The stress of each point in display panel, and then reduce the phase changing capacity through the light of display panel outgoing, solve existing song
The serious phenomenon of light leak at lower four angles of flat-panel display device dark-state pattern, the uniformity of display panel problem not high, realizes
The light leak of display panel is reduced or eliminated, the uniformity effects of display panel are improved.
The structural representation of another display device that Fig. 6 is provided for the embodiment of the present application.With Fig. 4 a and Fig. 4 b offers
Display device is compared, and second includes that body and the multiple being formed on body are raised in the display device provided in Fig. 6.Tool
Body ground, referring to Fig. 6, this second 32 includes body and the multiple raised 324 being formed on body 323.Body 323 is thickness
Uniform laminated structure.Multiple raised 324 are spaced setpoint distance is arranged on second 32 body 323, in the middle of second 32
Second 32 end 322 direction is pointed in position 321, and raised 324 thickness and/or hardness are gradually reduced.
Exemplarily, referring to Fig. 6, alternatively, raised 324 material is hard material, by second 32 centre position 321
The thickness for pointing to second direction projection 324 of 32 end 322 is gradually reduced.Second thickness in 32 centre positions 321 is m, the
Two thickness of 32 ends 322 are n (m is more than n), and second end 322 direction is pointed to along second 32 centre position 321, the
The thickness of two 32 is reduced to n by m.
Alternatively, the material that can also set raised the 324 of second 32 is the different material of hardness, centre position 321
The hardness of the hardness more than projection 324 at end 322 at place raised 324.For example, projection 324 at second 32 centre position 321
Material is PET, and the material of projection 324 is bubble silk floss at second 32 end 322.On this basis, can be with
The original depth that setting points to second direction projection 324 of 32 end 322 by second 32 centre position 321 is gradually reduced；Such as
Shown in Fig. 7, it is also possible to which the original depth for setting second 32 various location projection 324 is identical.
If the original depth of second 32 various location projection 324 is identical, support frame 30 is being arranged at curved-surface display
When between panel 10 and curved surface backlight module 20, because 30 first 31 and second 32 are connected (i.e. second with support frame
32 ends 322) place's display device stress is larger, and raised the 324 of continuous material will be steeped at second 32 end 322 and will be compressed, to cause
Can be fitted with curved face display panel and curved surface backlight module well for second 32, to reduce answering for display device position
Power.
The embodiment of the present application points to second end direction by setting second centre position of support frame, and support frame is raised
Thickness and/or hardness be gradually reduced, the stress of each point in curved face display panel can be effectively reduced, and then reduce through display surface
The phase changing capacity of the light of plate outgoing, solves light leak at lower four angles of existing curved-surface display device dark-state pattern serious
Phenomenon, the uniformity of display device problem not high, realizes the light leak for reducing or eliminating display device, improves display device
Uniformity effects.
