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.

The driving circuit (100) comprises a level conversion unit (10) and a gate driving unit (20), wherein the level conversion unit (10) comprises a plurality of first clock signal input ends (101) and a plurality of first clock signal output ends (102), and is configured to respectively provide, at the plurality of first clock signal output ends (102), a plurality of first output signals to the gate driving unit (20); and the gate driving unit (20) comprises a plurality of second clock signal input ends (201) and 2n gate signal output ends (202). The gate driving unit (20) is configured to: in response to a first part of the first output signals received by a first part (211) of the plurality of second clock signal input ends (201) at a first moment, sequentially output, in a shifting manner, a plurality of first gate scanning signals at a first part (212) of the 2n gate signal output ends (202); and in response to a second part of the first output signals received by a second part (221) of the plurality of second clock signal input ends (201) at a second moment, sequentially output a plurality of second gate scanning signals at a second part (222) of the 2n gate signal output ends (202). By means of the driving method, the problems of serial display, display errors, etc. can be alleviated.

Abstract

Embodiments of the present disclosure provide a display module. A reflective sheet comprised in the display module is provided between a backplate and a light guide plate. A plurality of light-emitting assemblies are provided at the circumferential edge of the light guide plate. Each light-emitting assembly comprises a light-emitting member, a substrate, and an optical adhesive layer, wherein the light-emitting member is fixed on the substrate. The substrate is adhered to a first surface of the light guide plate by means of the optical adhesive layer, the light-emitting member is located at the circumferential edge of the light guide plate, and a light-emitting surface of the light-emitting member is in contact with the edge of the light guide plate, wherein the first surface is the surface opposite to a light exit surface of the light guide plate. The end portion of the substrate is connected to the surface of the reflective sheet having an edge close to the light guide plate. In this way, the light-emitting member forms a whole with the light guide plate, and can move along with the light guide plate if thermal expansion and cold contraction occur in the light guide plate; in addition, no gap is present between the light-emitting surface of the light-emitting member and the light guide plate, so that light of the light-emitting member can be completely absorbed by the light guide plate, thereby ensuring the effectiveness and uniformity of picture brightness of the display module.
