Backlight module introduction

Backlight module is one of the key components of LCD panel . The function is to supply sufficient brightness and evenly distributed light sources , Enable it to display images normally .

Backlight module （Back light module) LCD panel （LCD panel) One of the key components of , Because the liquid crystal itself does not emit light , The function of the backlight module is to supply sufficient brightness and evenly distributed light sources , Enable it to display images normally .

LCD Panels are now widely used in monitors 、 laptop 、 Digital cameras, projectors and other electronic products with growth potential , Therefore, the demand for backlight modules and their related components continues to grow , Stimulated by the low price of the panel , And notebook computers and LCD Large size panels such as monitors are in greatest demand , It is the main power source for the growth of backlight module demand .

Basic structure of backlight group

At home LCD Panel manufacturers are actively expanding their production , The domestic demand market continues to expand , As the backlight modules produced by domestic manufacturers have reached the same level as those produced by large international manufacturers , Plus the advantages in mass production scale and local supply , The self-sufficiency rate of domestic backlight modules will be further improved .

It is mainly composed of a light source （Light source) 、 Light guide plate （light guide plate) 、 Plastic frame （housing) 、 Reflector （Reflector) 、 Diffuser （Diffuser) 、 Brightening sheet （BEF、 Prism piece ）、 Black and white glue （Curtain Tape) etc. .

As the backlight is required to be thinner and thinner , So some parts need iron frames （METALFRAME)

Application field

LCD The panel is mainly composed of color filters 、 Backlight module 、 drive IC、 Compensation film and polarizing plate 、 Glass substrate 、ITO membrane 、 Alignment membrane 、 Control circuit and other components , Because the liquid crystal panel itself does not have luminous characteristics , The display function must be achieved with the help of the backlight module .
