Detailed Description
The invention is described in further detail below with reference to the figures and the specific examples, but the invention is not limited thereto.
Referring to fig. 1 to 3, the embodiment of the invention provides a display device, which includes a circuit board 1 on which a display is mounted, a light-shielding member 2, a cover plate 5 and a photosensitive element, wherein the photosensitive element and the light-shielding member 2 are mounted on the circuit board 1, the light-shielding member 2 has a circumferential opening 4, the light-shielding member 2 is disposed around the circumference of the photosensitive element, the circumferential opening 4 faces to a side far away from the display on the circuit board 1, and the cover plate 5 covers an end of the light-shielding member 2 far away from the circuit board 1. Preferably, the shade 2 is U-shaped.
Because the light shielding part 2 shields the light path between the photosensitive element and the display, the light emitted by the display can be prevented from irradiating the photosensitive element, so that the photosensitive element can effectively work. In addition, because the lower end of the light shielding member 2 is directly mounted on the circuit board 1, and the upper end is abutted against the cover plate 5, a sealing structure for sealing light can be formed at the contact part between the light shielding member 2 and the circuit board 1 and between the light shielding member 2 and the cover plate 5, and light can be prevented from penetrating into the area enclosed by the light shielding member 2 from the two contact parts, so that the interference problem of the display area of the display to the photosensitive element can be improved and avoided.
Because the shading member 2 of the invention is provided with the circumferential opening 4, when the cover plate 5, the shading member 2 and the circuit board 1 are assembled, an extrusion force is applied to the shading member 2, and at the moment, the extrusion force can be released through the circumferential opening 4, thereby not only avoiding the problem that the cover plate bulges upwards when the extrusion force cannot be released, but also leading the shading member to be more effectively contacted with the circuit board and the cover plate and improving the shading effect. In addition, still can be through the peripheral opening 4 with the light shield 2 extrusion deformation in-process, the gas in the space that light shield 2 encloses is discharged through peripheral opening 4, therefore also can avoid adopting the light shield of annular structure all around among the prior art, and the atmospheric pressure of the inside air of light shield leads to the problem that the apron is bloated.
The light blocking member 2 may be connected to the circuit board 1 in various ways. For example, the light shielding member 2 is detachably connected to the circuit board 1 by means of, for example, a snap structure or the like; the light shading part 2 and the circuit board 1 can also be connected by means of pins, or by means of adhesion, or by means of threads.
When the snap structure is adopted, preferably, the snap structure comprises a clamping arm 8 connected with the shading piece 2 and a clamping groove 9 positioned on the circuit board 1, and the clamping arm 8 is clamped with the clamping groove 9. During installation, the clamping arm 8 can be clamped into the clamping groove 9, so that the light shielding part 2 is detachably connected with the circuit board 1. Like this, to the display device of isostructure, as long as its buckle structure's draw-in groove can cooperate with the card arm, can realize the installation of light-shielding piece, therefore improved the adaptability and the commonality of light-shielding piece 2 installation. Due to the adoption of the structure, corresponding photosensitive elements can be added in different display devices.
Preferably, the light-shielding member 2 is made of an elastic material, so that a sealing shielding effect against light can be more effectively achieved when pressed by the cover plate 5 and the circuit board 1.
Referring to fig. 4 to 7, preferably, one end of the light shielding member 2 facing the cover plate 5 is formed as a flared structure 6, which is gradually enlarged toward the cover plate to receive more external light.
In order to improve the light shielding effect, the invention can also form a circle of light shielding rabbets 7 protruding outwards at the end part of the light shielding piece 2 facing one end of the circuit board 1. The light shielding seam allowance 7 can increase the contact surface of the light shielding member 2 and the circuit board 1, thereby increasing the sealing effect and more effectively blocking the interference of the display light to the photosensitive element. In addition, a light shielding rib 3 protruding and extending to the outer side of the light shielding member 2 may be formed at the free end of the circumferential opening 4 of the light shielding member 2, so that the photosensitive element can be more effectively kept away from the interference of the display.
Preferably, the display device further includes a mounting bracket 10, the circuit board 1 is mounted on one side of the mounting bracket 10, and the cover plate 5 is mounted on the other side of the mounting bracket 10. After the installation, the cover plate 5, the mounting frame 10 and the circuit board 1 are combined into a structure similar to a box, and the shading member 2 is positioned inside the structure.
