In technique scheme, the light-emitting section being arranged on light guide plate side provides light source, radium-shine lamp holder for radium-shine lamp holder
Uniformly injecting light beam from the side of light guide plate, the effect of limited block is to limit between light guide plate and backboard lower baffle plate, and limit
Keep suitable gap between light guide plate processed and radium-shine lamp holder, prevent in the light guide plate course of work due to fever expansion, cause
Come in contact between tabula rasa and radium-shine lamp holder or lower baffle plate, cause light guide plate or radium-shine lamp holder to damage.
Preferably, the gap of 2-5mm is kept between the bottom of described light guide plate and lower baffle plate.
Preferably, the gap of 2-5mm is kept between the side of described light guide plate and radium-shine lamp holder.Through experiment discovery light guide plate
After being heated expand ultimate range be less than 1.6mm, it is thus determined that the safe distance of 2-5mm enough ensure light guide plate not with radium
Shot-light head and lower baffle plate touch.Distance between light guide plate and radium-shine lamp holder and lower baffle plate is unsuitable excessive simultaneously, otherwise can increase
The size of display, increases the length of frame.
Preferably, the distance between described radium-shine lamp holder is 5-20mm.It through the distance between the radium-shine lamp holder of experiment discovery is
During 5-20mm, the distribution ratio entering light inside light guide plate is more uniform, and the display effect of display is preferable.
Further, when the distance between described radium-shine lamp holder is 10mm, the distribution entering light inside light guide plate is the most equal
Even, the display of display is best.
Relative to prior art, the light guide plate of a kind of liquid crystal display of the utility model offer and light-emitting section mounting structure
Have the beneficial effects that: 1) ensure to keep enough between light guide plate and light-emitting section, light guide plate and backboard by arranging limited block
Gap, damages after preventing light guide plate expanded by heating；2) this mounting structure is by the distribution of radium-shine lamp holder on optimized emission bar, permissible
Ensure that light guide plate side enters being uniformly distributed of light.
