Abstract: A backlight module includes a light guide plate, a light source, a fixing element and an elastic element. The light guide plate has a light incident surface. The light source has a light-emitting side and a back side opposite to the light-emitting side, and the light-emitting side faces the light incident surface. The fixing element is disposed to be opposite to the back side. The elastic element is connected to the fixing element, wherein the elastic element is adapted to push the light source to be against the light incident surface.

Abstract: A display device includes a first substrate, a second substrate, an adhesive body and a limiting adhesive tape. The second substrate is disposed to be opposite to the first substrate. The adhesive body is connected to the first substrate and the second substrate. The limiting adhesive tape is disposed on the first substrate and/or the second substrate, and the limiting adhesive tape is covered by the adhesive body.

Abstract: A display device includes a frame body, a positioning unit, a light guide plate, and an elastic unit. The frame body includes a back plat which includes a limiting slot. The positioning includes a loading portion, a side wall portion, and a positioning protrusion. The positioning protrusion is located on the loading portion and extends toward the back plate to fit in the limiting slot. When the elastic unit is in the non-compressed state, one end of the elastic unit abuts against the side wall plate, and the other end abuts against the side wall portion so that the positioning protrusion is at a first position of the limiting slot. When the light guide plate is heated, the positioning protrusion is driven to move to a second position of the limiting slot, and the elastic unit is pressed to be in the compressed state.

Abstract: The display system comprising a main control module and a display module is provided. The main control module comprises a display driving circuit and a timing control circuit. The display driving circuit is used to output a display driving signal. The timing control circuit is coupled to the display driving circuit to receive the display driving signal, and convert the display driving signal into a digital signal. The display module comprises a first display panel to an N-th display panel, coupled to the timing control circuit and receiving the digital signal, so as to display corresponding multimedia content according to the digital signal, wherein N is a positive integer greater than 1, and the main control module is independently coupled to the display module.

Abstract: A display includes a frame body and an optical film. Each of the first side wall and the third side wall of the frame body has a first positioning structure. Two end portions of each of the second sidewall and the fourth sidewall are bent toward the accommodating space to form second positioning structures. The optical film includes first positioning pieces and second positioning pieces. The first positioning pieces are respectively at the first side and the third side of the optical film, and each of the first positioning structures passes through a corresponding one of the first positioning pieces. The second positioning pieces respectively extend along a direction parallel to the first side or the third side of the optical film, and each of the second positioning pieces corresponds to a corresponding one of the second positioning structures.

Abstract: A display includes an outer frame, a supporting frame, a display module, and a covering member. The supporting frame is accommodated in the outer frame. The display module is disposed on a supporting member of the supporting frame. The supporting member extends toward a display region of the display module from the supporting frame. On a first surface of the display module, a projection area of the supporting member and a projection area of an first optical film of the display module are partially overlapped with each other. A third surface of the covering member is closely attached to a second optical film of the display module. The covering member has an extension portion. The extension portion extends from a fourth surface opposite to the third surface toward a direction away from the third surface, and the extension portion is coplanar with the outer side surface of the outer frame.

Abstract: An oral imaging device includes a base, a camera module, and a plurality of light source modules. The base includes a camera component, an opening surface, and a plurality of light source components connected to two sides of the camera component. A slant angle exists between each light source component and the camera component. The slant angle is a non-right angle. The opening surface is substantially parallel to the camera component. The camera module is located on the camera component and faces the opening surface. The plurality of light source modules each are located on each light source component and configured to project a light beam onto the opening surface. A center ray of the light beam passes through a center point of the opening surface.

Abstract: A backlight module includes a case body, supporting structures, light-emitting elements, and an optical module. The case body includes a first side wall and a second side wall opposite to the first side wall. Each of the support structures includes two supporting members and a bearing member. Two supporting members are respectively disposed on the first side wall and the second side wall. Each of the supporting member includes a fitting portion, an extending portion, and a bending portion. The fitting portion is fixed to the first side wall and the second side wall. The bearing member is disposed between the two supporting members. The light-emitting elements are respectively disposed on the bearing surface of the bearing member of the corresponding supporting structures. The optical module is disposed on the extending surface of the extending portion of each of the supporting structures. A display device is also provided.
