Problems solved by technology

[0004] However, adding 2 LEDs will increase the power consumption of the mobile phone. The power consumption of 4 LEDs is 3.2v*60mA; the power consumption of 6 LEDs is 3.2v*90mA, which requires the power supply on the motherboard. In addition, it is also necessary to reserve 6LED interfaces for the screen interface and the motherboard interface for matching

Embodiment Construction

[0017] see figure 1 and figure 2 , a backlight screen with 6 LED lamps in a preferred embodiment of the present invention, including a light guide plate, a backlight FPC soft board, and a lower diffusion film, wherein 6 LEDs are evenly arranged between the lower diffusion film and the light guide plate. The LED is connected to the main board and the touch screen of the backlight screen through the backlight FPC soft board.

[0018] Preferably, the backlight screen is a touch screen of a mobile phone.

[0019] In addition, the backlight screen is a touch screen of a mobile phone.

[0020] When the backlight module is in use, the signal level must be output after the positive power supply is stably connected or input signal level after disconnection; when in use, the sequence of connecting the logic power supply and the driving power supply is first the logic power supply and then the driving power supply.

[0021] The present invention is mainly aimed at the improvement of ...

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 [0001] The invention relates to a backlight screen using LED lights as light sources, and further relates to a backlight screen with six LED light sources. Background technique [0002] In recent years, backlights have developed rapidly, and new technologies and products have been launched continuously. LED backlights have gradually entered industrialization and have a certain scale. Compared with CCFL, LEDs have obvious energy-saving advantages. They can be mainly used in computer monitors, Mobile phone displays and so on, but there are still many areas for improvement in LED backlighting. [0003] Now, the backlight device in the display module has been improved from using 4 LEDs to 6 LED lighting. The surface brightness of the group can be increased by about 40% to 60%. Generally, the screen surface brightness of 4 LEDs called ordinary screens is only 180 to 200 cd / mm (square millimeters), while the screen surface of 6 LEDs is called high brightness scree...
