Description

TECHNICAL FIELD

[0001] The utility model relates to an automobile display system, in particular to a structure of automobile display screen. BACKGROUND

[0002] With the development of automobile technology, especially the popularization of new energy vehicles, display screen has become an increasingly important component in the automobile. In order to improve the sense of technology and aesthetics, the display screen needs to minimize the black edge width of the edge, and improve the screen ratio. However, due to the structure design and material selection of the current vehicle display screen, part of the light P emitted by the LED lamp bead 102 on the PCB board 101 will be blocked by the black film support 105 after passing through the diffusion plate 103 and the optical film 104, as shown in Figure 1 , thereby forming a large-size black edge at the edge of the display panel 106 and the glass 107, as shown in the area L in Figure 1 , the size of this area can only be 6.5mm at the narrowest in the current vehicle display screen, which obviously cannot meet the needs of modern automobile display screen. INVENTION CONTENTS

[0003] The utility model aims at providing a narrow frame display screen structure with smaller edge size, so as to improve the screen ratio of the vehicle display screen and improve the sense of technology and aesthetics of the vehicle display screen.

[0004] The narrow frame display screen structure comprises a rear shell, a circuit board with LED lamp beads installed in the rear shell, an optical film, a film support, and a display panel. The film support comprises a support frame arranged annularly below the edge of the display panel, and the side of the support frame facing the optical film is covered with a reflective paper. The inner side of the annular support frame extends obliquely towards the direction of the optical film, and the side of the support inner frame facing the display panel is obliquely arranged and can reflect part of the light. The light emitted by part of the LED lamp beads is reflected to the edge of the display panel after being reflected by the reflective surface and then being reflected by the reflective paper.

[0005] Further, the inner side of the rear shell is provided with a step located below the edge of the display panel, and all or part of the bottom surface of the support frame is pressed on the step, and the reflective paper extends to the side surface of the support frame through the step.

[0006] Further, the step of the rear shell is provided with a plurality of upwardly protruding bosses arranged at intervals in the annular direction, and the side edges of the support frame extend between each adjacent boss.

[0007] Further, the top surface of the support frame is provided with a groove with a thickness consistent with that of the reflective paper, and the reflective paper extends from the side surface of the support frame to the groove.

[0008] Further, the side of the film pressing support facing the LED lamp bead is parallel to the surface of the optical film.

[0009] Further, the film pressing support is made of transparent material.

[0010] Further, the film pressing support and the display panel are connected by transparent fixing glue.

[0011] Further, the transparent fixing glue is annular and arranged on the top surface of the support frame.

[0012] The narrow frame display screen structure sets the film pressing support on the vehicle-mounted display screen as annular, the outer side of the film pressing support is a support frame and the inner side is a support inner frame; wherein the support frame is arranged below the edge area of the display panel, and the support inner frame extends to below the display area of the display panel, and the inclined surface of the support inner frame, i.e. the side facing the display panel, is a reflective surface. When the LED lamp bead on the PCB board works and the light is shot to the support inner frame, part of the light will penetrate the support inner frame and be shot to the display area of the display panel, and finally form an image at the glass surface; at the same time, part of the light will be reflected to the reflective paper by the reflective surface of the support inner frame, and then be shot to the edge area of the display panel through the reflective paper, so as to light up the edge position of the display screen. Through the narrow frame display screen structure, not only the image at the middle position of the display screen can be lighted up, but also the image at the edge position can be lighted up, so as to increase the bright area, effectively reduce the frame size, and improve the science and technology and aesthetics of the vehicle-mounted display screen; in order to meet the uniformity of the overall display area, the inclination angle of the light emitting surface of the film pressing support can be adjusted as needed, so that the brightness of the edge position is the same as that of the middle display area; in addition, because the light is dispersed into two parts by the film pressing support, the brightness of the two parts will be reduced, which can be solved by appropriately adjusting the brightness or number of the LED lamp beads around, or the brightness of the light around the optical film points can be improved by encrypting the diffusion plate, so as to ensure the final display effect of the display screen.
