Abstract: A polarizing plate includes a first substrate layer, a polarizing layer, a second substrate layer, a pressure sensitive adhesive layer and a light-shielding pattern. The polarizing layer is disposed on the first substrate layer. The second substrate layer is disposed on the polarizing layer, whereby the polarizing layer is located between the first substrate layer and the second substrate layer. The pressure sensitive adhesive layer is formed on a bottom surface of the first substrate layer, whereby the first substrate layer located between the polarizing layer and the pressure sensitive adhesives layer. The light-shielding pattern is formed between the second substrate layer and the pressure sensitive adhesives layer.

Abstract: A light guide plate comprises two supporting bars and a light transmission plate. Each of the supporting bars includes a wall and a first supporting protruded element. Each of the walls has a wall surface, which face each other. Each of the first supporting protruded elements is connected to one of the walls, and is protruded outside the wall surface. The light transmission plate has a light exiting surface, a light entering side surface and a bottom surface. The light exiting surface is disposed oppositely to the bottom surface, and the light entering side surface is connected between the light exiting surface and the bottom surface. The light transmission plate is connected between the supporting bars. Each of the first supporting protruded elements is disposed above the light exiting surface, and a first gap is disposed between each of the first supporting protruded elements and the light exiting surface.

Abstract: An optical touch display device is provided. The optical touch display device includes a front frame, a light guide strip, a photosensitive element, and a light source. The front frame includes a body portion having a display opening, at least one positioning board located on a corner of the body portion, and a protecting cover located on the body portion. An end of the protecting cover is adjacent to the positioning board. An opening groove is defined between the protecting cover and the body portion. The body portion, the positioning board, and the protecting cover are integrally formed. The light guide strip is placed in the opening groove. The photosensitive element is fixed on the positioning board. The light source is located between the photosensitive element and the light guide strip, and a light-emitting side of the light source faces a light inlet side of the light guide strip.

Abstract: A display panel includes a frame, a panel body, and at least two elastic buffer members. The frame includes a frame body and a frame plate with a plane and an opening. The opening is located in the plane. The frame body is disposed on the plane and surrounds the opening. The panel body is disposed on the plane and covers the opening. The elastic buffer members are face to face disposed on the plane. The frame body surrounds the panel body and the elastic buffer members. Each elastic buffer member includes a stop block and a support plate with a contact plane facing the panel body. The support plate is connected between the stop block and the frame plate. The stop block protrudes from the contact plane. The panel body is located among the elastic buffer members and disposed between the stop blocks and the plane.
