Of course, the light source assembly may further include a member for controlling the switching of the light source, and the like. Preferably, the light source is an LED light source.
In addition, the display device in the above technical solution provided by the present invention may further have the following additional technical features:
in the above technical scheme, a light hole is formed in the light shielding member, and the light hole defines the light transmission part.
Because the shading piece has the shading function, light cannot pass through, the light can pass through the shading piece to be projected onto the display panel by arranging the light holes on the shading piece, and the display part on the display panel is matched with the shape of the light transmission part, so that the shape defined by the light holes is also the shape of the display part; the light-transmitting part is limited by the light-transmitting hole, so that the shielding of the light-transmitting part on light rays can be reduced as much as possible, and the light rays can penetrate through the light-transmitting part as much as possible, thereby being beneficial to improving the display brightness of the display device; meanwhile, the structure is simple, and the processing and forming are easy.
In the above technical solution, one side of the light shielding member facing the display panel is further provided with a light shielding rib extending along an edge of the light transmitting hole.
The side, facing the display panel, of the light shading piece is also provided with light shading ribs, and the light shading ribs extend along the edges of the light holes, so that the light shading ribs can limit the light rays passing through the light holes to diffuse to other parts, the projected light edges are relatively neat, and the phenomenon of light crosstalk and halation is avoided as much as possible; meanwhile, the shading ribs can also play a role of reinforcing ribs, and the strength of the shading piece is improved.
In the above technical scheme, the number of light trap is a plurality of, and is a plurality of light trap interval arrangement, wherein, at least adjacently be equipped with between the light trap the shading rib.
The number of the light holes is multiple, and the light holes are arranged at intervals and can form various shapes, so that the display requirement of the display device is met; wherein, because the distance between the adjacent light trap is relatively nearer, the phenomenon of crosstalk takes place more easily, therefore at least sets up the shading rib (being equivalent to the both sides of a shading rib extend along the edge of two adjacent light traps respectively) between adjacent light trap to avoid taking place the phenomenon of crosstalk halo between the adjacent light trap as far as possible, and then improve display device's display effect.
In the above technical solution, the light-transmitting portion includes a first sub light-transmitting portion, the first sub light-transmitting portion includes seven light-transmitting holes, and the seven light-transmitting holes are all strip-shaped and arranged at intervals in the transverse and longitudinal directions, so that the first sub light-transmitting portion is in a shape of 8; wherein, violently indulge adjacent two all be equipped with between the light trap shading rib.
The light transmission part comprises a first sub light transmission part which is formed by enclosing seven strip-shaped light transmission holes into an 8 shape, and the display part is matched with the light transmission part in shape, so that the display part also comprises a display structure in the 8 shape to form a common seven-segment digital display structure. Specifically, the first sub light transmission part is composed of three transversely extending strip-shaped light transmission holes and four longitudinally extending strip-shaped light transmission holes, the three transversely extending strip-shaped light transmission holes are arranged in parallel from top to bottom, and the four longitudinally extending strip-shaped light transmission holes are arranged between the adjacent transverse light transmission holes in parallel. Therefore, compared with the distance between two adjacent transverse light-transmitting holes and the distance between two adjacent longitudinal light-transmitting holes, the distance between two transverse and longitudinal adjacent light-transmitting holes is relatively close, and particularly crosstalk is more likely to occur at two adjacent ends, so that the shading ribs are arranged at least between two transverse and longitudinal adjacent light-transmitting holes to obviously weaken the crosstalk halo phenomenon; and because the first sub light-transmitting part comprises an upper square-shaped part and a lower square-shaped part, and the four corners of the square-shaped part are all required to be provided with the shading ribs, the number of the shading ribs is at least 8.
In the technical scheme, a gap between two light holes which are adjacent in the transverse and longitudinal directions is rectangular, and the gap is obliquely arranged relative to the light holes; the length of the shading rib is larger than that of the gap, so that one end of the shading rib protrudes out of the first sub light-transmitting part.
The gaps between the two transversely and longitudinally adjacent light holes are rectangular, and are obliquely arranged relative to the light holes, so that the strip-shaped light holes positioned on the outer periphery are integrally isosceles trapezoid, the transverse light holes positioned in the middle are correspondingly symmetrical hexagons, and the opposite edges of the two transversely and longitudinally adjacent light holes are parallel to each other, so that the distance between the transversely and longitudinally adjacent light holes can be reduced as much as possible, the whole 8-shaped figure looks more coherent and compact, and the display effect is better; correspondingly, the shading ribs between two light holes which are adjacent transversely and longitudinally are also obliquely arranged. Preferably, the gap is inclined at an angle of 45 °.
Further, the length of shading rib is greater than the length in clearance, makes the one end protrusion in first sub-light-transmitting portion of shading rib, can guarantee like this that light can not pass the clearance between the horizontal and vertical adjacent light trap to the shading effect of shading rib has further been promoted.
In the above technical scheme, the portions of the two longitudinally adjacent shading ribs in the middle part protruding from the first sub light transmission part are combined into a whole, so that the two shading ribs form a Y-shaped structure.
Two longitudinally adjacent shading ribs located in the middle, namely: two shading ribs between two vertical light trap and the middle horizontal light trap of upper and lower adjacent, because the slope opposite direction of these two shading ribs, therefore the two protrusion is close to each other in the one end of first sub-printing opacity portion, so unite two into one and the level extension with the part of the two protrusion in first sub-printing opacity portion, make these two shading ribs form Y shape structure, both avoided two protrusion mutual interference, make overall structure symmetry balanced again, and the machine-shaping of being convenient for.
