described LED lamp is distributed in the surrounding of light guide plate, and the LED lamp is connected with light emission controller; Line frequency controller, row controller, light emission controller frequently all are connected with the zoning controller signal.
Further, described display screen is connected with touch-screen, and touch-screen is connected with the zoning controller signal.
Further, described backlight module also comprises circuit board, and described LED lamp is fixed in circuit board, and the surface of described circuit board is provided with reflector layer.
Further, the side of described light guide plate is provided be used to holding the accommodation hole of LED lamp, and described LED lamp is arranged in accommodation hole.
Further, described accommodation hole semicircular in shape.
Further, described circuit board is aluminium base.
The beneficial effect that the utility model is obtained is: the utility model adopts line frequency controller, row controller and zoning controller frequently, makes LCDs can carry out the small screen demonstration, saves electric energy, extends working time.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the schematic diagram that subregion of the present utility model shows.
Fig. 3 is the structural representation of backlight module of the present utility model.
Reference numeral is:
1---display screen 2---line frequency controller
3---row are controller 4 frequently---light guide plate
5---circuit board 6---LED lamp
7---accommodation hole 8---backlight module
9---zoning controller.
Embodiment
Below in conjunction with Fig. 1 to Fig. 3, and embodiment is described further the utility model.
Embodiment: referring to Fig. 1 to Fig. 3.
But the LCDs that a kind of subregion shows, comprise display screen 1 and zoning controller 9, the upper end of display screen 1 or lower end are connected with line frequency controller 2, the left end of display screen 1 or right-hand member are connected with row controller 3 frequently, the rear of described display screen 1 is provided with backlight module 8, described backlight module 8 comprises light guide plate 4, LED lamp 6 and light emission controller, and described LED lamp 6 is distributed in the surrounding of light guide plate 4, and LED lamp 6 is connected with light emission controller; Line frequency controller 2, row controller 3, light emission controller frequently all are connected with zoning controller 9 signals.
In use, the line frequency controller 2 of display screen 1 and row are controller 3 receiving video signals frequently for the utility model, and show on display screen 1, and backlight module 8 is luminous simultaneously illuminates demonstration, so that the people soon.Due to the mobile phone of current giant-screen, the very power consumption of use of palm PC.In use, can select the small screen district, giant-screen district to show according to the content shown, as seeing note, while seeing the data of character property, can select the small screen to carry out, by zoning controller 9, be controlled in the small screen district and show and luminous, carrying out that the small screen shows and when luminous, zoning controller 9 will be controlled the signal transfer region territory of line frequency controller 2 and row frequency controller 3, and control LED lamp 6 luminous position and number, make the viewing area of territory, cue field and backlight module 8 overlapping; Thereby reach the effect of saving electric energy; Simultaneously, also can when electric energy is less, select the small screen district to show, save electric energy, extend working time.
In addition, present mobile phone, computer are all very powerful, after realizing that subregion shows, can show different contents in the zones of different of display screen 1, improve service efficiency.As mobile phone when seeing a film, receive note suddenly, just can to zoning controller 9, operate by input block, make LCDs carry out subregion, a part still shows film, a part is used for showing note, after the user finishes watching note, can also the Zai Gai district carry out editing short message and reply, after having operated, can close the short message in this district, by zoning controller 9, screen is reduced to giant-screen and show film.During computation, also can be used for showing film in subregion, a part is for showing game, and game, film are neglected neither.If the profile is enough certainly, all right browsing page, accomplish wholeheartedly multiplex.
Further, described display screen 1 is connected with touch-screen (not shown in FIG.), and described touch-screen is fixed in the front of display screen 1, and touch-screen is connected with zoning controller 9 signals.
