Abstract

The utility model relates to a backlight screen with six light-emitting diode (LED) lamps, which comprises a light guide panel, a backlight flexible printed circuit (FPC) board and a lower diffusion barrier. The backlight screen is characterized in that six LEDs are distributed evenly between the lower diffusion barrier and the light guide panel, and the LEDs are connected onto a main panel and a touch screen of the backlight screen through the backlight FPC board. Brightness of the backlight screen is improved by 40% to 60% compared with the original backlight screen with 4 LEDs, the six LEDs are matched with a main panel power supply, and a screen interface is matched with a main panel interface.

Description

Backlight screen with 6 LED lamp

Technical field

The utility model relates to the backlight screen of a kind of LED of employing lamp as light source, further relates to a kind of backlight screen of 6 LED lamp light sources.

Background technology

In recent years, the backlight development is very fast, constantly has new technology, new product to release; LED-backlit progressively gets into 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 "; 6 LEDs can improve the brightness about 40%～60% than the module surface brightness of 4 LEDs illuminations, and the screen surfaces brightness of generally 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 need shield in addition interface and mainboard interface and all reserve 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 utility model provides a kind of backlight screen with 6 LED lamp; Comprise LGP, FPC soft board backlight, following diffusion barrier; Wherein at following evenly distributed 6 LED between diffusion barrier and the LGP, said LED is connected on the mainboard and touch-screen of backlight screen through FPC soft board backlight.

Through the interface of reserving, touch-screen and mainboard and LED lamp mate, thereby make the LED lamp better bring into play high bright function.

Preferably, said backlight screen is the mobile phone touch-screen.

Compared with prior art, the advantage of the utility model is:

1,6LED is provided, has improved illuminating effect, increased the brightness of backlight screen;

2, motherboard power supply is that 6 LED lamp provide sufficient power supply, and LED etc. can steady operation.

3, the raising of the backlight screen of 6 LEDs than 4 brightness of 40%-60%.

Embodiment

See also Fig. 1-Fig. 4; A kind of backlight screen of the utility model preferred embodiment with 6 LED lamp; Comprise LGP, FPC soft board backlight, following diffusion barrier; Wherein at following evenly distributed 6 LED between diffusion barrier and the LGP, said LED is connected on the mainboard and touch-screen of backlight screen through FPC soft board backlight.

Preferably, said backlight screen is the mobile phone touch-screen.

In addition, said 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 utility model is primarily aimed at the improvement that the LED-backlit screen is carried out; The above is merely the utility model preferred embodiment; Non-so promptly limit to the claim of the utility model; So the simple and easy variation and the equivalent transformation of doing with the utility model instructions and graphic content such as all should be contained in the claim of the utility model.

Claims

1. the backlight screen with 6 LED lamp comprises LGP, FPC soft board backlight, following diffusion barrier, it is characterized in that:

At following evenly distributed 6 LED between diffusion barrier and the LGP, said LED is connected on the mainboard and touch-screen of backlight screen through FPC soft board backlight.

2. the said backlight screen of claim 1, wherein said backlight screen is the mobile phone touch-screen.
