FIELD

The subject matter herein generally relates to display devices.

BACKGROUND

More and more display devices have a touch function. The display device with touch function includes a touch module, a display module, and front and rear housings for fixing the touch module and the display module, respectively. Therefore, when the touch module and the display module need to be repaired or replaced, the front and rear housings need to be removed before the touch module and the display module can be removed. In addition, the display module and the touch module are respectively attached to opposite sides of a glass, and the glass is bonded together by a high-strength glue. Therefore, disassembly and replacement of the touch module, the display module, and the glass are complicated.

At least two opposite ends of the glass130are received in the glass receiving groove50. One end of the glass130faces the buffer61. The signal light1201faces the glass130.

The display module140is fixed to the fastening portion211of the inner frame20by a plurality of fixing clamps170facing the glass130. A third foam64is formed between the display module140and the glass130.

The optical refractive strip150is fixed on the first side111of the outer strip11and is attached to the glass130. The optical refractive strip150includes a refractive surface1501, and the signal light1201faces the refractive surface1501. In one embodiment, an angle between the refractive surface1501and the first side111is an obtuse angle. The optical refractive strip150is adjacent to the anti-lock block114.

The filter strip160is fixed on the first side111of the outer strip11and faces the refractive surface1501. The optical refractive strip150is located between the anti-lock block114and the filter strip160. A second foam63is attached between the filter strip160and the glass130, and the second foam63is used to buffer an impact force between the filter strip160and the glass130. The filter strip160filters stray light in an optical signal emitted by the signal light1201.

The optical signal emitted by the signal light1201passes through the glass130to the refractive surface1501of the optical refractive strip150. After refracting off the refractive surface1501, a direction of the optical signal is bent 90 degrees, thereby effecting exchange of optical signals.

The fixing clamp170is fixed to one end of the display module140and the fastening portion211of the inner strip21by screws.

In assembly of the display device100, the buffer61and the first foam62are respectively attached to the anti-lock arm214and the receiving portion212of the inner strip21. Then, the touch module120is inserted into the touch module receiving groove217. Then, the four inner strips21are connected end to end by the four corner fixing members22to form the inner frame20. Then, the inner frame20is placed on the glass130. The anti-lock arm214of the inner frame20encloses an outer periphery of the glass130. Then, the optical refractive strip150and the filter strip160are attached to an inner wall of the first side111of the outer frame10, and the second foam63is attached to a surface of the filter strip160facing the glass130. The optical refractive strip150is located between the anti-lock block114and the filter strip160. The optical refractive strip150is adjacent to the anti-lock block114, and the refractive surface1501faces the signal light1201of the touch module120. Then, the outer strip11is mounted to the inner frame20and fixed by screws. The anti-lock arm214is inserted into the anti-lock slot115. Next, a third foam64is attached to a surface of the glass130away from the first side111, and the display module140is mounted on the glass130. The display module140is fixed to the fastening portion211of the inner strip21by the fixing clamp170. Finally, the four outer corner covers40are mounted to the four corners of the inner frame20, thereby completing assembly of the display device100.

If the glass130, the touch module120, or other components need to be repaired or replaced, the display device100is disassembled in a reverse order of assembly.

The display device100as described above has the following features. First, one end of the glass130is clamped between the inner frame20and the outer frame10, and the inner frame20is movably coupled to the outer frame10. Thus, if the glass130or the touch module120needs to be replaced or repaired, the inner frame20and the outer frame10can be directly disassembled, so that the glass130or the touch module120can be quickly disassembled and replaced. Second, the anti-lock slot115is located on the outer frame10, and the anti-lock arm214matching the anti-lock slot115is located at an end of the inner frame20facing the glass130. The anti-lock arm214encompasses the end of the glass130and is inserted into the anti-lock slot115to prevent the outer frame10from being stretched. Third, the touch module120inserted into the inner frame20can reduce a volume of the display device100. Fourth, the optical refractive strip150is arranged on the first side111facing the signal light1201to change and optimize a transmission path of the optical signal.
