Abstract
The invention discloses a display device which comprises a backlight module used for providing backlight; a display panel located on the light emitting side of the backlight module and used for image display, wherein the backlight module comprises a back plate which has supporting and bearing effects; a light bar positioned on the back plate; a reflector plate positioned on one side, deviating from the back plate, of the light bar, wherein the light bar comprises a circuit board used for providing a driving signal; and a light-emitting device located on the circuit board, wherein the width of the light-emitting device in the direction perpendicular to the light bar extending direction is larger than that of the circuit board in the direction perpendicular to the light bar extending direction. ,The reflector plate comprises a plurality of openings for exposing the light-emitting devices, the size of the openings is larger than that of the light-emitting devices; and a first reflective layer is arranged on the back plate exposed by the opening. The first reflective layer has the function of reflecting light, and even if the light is incident on the back plate in the opening, the light can be reflected to the light emitting side by the first reflective layer, so that the loss of the light can be avoided, and the optical efficiency is improved.
Description
technical field [0001] The present invention relates to the field of display technology, in particular to a display device. Background technique [0002] The liquid crystal display panel is a non-self-illuminating display panel, and needs to cooperate with a backlight module to provide backlight to realize image display. Backlight modules are divided into direct-type backlight modules and side-type backlight modules according to their structural forms. Direct-lit backlight modules are widely used in LCD TVs due to their advantages such as good light-emitting viewing angle, high utilization rate, simple structure, and low cost. [0003] In order to improve the utilization rate of the light source, in the direct-type backlight module, a reflective sheet is usually arranged on the light emitting side of the light source, and the opening on the reflective sheet exposes the light source. In this way, the reflected light after the light emitted by the light source enters the opt...
