Abstract
The invention relates to a backlight screen having six light-emitting diode (LED) lamps. The backlight screen comprises a light guide plate, a backlight flexible printed circuit (FPC) soft plate and a lower diffusion film. The backlight screen is characterized in that: the six LED lamps are uniformly distributed between the lower diffusion film and the light guide plate; and the LED lamps are connected to a main board and a touch screen of the backlight screen by the backlight FPC soft plate. Compared with the conventional backlight screen having four LED lamps, the backlight screen having the six LED lamps has the advantages that: brightness is improved by 40 to 60 percent; and the six LED lamps are matched with a power supply of the main board, and a screen interface is matched with a main board interface.
Description
Technical field
The present invention relates to the backlight screen of a kind of LED of employing lamp, further relate to a kind of backlight screen of 6 LED lamp light sources as light source.
Background technology
In recent years, the backlight development is very fast, constantly there are new technology, new product to release, LED-backlit progressively enters industrialization, certain scale has been arranged, compared CCFL, LED has tangible power savings advantages, it mainly can be applicable to computer monitor, mobile telephone display or the like, but still there are many improvements that need in LED-backlit.
Now, show that the backlight device in the module is to improve the surface brightness that shows module from use 4 LEDs to be improved to using the effect of 6 LEDs illumination, make so-called " high bright screen ", the module surface brightness that 6 LEDs throw light on than 4 LEDs can improve the brightness about 40%～60%, the general screen surfaces brightness of using 4 LEDs to be called general bright screen has only 180～200cd/mm (square millimeter), and can reach 300～320cd/mm (square millimeter) with the screen surfaces brightness that 6 LEDs are called high bright screen;
Yet, increasing the problem that can bring mobile telephone power consumption to rise behind 2 LEDs in addition, the power consumption of 4 LEDs is 3.2v*60mA; The power consumption of 6 LEDs is 3.2v*90mA, and this all needs the power supply support on the mainboard, also needs in addition to shield interface and mainboard interface and has all reserved the interface of 6LED and mate.
Summary of the invention
In view of above content, be necessary to provide a kind of and can mate, shield the backlight screen that interface and mainboard interface and 6LED lamp all mate with motherboard power supply.
The invention provides a kind of backlight screen with 6 LED lamp, comprise light guide plate, FPC soft board backlight, following diffusion barrier, wherein at following evenly distributed 6 LED between diffusion barrier and the light guide plate, described LED is connected on the mainboard and touch-screen of backlight screen by FPC soft board backlight.
By the interface of reserving, touch-screen and mainboard and LED lamp mate, thereby make the better highlighted function of performance of LED lamp.
Preferably, described backlight screen is the mobile phone touch-screen.
Compared with prior art, the invention has the advantages that:
1, provides 6LED, improved illuminating effect, increased the brightness of backlight screen;
2, motherboard power supply provides sufficient power supply for 6 LED lamp, and LED etc. can steady operation.
3, the raising of the backlight screen of 6 LEDs than 4 brightness of 40%-60%.
Description of drawings
The invention will be further described in conjunction with the embodiments with reference to the accompanying drawings.
Fig. 1 is that the present invention has the three-view diagram that 6 LED lamp get the backlight screen module.
Fig. 2 is that the present invention has the blast sketch that 6 LED lamp get the backlight screen modular structure.
Reference numeral is represented respectively among Fig. 2: (1) glue frame backlight, (2) light guide plate, (3) reflectance coating, (4) following diffusion barrier, (5) down bright enhancement film (6) go up bright enhancement film (7) black and white double faced adhesive tape (8) FPC soft board backlight (9) FPC double faced adhesive tape (10) LED (11) chase (12) down polaroid (13) TFT LCD (14) go up polaroid (15) main FPC (connection mainboard) (16) IC (17) TP resistive touch screen
Embodiment
See also Fig. 1 and Fig. 2, a kind of backlight screen of preferred embodiment of the present invention with 6 LED lamp, comprise light guide plate, FPC soft board backlight, following diffusion barrier, wherein at following evenly distributed 6 LED between diffusion barrier and the light guide plate, described LED is connected on the mainboard and touch-screen of backlight screen by FPC soft board backlight.
Preferably, described backlight screen is the mobile phone touch-screen.
In addition, described backlight screen is the mobile phone touch-screen.
The backlight screen module in use must be after the stable access of positive supply, ability output signal level or disconnection back incoming signal level; During use, the order that inserts logic power and driving power is first logic power rear drive power supply.
The present invention is primarily aimed at the improvement that the LED-backlit screen is carried out, the above only is preferred embodiment of the present invention, non-so promptly limit to claim of the present invention, so the simple and easy variation and the equivalent transformation of doing with instructions of the present invention and graphic content such as all should be contained in the claim of the present invention.
Claims (2)
1. the backlight screen with 6 LED lamp comprises light guide plate, FPC soft board backlight, following diffusion barrier, it is characterized in that:
At following evenly distributed 6 LED between diffusion barrier and the light guide plate, described LED is connected on the mainboard and touch-screen of backlight screen by FPC soft board backlight.
2. the described backlight screen of claim 1, wherein said backlight screen is the mobile phone touch-screen.
