Description

Technical Field

[0001] The utility model belongs to the technical field of display screens, and particularly relates to a display screen structure. Background Art

[0002] In the existing floating display screen, it is composed of a glass cover plate, a screen module, a bracket and a rear shell. The screen module is a complete structure, including structures such as a TFT screen and a backlight assembly. There is a border of more than 5 mm from the TFT screen to the edge of the module. After the screen module is attached to the rear shell, the glass cover plate needs to have a gap for installing the adhesive surface, and is attached to the bracket or the rear shell. There needs to be a structural gap between the screen module and the bracket. In addition, the rear shell or the bracket needs to protrude 1-2 mm from the glass to ensure that the screen is not easily knocked and broken and the width occupied by other internal structures. Finally, the overall black edge of the display screen is relatively wide and slightly thick, and the thick border width affects the overall appearance improvement of the display screen. Summary of the Invention

The third mounting surface is connected to the circumferential edge of the inner side surface of the glass cover through a structural adhesive.

[0007] With the above further settings, three parallel mounting surfaces are provided on the housing to fixedly mount the backlight assembly, the FOG screen, and the glass cover respectively, making them parallel to each other, which facilitates the positioning of the backlight assembly, the FOG screen, and the glass cover. The backlight assembly, the FOG screen, and the glass cover can be sequentially bonded and installed from the inside out, with simple installation and neat appearance.

[0008] Further setting of the present utility model: An explosion-proof film and a protective film are sequentially provided on the outer side of the glass cover.

[0009] With the above further settings, the explosion-proof film and the protective film further prevent the glass cover from being worn or even broken.

[0010] Further setting of the present utility model: An outer shell is provided behind the housing, and a PCBA is fixedly provided on the outer shell.

[0011] With the above further settings, the PCBA is used to connect and control the backlight assembly, and the outer shell is used to protect the PCBA and the housing to prevent the housing from being damaged and affecting the glass cover, the FOG screen, and the backlight assembly.

[0012] Further setting of the present utility model: The optical adhesive layer uses OCR material.

[0013] With the above further settings, the OCR material is an optically transparent resin, an adhesive for bonding transparent optical elements. It is colorless and transparent, has an extremely high light transmittance, and has chemical properties such as good bonding strength, small curing shrinkage rate, resistance to yellowing, and relatively soft hardness, and is used to fix the FOG screen and the glass cover.

[0023] As Figures 1-4 shown, a display screen structure includes a housing 13. Three backlight assemblies 1 are provided on the housing 13. Each backlight assembly 1 includes a light guide plate 12. A FOG screen 3 and a glass cover 2 are provided outside each light guide plate 12. The light guide plate 12, the FOG screen 3 and the glass cover 2 are arranged on the housing 13 from the inside to the outside. The housing 13 is provided with three parallel stepped surfaces from the inside to the outside, including a first mounting surface 14 for mounting the backlight assembly 1, a second mounting surface 15 for supporting and fixing the FOG screen 3, and a third mounting surface 16 for fixedly mounting the glass cover 2. The second mounting surface 15 is connected to the circumferential edge of the inner side surface of the FOG screen 3 through a sealing strip 10. The third mounting surface 16 is adhered to the circumferential edge of the inner side surface of the glass cover 2 through a structural adhesive 5. Three parallel mounting surfaces are provided on the housing 13 to fixedly arrange the backlight assembly 1, the FOG screen 3 and the glass cover 2 respectively, so that the light guide plate 12, the FOG screen 3 and the glass cover 2 are parallel to each other, which is convenient for positioning the backlight assembly 1, the FOG screen 3 and the glass cover 2 on the housing 13, and the backlight assembly 1, the FOG screen 3 and the glass cover 2 can be sequentially attached and installed from the inside to the outside, with simple installation and neat appearance.

[0024] The FOG screen 3 is connected to the glass cover 2 through the optical adhesive layer 4. The optical adhesive layer 4 can be made of OCR material. As an adhesive for bonding transparent optical components, it is colorless and transparent, has a very high light transmittance, and has chemical properties such as good bonding strength, small curing shrinkage rate, yellowing resistance, and relatively soft hardness. It is used to paste and connect the FOG screen 3 and the glass cover 2.

[0025] There is a gap between the FOG screen 3 and the light guide plate 12, which can be used to optimize light propagation, reduce light loss, and improve the display effect.

[0026] An explosion-proof film 6 and a protective film 7 are sequentially pasted on the outer side of the glass cover 2 to prevent the glass cover 2 from being worn or even broken.

[0027] An outer shell 8 is provided behind the housing 13. The front side of the housing 13 is used to arrange the backlight assembly 1, the FOG screen 3, and the glass cover 2. The back side thereof can be provided with screw buckles to connect the outer shell 8. There is enough space in the outer shell 8 to arrange three PCBAs 9. The three PCBAs 9 are all fixed to the housing 13 by screws. The three PCBAs 9 respectively control the three backlight assemblies 1.
