Detailed Description
In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein.
In order to solve the problems as described in the background art, a solution is easily conceived, starting from the conventional idea: two displays of the dual-screen display structure share the same backlight assembly. However, the structure has high requirements on the structure and quality of the backlight assembly and high production cost; the improved thought also leads to that in daily use, once the backlight component is damaged, both the two displays cannot be used, and higher efficiency is achieved due to the need of later maintenance and repair; meanwhile, when any display is used, the backlight component needs to be in a working state, which can greatly affect the service life of the backlight component. Although the above-mentioned improvement idea can solve the problems described in the background art, the drawbacks thereof are greater than those of the prior art, and obviously, the solution cannot be an ideal solution.
Based on the above research findings, the inventor proposes an integrated dual backlight display structure, and the following describes a preferred embodiment of the present invention with reference to the accompanying drawings.
As shown in fig. 1 to fig. 3, for an integrated dual backlight display structure 100 shown in an embodiment of the present application, a first display panel 110 and a second display panel 120 are provided, the first display panel 110 and the second display panel 120 are disposed oppositely, and the first display panel 110 and the second display panel 120 are respectively provided with a corresponding backlight component 130; the backlight assembly 130 includes a back plate 131, and the two backlight assemblies 130 share the back plate 131.
Referring to fig. 4, preferably, in order to save the steps of manufacturing and installing the integrated dual backlight display structure 100, the back plate 131 is an integrated structure. In this embodiment, the back plate 131 is made of a metal material, and the forming method is integral die-casting.
It should be noted that the backlight assembly 130 is a component capable of supplying a sufficient brightness and a light source with uniform distribution, and is capable of enabling the first display panel 110 and the second display panel 120 to normally display images.
It should be noted that the back plate 131 serves as a common component of the two backlight units 130, and has a supporting function. That is, the first display panel 110 and the second display panel 120 are respectively connected to other components of the backlight assembly 130, and then are mounted and supported on two sides of the back plate 131.
The integrated double-backlight display structure 100 of the scheme shares the back plate 131 with the backlight component 130 of the first display panel 110 and the second display panel 120, and compared with the situation that two backlight modules are respectively arranged on two display panels in the prior art, the integrated double-backlight display structure saves one back plate 131 component and one structural component for connecting the two display modules, reduces parts of the double-screen display structure, and has the advantages of smaller overall thickness, lighter weight, reduced production cost and improved economic benefit.
Referring to fig. 1 and fig. 2, the backlight assembly 130 further includes an optical film set 134, a light guide plate 133 and a light emitting bar 132, wherein the optical film set 134, the light guide plate 133 and the light emitting bar 132 are sequentially disposed from the first display panel 110 or the second display panel 120 to the back panel 131. That is, each of the backlight units 130 includes an optical film group 134, a light guide plate 133, a light emitting bar 132, and a back plate 131, and the back plates 131 of the two backlight units 130 are the same unit, that is, the other units of the two backlight units 130 are respectively disposed at both sides of the back plate 131, and the units are distributed in a mirror image.
The optical film group 134 (optical film) is mainly used to improve optical efficiency and reduce stray light in an optical system. The optical film group 134 includes a plurality of optical films. The optical film is a material having a microstructure made of a material such as resin on the surface of a base film (PET) to provide a specific optical function.
Specifically, the optical module may include a Brightness Enhancement Film (BEF), a diffusion film, a reflection film, and the like. Specifically, the reflector plate reflects unscattered light sources into the light conduction region in a mirror reflection mode so as to improve the utilization rate of light; a plurality of granular objects are arranged in the diffusion film, so that light received by the light guide plate 133 can be diffused, the light can be transmitted to the bright enhancement film and the front direction of the screen, and the effect of widening the visual angle is achieved; the brightness enhancement film is also called a prism sheet, and focuses diffused light within a certain angle to achieve the purpose of improving the brightness of a screen.
The light guide plate 133 is configured to receive light emitted from the light-emitting bars 132, and convert a linear light source into a planar light source through diffuse reflection of bottom printed dots or injection-molded dots. The method is characterized in that an optical acrylic/PC plate is used, and then a high-tech material with extremely high refractive index and no light absorption is used for printing light guide points on the bottom surface of the optical acrylic plate. The optical acrylic sheet absorbs the light emitted from the light source to stay on the surface of the optical acrylic sheet, and when the light is emitted to each light guide point, the reflected light is diffused at each angle, and then the reflected light is emitted from the front surface of the light guide plate 133 by destroying the reflection condition. The light guide plate 133 can uniformly emit light through various light guide points with different densities and sizes. The reflective sheet is used to reflect light exposed from the bottom surface back into the light guide plate 133, thereby improving the use efficiency of light; under the condition of equal area brightness, the luminous efficiency is high and the power consumption is low.
In this embodiment, the light guide plate 133 is a flat plate light guide plate, and the molding method is injection molding.

The control board 150 is connected to an external power source and an external signal, and can control the connected light-emitting bars 132.
Referring to fig. 1 and fig. 2, the two control boards 150 are further connected to the first display panel 110 and the second display panel 120 through the flexible printed circuit 140, respectively. The flexible printed circuit 140 is disposed between the control board 150 and the first display panel 110 or the second display panel 120, and plays a role in connection and conduction. The two control panels 150 respectively control the first display panel 110 and the second display panel 120 without interfering with each other, and can respectively control the first display panel 110 and the second display panel 120, so that the display contents in the first display panel 110 and the second display panel 120 can be inconsistent, and the diversity of the display contents can be realized. Meanwhile, once one of the two control boards 150 is damaged, the damaged control board 150 can be repaired and replaced without affecting the other display panel.
In the present embodiment, two control boards 150 are connected below the first display panel 110 and the second display panel 120, respectively. Further, referring to fig. 4, openings 1315 adapted to the flexible printed circuit 140 are disposed on two sides of the back plate 131, so that the flexible printed circuit 140 does not protrude from the outer surface of the back plate 131 in an assembled state, so as to avoid affecting the appearance.
