Embodiment
Embodiment 1: as shown in Fig. 6 or Fig. 7, and a kind of straight-down negative curved surface display device, it comprises arc backlight module and is located at the display panel 6 of arc backlight module top; Described arc backlight module comprises arc storing apparatus 3, light source 2 and is stacked in successively reflector plate 1, diffuser plate 4 and the optical diaphragm group 5 in arc storing apparatus 3; Four sides of described reflector plate 1 are respectively equipped with flanging, and reflector plate 1 all at least has the broken line 15,16 in a place on two flangings 11,12 of bending direction; Described reflector plate 1 disconnects at broken line 15,16 places completely at two flangings 11,12 of bending direction.
Described reflector plate 1 is all at least provided with place's mark line 18,17 on two flangings 11,12 of bending direction, and described mark line 11,12 has one end to be connected with broken line 18,17 respectively.
Light source 2 is directly-down light source, and this light source 2 is located between diffuser plate 4 and reflector plate 1.
As shown in Fig. 6 or Fig. 7, the bending direction of curved surface display device is the long side direction of reflector plate 1, so reflector plate 1 bending, on long limit, material extrusion can occur, produces projection and out-of-flatness.On two flangings 11,12 on reflection length of a film limit, do brokenly respectively line 15, broken line 16, after reflector plate 1 bends, the material extrusion on long limit discharges in broken line 15,16 positions.
As shown in Figure 8, enlarged drawing for reflector plate 1 broken line 16 parts on flanging 11, broken line 16 can be used the cutting die of reflector plate directly to cut, and long and narrow thin-line-shaped, the otch that two ends connect that form, the roulette that mark line 17 is the discontinuous cut that adopts reflector plate cutting die and form.
As shown in Figure 9, left part 121 and the right side part 122 of reflection length of a film limit after broken line place 16 separates completely, the broken line corresponding broken line of 16 left part 121 limits 161, the broken line 16 right side part broken line of 122 correspondence limits 162.When reflector plate is assembled on backboard, on broken line limit, 161,162 places discharge the material extrusion part that reflector plate buckling causes, the mark line of 161Jiang Yu right side, the broken line limit part 122 of left part 121 is overlapping, specifically as shown in figure 10.The principle of broken line 15 is identical with the principle of broken line 16.
As shown in Fig. 8 or Fig. 9, because the material of part reflector plate is thinner, during reflector plate assembling, be easily out of shape, now can the part between broken line 16 and mark line 17 increase double faced adhesive tape, during reflector plate assembling, can by double faced adhesive tape and mark line 17, fit breaking line limit 161, to prevent distortion.
Embodiment 2: during reflector plate buckling the number of material extrusion with the size of display panel, the radius-of-curvature of display device and mixed light height etc. are relevant.The material extrusion part needing when radius-of-curvature is less and mixed light height is larger can be more, now just need many places to break line, to guarantee the flatness on the reflection length of a film limit of curved surface display device.
As shown in figure 11, at the bending direction of curved surface display device, be long limit, on two flangings 11,12 on the long side direction of reflector plate 1, line processing is done broken in equal two positions, to discharge the situation of more material extrusion.
Embodiment 3: in order to improve the colour gamut of curved surface display device, can use blue light source to add the scheme of red green quanta point material.As shown in Figure 6, light source 2 is blue-ray LED, has at least parts to contain ruddiness and green light quantum point material in reflector plate 1, diffuser plate 4 and optical diaphragm group 5.When the blue light process ruddiness that blue-ray LED sends and green light quantum point material, inspire ruddiness and green glow, the blue light of light source 2 and ruddiness and green glow are mixed into white light, thereby improve the colour gamut of curved surface display device.
Simple for making, also can be using quanta point material separately as an individual components, arc backlight module also comprises quantum dot parts, these quantum dot parts can be above diffuser plate 4, below diffuser plate 4, between optical diaphragm group 5 or above optical diaphragm group 5.Quantum dot parts contain ruddiness and green light quantum point, and the blue light that blue-ray LED sends inspires ruddiness and green glow while passing through quantum dot parts, and the blue light of light source 2 and ruddiness and green glow are mixed into white light.Quantum dot parts also can improve the colour gamut of curved surface display device, and make simple.
Embodiment 4: use quantum dot can increase substantially the colour gamut of display frame very much, but price is higher.Therefore the mode that can use blue chip to add red green fluorescence powder improves the colour gamut of display frame.
As shown in Figure 6, light source 2 is blue chip and the white light LEDs of red green fluorescence powder composition or the white light LEDs being comprised of blue chip, green glow chip and red light fluorescent powder, and this light source 2 can improve colour gamut equally, and cost is relatively low.
