Embodiment Construction

[0040] figure 1 is a schematic oblique view of a display device according to an embodiment of the present invention.

[0041] Please refer to figure 1 , in this embodiment, the display device 10 includes a display module 100 and a backlight module 200 , wherein the backlight module 200 is stacked on the display module 100 in a first direction. The backlight module 200 includes a light guide plate 210 , a plurality of light sources 220 and a first prism sheet 230 .

[0042] In this embodiment, the light guide plate 210 has a light incident surface I, a bottom surface B, and a light exit surface E opposite to the bottom surface B. As shown in FIG. The light guide plate 210 , the first prism sheet 230 and the display module 100 are stacked and disposed along the first direction D1 , in other words, the first direction D1 is substantially perpendicular to the light emitting surface E. In some embodiments, the bottom surface B and / or the light-emitting surface E of the light gui...

Abstract

A display device includes a display module and a backlight module. The backlight module is stacked on the display module. The backlight module includes a light guide plate, a plurality of light sources and a first prism sheet. The light guide plate has a light incident surface, a bottom surface and a light exit surface opposite to the bottom surface. The first direction is perpendicular to the light-emitting surface. The light source is arranged on the light incident surface. There is the shortest distance between the light source and the light guide plate in the second direction. The light sources are arranged along the third direction. The first prism sheet is arranged on the light emitting surface. The first prism sheet has a plurality of first convex structures. The refractive index of the first protrusion structure is greater than or equal to 1.6. A light provided by the light source passes through the light guide plate.

Description

technical field [0001] The invention relates to a display device, and in particular to a display device with a backlight module. Background technique [0002] With the advancement of science and technology, electronic products play an increasingly important role in human life, and mobile phones, computers, TVs, smart watches... and other products have more and more functions. However, energy consumption is required when using various functions of electronic products. Therefore, how to reduce the energy consumption of electronic products has become an urgent problem to be solved by all walks of life. [0003] In an electronic product equipped with a display device, in order to display images with sufficient brightness, the backlight module of the display device often consumes a lot of energy. In some portable electronic products (such as mobile phones, tablet computers, etc.), if the power consumption of the display device is too high, the electronic products are prone to th...
