Backlight module and flat panel display
InactiveUS20080062722A1Reduce poor displaying phenomenonIntensive stress forcePlanar/plate-like light guidesNon-linear opticsDisplay deviceFlat panel display
The backlight module in the flat panel display (FPD) includes a frame that resides between the backlight module and the cover of FPD display, and has an inclined plane with an angle between the optical film. The inclined plane causes the touching area broader than the parallel plane does, thus it will absorb more stress force and avoid displaying defects in the FPD panel. Using this structure, the pressure transformed from the FPD cover stresses the inclined plane and forces it to contact the FPD's back light module on broader area in reducing the pressure per unit's area.
