Each inverted U-shaped lamp cavity 1122 is configured with a lamp bead 117, and the light emitting of the lamp bead 117 is guided individually through the inverted U-shaped lamp cavity 1122 to improve the light guiding effect. Preferably, a plurality of parallel V-shaped grooves 1123 are arranged on the top of the inverted U-shaped lamp cavity 1122, which improves the light guiding effect and increases the light guiding range.

[0030] The light-emitting assembly composed of the light homogenizing film 113, the transparent acrylic plate 114 and the film 115 is arranged on the light-emitting side of the light guide cover 112; the light homogenizing film 113 is attached to the side of the transparent acrylic plate 114 adjacent to the light guide cover 112, and the film 115 is attached to the side of the transparent acrylic plate 114 adjacent to the semi-transparent black acrylic plate 116. As shown in Figure 2 the film 115 is divided into the black light-proof area 115A and the light-transmitting area 115B, and a plurality of gradient color balls 118 are printed in the light-transmitting area 115B, and each gradient color ball 118 is arranged in pairs with a lamp bead 117. The gradient color ball 118 is gradually colored from the center to the circumference, that is, the color is gradually changed in the radial direction.

[0031] The semi-transparent black acrylic plate 116 is arranged on the light-emitting side of the film 115.

[0032] After the display device is started, the light emitted by the lamp bead 117 is guided by the light guide cover 112, homogenized by the light homogenizing film 113, and then projected onto the film 115 through the transparent acrylic plate 114, and is emitted from the light-transmitting area 115B of the film 115, so that the gradient color balls 118 in the light-transmitting area 115B display the effect of the stereoscopic small balls, thereby increasing the visual recognition rate. Compared with the built-in display of the existing eye detection equipment, the display device provided in the application has the advantages of simple structure, low cost and the like, and can reduce the cost of the hardware configuration of the eye detection equipment main body.
