Problems solved by technology

However, in fact, this combined display device cannot achieve a borderless display effect very well.
Since the prism-shaped magnifying body 2 has inclined parts protruding from both sides of the display device, the prism-shaped magnifying body 2 is likely to interfere with the display glass of the display device, which not only fails to achieve borderless display, but also seriously affects the display effect

Embodiment 1

[0022] refer to figure 2 , the frameless display device of the present invention comprises a display device 10, a lens group 20 and a transparent material layer 30 arranged between the lens group 20 and the display surface of the display device 10, the outer surface of the lens group 20 is a curved surface, and the transparent material layer 30 At least completely cover the display surface of the display device 10 .

[0023] The lens group 20 has a high transmittance in the wavelength range of visible light, and by designing the curvature of its outer surface, a curved surface with a relatively small curvature can reduce the risk of image distortion. Since the outer surface of the lens group 20 is a curved surface, there is a layer of transparent material layer 30 between the display device 10 and the lens group 20, the probability of interference in the display device is greatly reduced, and the light emitted from the edge of the lens group 20 diverges after being refracted....

Embodiment 2

[0027] Such as image 3 As shown, different from Embodiment 1, the frameless display device of this embodiment has a frame 50, but the displayed picture does not display a frame. Specifically, the frame 50 is closely attached to the end faces of the display device 10 and the lens group 20. The curved surface of the top surface of the group 20 protrudes from the frame 50 , so that the light at the edge of the display device 10 is refracted by the lens group 20 to cover the frame 50 to achieve a frameless effect.

[0028] Here, a stepped portion 51 is provided on the inner wall at the top of the frame 50. The bottom surface of the lens group 20 has the same size as the display surface. Sticking in the step portion 51 , the lens group 20 , the display device 10 and the frame 50 can fit together well. The flange 21 can be formed by grinding, preferably, the angle θ between the end surface and the bottom surface of the lens group 20 is not less than 90°, so as not to affect the di...

Abstract

The invention discloses a frame-free display device. The frame-free display device comprises a display unit, a lens assembly, and a transparent material layer arranged between the lens assembly and the display surface of the display unit, wherein the outer surface of the lens assembly is a curved surface, and the transparent material layer at least completely covers the display surface of the display unit. By arranging the transparent material layer between the display unit and the lens assembly, making the outer surface of the lens assembly into the curved surface and making the transparent material layer completely cover the display surface of the display unit, the frame-free display effect is obtained in the true sense, interference is avoided, and display effect is guaranteed. Meanwhile, due to the fact that an upper polaroid of the display unit is attached to the curved surface of the lens assembly, the situation that in the prior art, a lens assembly is directly attached to an upper polaroid of display glass to cause damage to the polaroid is avoided.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a frameless display device. Background technique [0002] With the development of science and technology, more and more users use liquid crystal display devices, so people's requirements for the quality of liquid crystal display devices are also getting higher and higher. At present, the homogeneity of liquid crystal display devices of various manufacturers is becoming more and more serious, which makes people mainly pursue a larger effective display area for the sake of differentiation and experience. [0003] In order to meet the needs of users, there are even completely borderless display technologies on the market, such as figure 1 As shown, this technology is specifically to attach a layer of inverted trapezoidal prism-shaped magnifying body 2 on the display surface of the display device 1, and at the same time, a protective frame 3 is installed outside the display...
