The utility model provides a separated LED reflecting film component, because the whole reflecting film adopts a separation structure, even if the auxiliary reflecting film body is pressed by an LED lamp, the pressure is not transmitted to the main reflecting film body, thereby completely avoiding the occurrence of the wrinkling of the reflecting film and improving the reliability of a backlight structure of a mobile phone.
Description
Technical Field
The utility model relates to a mobile phone type backlight structure, in particular to a separated LED reflective film component.
Background
In the conventional backlight structure of mobile phones, as shown in fig. 1 to 6, in order to increase brightness, a reflective film is extended into the bottom of an LED lamp. However, because there is a tolerance between each fitting, the gap between the LED lamp 102 and the reflective film 100 is too small, and after assembly, the LED lamp 102 may be pressed against the reflective film 100, resulting in a problem of wrinkling of the reflective sheet during reliability test.
The Chinese patent document CN109656418A discloses a separated touch display module which is used for being connected with equipment in a separated mode, wherein the equipment comprises a cover plate and a shell, a space for accommodating the touch display module is formed between the cover plate and the shell, and a first low reflection film is adhered to the right side of the cover plate; the separated touch display module comprises a touch layer, optical glue and a display screen which are sequentially stacked from left to right, wherein a second low-reflection film is further arranged on one side surface of the touch layer, which is opposite to the optical glue, and the second low-reflection film is arranged corresponding to the first low-reflection film. The touch layer includes a glass substrate and an ITO film, and a transition film formed between the glass substrate and the ITO film. The glass substrate is arranged on the left side of the touch control layer, and the ITO film is arranged on the right side of the touch control layer. The touch control layer and the low reflection film attached to the touch control layer form a touch control functional layer, and the touch control functional layer and the display screen glued by the optical glue form a touch control display module. And a gap of 0.5mm to 1mm is reserved between the cover plate and the touch display module. A gap of 200 μm or more is provided between the glass substrate and the ITO film.
Obviously, the patent designs the touch display module with small size and the cover plate with large size separately, and then attaches the touch display module and the cover plate when assembling. The structure only solves the laminating problem of the touch screen, but cannot solve the extrusion problem of the reflecting film.
The Chinese patent document CN204943418U discloses a reflecting film structure of a backlight module, which comprises a reflecting film, wherein the reflecting film is provided with four side edges, two symmetrical side edges are respectively stuck with a piece of back glue, the two back glues are mutually separated, and the other two side edges on the reflecting film are left empty. The two sides left on the reflecting film are respectively stuck with a piece of back glue, so that the back glue of the four sides on the reflecting film are connected end to form an annular back glue whole, the annular back glue whole is provided with a breathing notch, and the breathing notch cuts off the annular back glue whole. The annular back adhesive is integrally provided with 1 or more than 1 breathing notch. The annular back adhesive is provided with four breathing gaps, and the annular back adhesive is wholly divided into four sections of back adhesives which are mutually separated by the four breathing gaps. The width of the back adhesive is 0.5-2 mm. The length of the breathing notch is 2-15 mm.
Obviously, the breathing notch is arranged on the back adhesive of the reflecting film, but the problem of extrusion of the reflecting film cannot be solved by the structure.
The Chinese patent document CN102200236A discloses an LED backlight module device, which comprises a metal backboard, a reflecting device, a frame, a group of optical templates and at least one LED light-emitting source, and is characterized in that the bottom of the frame is provided with a bayonet, the metal backboard is provided with a joint part matched with the bayonet, and the metal backboard is movably sleeved with the frame. The frame is rectangular, the bayonet at the bottom of the frame is a flat groove, the metal backboard is a corresponding rectangular plate, and the metal backboard is spliced with the flat groove of the frame. Grooves for accommodating the optical films are respectively arranged on the frame opposite to the optical films. The frame is of a split structure.
It is obvious that this patent only relates to a separate design of the frame and does not relate to an improvement of the structure of the reflective film itself of the LED.

In addition, a reinforcing layer protruding outward may be provided on the surface of the sub-reflecting film body. When the auxiliary reflection film body is pressed by the LED lamp, the deformation degree of the auxiliary reflection film body is greatly reduced due to the existence of the reinforcing layer, so that the backlight of the mobile phone is more uniform.
In addition, a plurality of elongated reinforcing strips may be provided on the surface of the sub-reflecting film body. When the auxiliary reflecting film body is pressed by the LED lamp, the deformation degree of the auxiliary reflecting film body is greatly reduced due to the existence of the reinforcing strip, so that the backlight of the mobile phone is more uniform. In addition, because gaps exist between the reinforcing strips, the light transmittance of the auxiliary reflecting film body can be improved, and therefore the backlight of the mobile phone is more uniform.
In addition, a plurality of round supporting protruding points can be arranged on the surface of the auxiliary reflecting film body. When the auxiliary reflecting film body is pressed by the LED lamp, the deformation degree of the auxiliary reflecting film body is greatly reduced due to the existence of the supporting convex points, so that the backlight of the mobile phone is more uniform. In addition, because gaps exist between the supporting convex points, the light transmittance of the auxiliary reflecting film body can be improved, and therefore the backlight of the mobile phone is more uniform.

As described in the background art, in the prior art, for the existing backlight structure of mobile phones, in order to improve brightness, the reflective film may extend into the bottom of the LED lamp. However, because there is a certain tolerance in each fitting, the gap between the LED lamp and the reflective film is too small, and after assembly, the LED lamp may press against the reflective film, resulting in the problem of wrinkling of the reflective sheet during reliability experiments.
In order to solve the technical problem, the utility model provides a split type LED reflective film assembly 1, which comprises a main reflective film body 2, wherein a plurality of auxiliary reflective film bodies 3 are arranged at the bottom edge of the main reflective film body 2, a preset first interval M1 is arranged between the adjacent auxiliary reflective film bodies 3, and a preset second interval M2 is arranged between the top edge of the auxiliary reflective film body 3 and the bottom edge of the main reflective film body 2.
Through the structural design, as the whole reflecting film adopts a separation structure, even if the auxiliary reflecting film body 3 is pressed by the LED lamp, the pressure can not be transmitted to the main reflecting film body 2, thereby completely avoiding the occurrence of the wrinkling of the reflecting film and improving the reliability of the backlight structure of the mobile phone.

The operation of this embodiment will be described below.
When the secondary reflection film body 3 is pressed by the LED lamp, the deformation degree of the secondary reflection film body 3 is greatly reduced due to the existence of the supporting convex points 33, so that the backlight of the mobile phone is more uniform. In addition, since the gaps exist between the supporting protrusions 33, the light transmittance of the sub-reflecting film body 3 can be improved, thereby making the backlight of the mobile phone more uniform.
