Problems solved by technology

However, for the manufacture of large-sized display panels, there are still some manufacturing process problems to be overcome
Taking the straight lamp tube in the direct-lit backlight module as an example, when the size of the display becomes larger, the required length of the lamp tube must be increased, and these long lamp tubes are too long during transportation or assembly, so Easily broken and damaged
In addition, these long lamp tubes are not made in general specifications, so the manufacturing process of the lamp tubes will inevitably become more cumbersome and the price will be higher
In addition, when the size of the display becomes larger, it also means that the number of lamps required must increase, so more power must be provided to maintain the operation of the display

Abstract

The back light module includes frame, U-shaped lamp tube and diffusion board. The U-shaped lamp tube is configured inside the frame and has its two electrode ends towards the frame below the U-shaped lamp tube. The diffusion board is configured inside the frame and located over the U-shaped lamp tube. Utilizing the U-shaped lamp tube as light source of the back light module can reduce the number of the lamp tubes in use and lower power consumption.

Description

technical field [0001] The invention relates to a backlight module, and in particular to a backlight module which can reduce the number of required lamp tubes and reduce energy consumption. Background technique [0002] In order to match the modern life style, the volume of video or image devices is becoming thinner and lighter. Although the traditional cathode ray display (CRT) still has its advantages, due to the structure of the internal electronic cavity, the display is bulky and takes up space, and there are still problems such as radiation damage to the eyes when displaying. Therefore, flat panel displays (Flat Panel Displays), such as liquid crystal displays (LCDs), organic light-emitting displays (OLEDs), or plasma displays (Plasma Display Panels, PDPs), which are developed in conjunction with optoelectronic technology and semiconductor manufacturing technology, have gradually become a display The mainstream of the product. [0003] Based on the above, as far as li...
