Display module

Abstract

A display module includes an outer frame, a light emitting unit, a panel device, and a light guide plate having a light entrance surface, a light exit surface, and a connecting side. A connecting ear portion is extendedly formed from the connecting side for extending into the outer frame to fix the light guide plate onto the outer frame. The light emitting unit is disposed in the outer frame corresponding to the light entrance surface for emitting light into the light guide plate via the light entrance surface. The panel device is disposed on the light guide plate and contained in the outer frame for receiving light emitted from the light guide plate. The connecting ear portion is away from the light exit surface by a vertical distance, and the ratio of the length of the connecting ear portion to the length of the connecting side is greater than 0.2.

What is claimed is: 
     
         1 . A display module comprising:
 an outer frame;   a light guide plate having a light entrance surface, a light exit surface, and at least one connecting side, at least one connecting ear portion being extendedly formed from the connecting side for extending into the outer frame to fix the light guide plate onto the outer frame;   at least one light emitting unit disposed in the outer frame corresponding to the light entrance surface for emitting light into the light guide plate via the light entrance surface; and   a panel device disposed on the light guide plate and contained in the outer frame for receiving the light emitted from the light guide plate;   wherein the connecting ear portion is away from the light exit surface by a vertical distance, and the ratio of the length of the connecting ear portion to the length of the connecting side is greater than 0.2.   
     
     
         2 . The display module of  claim 1 , wherein the outer frame has a connecting slot corresponding to the connecting ear portion, and the connecting ear portion extends into the connecting slot to be connected to the outer frame. 
     
     
         3 . The display module of  claim 1 , wherein the light guide plate further has a reflection bottom surface opposite to the light exit surface, the connecting ear portion is connected to the reflection bottom surface, the outer frame has a connecting slot corresponding to the connecting ear portion, and the connecting ear portion extends into the connecting slot to be connected to the outer frame. 
     
     
         4 . The display module of  claim 3 , wherein the connecting ear portion has an upper surface, the connecting slot has a lower surface opposite to the upper surface, and the display module further comprises a first adhesive tape attached between the upper surface and the lower surface. 
     
     
         5 . The display module of  claim 4 , wherein the connecting ear portion further has a first side surface, the connecting slot further has a second side surface opposite to the first side surface, the display module further comprises a light shielding tape, and the light shielding tape extends from an end of the first adhesive tape and is attached onto at least one of the first side surface and the second side surface. 
     
     
         6 . The display module of  claim 4 , wherein the connecting ear portion further has a bottom surface, and the display module further comprises a second adhesive tape attached between the bottom surface and the outer frame.
