[embodiment]
The profile of the utility model S shape LED display embodiment 1-3 is as shown in Figure 1, comprises lamp bar 1 and the flexible joint plate 2 that is connected lamp bar 1, and the lamp bar comprises substrate 101 and LED light-emitting component 102, and flexible joint plate 2 is fixed on the back side of lamp bar 1.
As shown in Figure 2, among the utility model S shape LED display embodiment 1 between two lamp bars 1 connecting portion 201 of flexible joint plate 2 be U-shaped, the bottom of U-shaped connecting portion 201 is towards the place ahead of lamp bar 1, opening is towards the rear of lamp bar 1.When S shape LED display was crooked, the flexural center Oa of flexible joint plate 2 was between the end face of the back side of lamp bar 1 and lamp bar 1.
Under straightened condition, the distance on two adjacent lamps bars between the LED light-emitting component 102 is S; When the downwarping of S shape LED display, the distance on two adjacent lamps bars between the LED light-emitting component 102 is S1a; When S shape LED display was bent upwards, the distance on two adjacent lamps bars between the LED light-emitting component 102 was S2a.
As shown in Figure 5, when prior art S shape LED display was crooked, the flexural center O of flexible joint plate 2 was positioned at the centre of the connecting portion 201 of flexible joint plate 2.Prior art S shape LED display is under straightened condition, and the distance on two adjacent lamps bars between the LED light-emitting component 102 is S; When the downwarping of S shape LED display, the distance on two adjacent lamps bars between the LED light-emitting component 102 is S1; When S shape LED display was bent upwards, the distance on two adjacent lamps bars between the LED light-emitting component 102 was S2.
Comparison diagram 2 can find out with Fig. 5, when S shape LED display is crooked, because the position of Oa and O is different, and S1＞S1a＞S, S2＜S2a＜S; That is to say that when S shape LED display was crooked, embodiment 1 reduced the distance that light-emitting component is drawn close or separated, and has reduced between the display screen flexural deformation back light bar abnormal show situations such as bright band or black-tape to occur, improves the quality of LED display.
As shown in Figure 3, what the utility model S shape LED display embodiment 2 and embodiment 1 were different is, the web joint 201 between the lamp bar is a V-arrangement, and V-arrangement web joint 201 is connected through rivet 202 (or screw) by left and right two parts.The bottom of V-arrangement web joint 201 is positioned on the line of adjacent light-emitting component 102 end faces, and the flexural center Ob of flexible joint plate 2 is positioned at rivet 202 positions.
Comparison diagram 3 can find out with Fig. 2, when S shape LED display is crooked, because the position of Ob and Oa is different, and more near the end face of adjacent light-emitting component 102, S1a＞S1b ≈ S, S2a＜S2b ≈ S; That is to say; When S shape LED display is crooked; Embodiment 2 further reduces the distance that light-emitting component is drawn close or separated, and has avoided abnormal show situations such as bright band or black-tape occurring between the display screen flexural deformation back light bar, has further improved the quality of LED display.
As shown in Figure 4; What the utility model S shape LED display embodiment 3 and embodiment 2 were different is; Web joint 201 between the lamp bar is a U-shaped; The bottom of U-shaped web joint 201 is positioned on the line of adjacent light-emitting component 102 end faces, because U-shaped web joint 201 is very thin, the flexural center Oc of flexible joint plate 2 is just on the line of adjacent light-emitting component 102 end faces.
Because the flexural center Oc of flexible joint plate 2 is just on the line of adjacent light-emitting component 102 end faces; When S shape LED display is crooked; S1c=S2c=S; Distance between the adjacent light-emitting component 102 can not change, and has avoided drawing close or dividing because of light-emitting component the defective of the abnormal show such as occurring bright band or black-tape between the bar of turning on light fully, has guaranteed the quality of LED display.
