Abstract

The present application belongs to the technical field of displays. Disclosed are a display module and a display apparatus. The display module comprises: a display panel, an adhesive layer, and a backlight module. In a frame body in the backlight module, a retaining wall is arranged on the side of a support platform that is away from a bearing face of a bearing platform; and during the process of adhering the display panel to the frame body by means of the adhesive layer, the resin flow amount of a resin flow applied to a display region of the display module in the adhesive layer can be suppressed by means of the retaining wall, such that the maximum width of the cross section of a resin flow portion, which is subsequently formed in the adhesive layer, is relatively small. Therefore, light emitted to each pixel among light emitted by a backlight module can be normally emitted from the corresponding pixel. In this way, the probability of the adverse phenomenon of dark lines occurring in an edge portion of a picture displayed in a display panel can be effectively reduced, such that the display effect of the display panel can be effectively improved.

Abstract

An eyepiece system (10) and a near-eye display device. The eyepiece system (10) comprises a plurality of lenses sequentially arranged along the same optical axis from an image side to an object side, the refractive indexes of the plurality of lenses are all greater than 1.65, and the total track length (TL) of the plurality of lenses along a main optical axis is less than or equal to 25 mm. Given that the eyepiece system (10) has high refractive power, the total track length of the plurality of lenses is reduced, thereby ensuring that the eyepiece system (10) has a relatively high imaging quality and also achieving the miniaturization of the eyepiece system (10).
