Glue line is respectively equipped between glass substrate and the second polaroid to be bonded, and is sealed between first and second glass substrate by LCD
Glue is sealed with liquid crystal layer, and the backlight module includes blooming piece, light guide plate, the brightness enhancement film of high brightness and light successively from top to bottom
Reflector plate is learned, is mutually bonded by double faced adhesive tape between blooming piece, light guide plate, brightness enhancement film and optical reflection piece, light guide plate enters light
Side is welded with LED lamp source.OCA optical cement advantages are clarity, high light transmittance (full light transmittance>99%), high adhesion, its phase
Than common bonding mode, the light transmittance of light is substantially increased.
Further, the LED lamp source is high-brightness LED lamp source, it is preferred to use the high-brightness LED lamp source of Japanese day Asia.
Further, the glue line material is also OCA optical cements.
According to above-mentioned technical proposal, compared with prior art, OCA optical cement layers are provided between liquid crystal panel, backlight module,
Using the characteristic of OCA optical cements, the light transmittance of light is substantially increased, increases the blast of high brightness on the basis of optical reflection piece
Film, the reflectivity that LED lamp source is irradiated to after optical reflection piece is improved, improve the backlight illumination of whole backlight module, energy
Enough effectively improve the visual performance of LCDs, meet outdoor display device to display screen the visual performance under strong light environment
It is required that.
