The display effect of the curved display module 200 is normal. Thus, the display defect of the curved display module 200 caused by the separation of the lamp panel 213 and the bezel 211 due to the bending stress is avoided.
FIG. 3 is a schematic side view of another curved-surface display module according to an embodiment of the invention.
As shown in fig. 3, the hook 212 further includes a third hook portion 212C; the third hook portion 212C is located on one side of the lamp panel 213 close to the bezel back panel 211A, the third hook portion 212C is fixed with the first hook portion 212A, and the third hook portion 212C is fixed with the bezel back panel 211A.
In the embodiment of the present invention, in the hooks 212, the third hook portion 212C is located on the side of the lamp panel 213 close to the bezel back panel 211A, the third hook portion 212C is fixed to the first hook portion 212A, and the third hook portion 212C is fixed to the bezel back panel 211A. The hook 212 and the bezel 211 are not separated by bending stress. The first hook portion 212A, the second hook portion 212B and the third hook portion 212C play a role in limiting together with the iron frame 211. The lamp panel 213 is clamped by the first, second, and third hook portions 212A, 212B, 212C and the bezel 211. The lamp panel 213 is not separated from the bezel 211 by the bending stress. The relative positions of the lamp panel 213 and the light source 214 and the bezel 211 are unchanged. The effect of the backlight light emitted by the curved backlight module 210 is normal. The relative position of the light source 214 and the curved liquid crystal panel 220 is unchanged. The backlight light emitted from the curved backlight module 210 is emitted through the curved liquid crystal panel 220 with a normal effect. The display effect of the curved display module 200 is normal. Thus, the display defect of the curved display module 200 caused by the separation of the lamp panel 213 and the bezel 211 due to the bending stress is avoided.
As shown in fig. 2 and 3, the distance between the second hook 212B and the lamp panel 213 is less than or equal to 0.05 mm.
In an embodiment of the invention, on the one hand, there is a space between the second hook portion 212B and the lamp panel 213. An error is allowed between the second hook portion 212B and the lamp panel 213. It is easy to form the hook 212 by passing the first hook 212A through the panel opening hole 213A and exposing the second hook 212B on the side of the panel 213 away from the bezel back 211A. On the other hand, the distance between the second hook portion 212B and the lamp panel 213 is less than or equal to 0.05 mm, preferably equal to 0.05 mm. The moving space of the lamp panel 213 between the second hook 212B and the bezel back 211A is very small. The hook 212 and the iron frame 211 have good limiting effect on the lamp panel 213. The hook 212 and the bezel 211 completely lock the lamp panel 213. Thus, the display defect of the curved display module 200 caused by the separation of the lamp panel 213 and the bezel 211 due to the bending stress is avoided.
As shown in fig. 2 and 3, the second hook portion 212B is substantially perpendicular to the extending direction of the first hook portion 212A, and the first hook portion 212A is substantially perpendicular to the bezel back plate 211A.
In the embodiment of the invention, the first hook portion 212A is substantially perpendicular to the bezel back 211A, so that the first hook portion 212A penetrates through the lamp panel opening hole 213A. The second hook portion 212B is substantially perpendicular to the extending direction of the first hook portion 212A, so that the second hook portion 212B is exposed at a side of the lamp panel 213 away from the bezel back panel 211A. The bending stress causes the lamp panel 213 to move toward the side away from the bezel back plate 211A, and the first and second hook portions 212A and 212B block the lamp panel 213 from separating from the bezel 211. The hook 212 and the bezel 211 lock the lamp panel 213. The relative positions of the lamp panel 213 and the light source 214 and the bezel 211 are unchanged. The effect of the backlight light emitted by the curved backlight module 210 is normal. The relative position of the light source 214 and the curved liquid crystal panel 220 is unchanged. The backlight light emitted from the curved backlight module 210 is emitted through the curved liquid crystal panel 220 with a normal effect. The display effect of the curved display module 200 is normal. Thus, the display defect of the curved display module 200 caused by the separation of the lamp panel 213 and the bezel 211 due to the bending stress is avoided.
As shown in fig. 2 and 3, the iron frame 211 and the hook 212 are integrally formed.
In the embodiment of the present invention, the bezel 211 and the hook 212 are integrally formed. The iron frame 211 and the hook 212 are originally made of one piece of original material. Here, the bezel 211 and the hook 212 are formed by using a single piece of original material. The integrally formed hook 212 is directly fixed to the bezel back plate 211A. This avoids the use of other materials or other components to secure the hook 212 to the bezel back plate 211A. The integrally formed iron frame 211 and the hook 212 have a good limiting effect. The integrated hook 212 and the iron frame 211 completely block the lamp panel 213. Thus, the display defect of the curved display module 200 caused by the separation of the lamp panel 213 and the bezel 211 due to the bending stress is avoided.
As shown in fig. 2 and 3, the first hook portion 212A and the second hook portion 212B are integrally formed.
In the present embodiment, the first hook portion 212A and the second hook portion 212B are integrally formed. The first hook portion 212A and the second hook portion 212B originally belong to one piece of original material. Here, the first and second hook portions 212A and 212B are formed using one piece of raw material, respectively. The integrally formed first hook portion 212A and the second hook portion 212B are directly fixed. This avoids the use of other materials or other components to secure the second hook portion 212B to the first hook portion 212A. The bending stress causes the lamp panel 213 to move toward the side away from the bezel back plate 211A, and the integrally formed first and second hook portions 212A and 212B completely block the lamp panel 213 from separating from the bezel 211. The hook 212 completely blocks the lamp panel 213 through the integrally formed first hook portion 212A and second hook portion 212B and the bezel 211. Thus, the display defect of the curved display module 200 caused by the separation of the lamp panel 213 and the bezel 211 due to the bending stress is avoided.
FIG. 4 is a schematic side view of another curved-surface display module according to an embodiment of the invention.
As shown in fig. 4, the bezel 211 includes a bezel opening 211B; the bezel opening 211B is punched in the bezel 211, and the hook 212 is bent at the bezel opening 211B.
In the embodiment of the present invention, the bezel opening 211B is punched on the bezel 211, so that the material originally located in the bezel opening 211B is used as the hook 212. The hooks 212 are formed by bending at the bezel openings 211B to form a first hook portion 212A and a second hook portion 212B. Then, the first hook portion 212A penetrates the lamp panel opening hole 213A, and the second hook portion 212B is exposed at a side of the lamp panel 213 away from the bezel back panel 211A. The bending stress causes the lamp panel 213 to move toward the side away from the bezel back plate 211A, and the first and second hook portions 212A and 212B block the lamp panel 213 from separating from the bezel 211. The hook 212 and the bezel 211 lock the lamp panel 213. Thus, the display defect of the curved display module 200 caused by the separation of the lamp panel 213 and the bezel 211 due to the bending stress is avoided.
As shown in fig. 2 and 3, the hook 212 and the lamp panel opening 213A are located between two adjacent light sources 214.
In the embodiment of the invention, the hook 212 and the lamp panel opening 213A are located between two adjacent light sources 214. The hook 212 does not block any light source 214 from emitting light. The light panel apertures 213A do not affect the setting of the light sources 214. The light emitted from the light source 214 forms the backlight light of the curved backlight module 210. The curved-surface display module 200 utilizes the backlight light emitted from the curved-surface backlight module 210 to emit through the curved-surface liquid crystal panel 220 to display an image. The hook 212 and the bezel 211 lock the lamp panel 213. Thus, the display defect of the curved display module 200 caused by the separation of the lamp panel 213 and the bezel 211 due to the bending stress is avoided.
FIG. 5 is a schematic top view of another curved display module according to an embodiment of the invention.
As shown in fig. 5, the distribution density of the hooks 212 at the center of the lamp panel 213 is greater than the distribution density of the hooks 212 at the edge of the lamp panel 213.
In the embodiment of the present invention, the bending stress of the center of the lamp panel 213 is greater than that of the edge of the lamp panel 213. The distribution density of the hooks 212 at the center of the lamp panel 213 is greater than the distribution density of the hooks 212 at the edge of the lamp panel 213. The limiting acting force of the hook 212 and the iron frame 211 to the center of the lamp panel 213 is greater than the limiting acting force of the hook 212 and the iron frame 211 to the edge of the lamp panel 213. The larger limiting force of the hooks 212 and the iron frame 211 to the center of the lamp panel 213 offsets the larger bending stress of the center of the lamp panel 213. The small limiting force of the hooks 212 and the iron frame 211 on the edge of the lamp panel 213 offsets the small bending stress of the edge of the lamp panel 213. Thus, the display defect of the curved display module 200 caused by the separation of the center of the lamp panel 213 from the bezel 211 due to the bending stress is avoided. Meanwhile, the display defect of the curved display module 200 caused by the separation of the edge of the lamp panel 213 from the bezel 211 due to the bending stress is avoided.
As shown in fig. 5, the distribution density of the hooks 212 gradually decreases from the center of the lamp panel 213 to the edge of the lamp panel 213.
In the embodiment of the present invention, the bending stress is gradually reduced from the center of the lamp panel 213 to the edge of the lamp panel 213. The distribution density of the hooks 212 gradually decreases from the center of the lamp panel 213 to the edge of the lamp panel 213. The limiting acting force of the hook 212 and the iron frame 211 on the lamp panel 213 is gradually reduced from the center of the lamp panel 213 to the edge of the lamp panel 213. At any position of the lamp panel 213, the limiting force of the hook 212 and the bezel 211 to the position of the lamp panel 213 counteracts the bending stress of the position of the lamp panel 213. Therefore, the display defect of the curved display module 200 caused by the separation of any position of the lamp panel 213 from the bezel 211 due to the bending stress is avoided.
FIG. 6 is a schematic side view of another curved-surface display module according to an embodiment of the invention.
As shown in fig. 6, the curved backlight module 210 further includes a reflector 215; the reflector plate 215 is located on the side of the lamp panel 213 away from the bezel back plate 211A and covers the hook 212.
In the embodiment of the present invention, the reflector 215 is located on a side of the lamp panel 213 away from the bezel back plate 211A and covers the hook 212. In the curved backlight module 210, the light source 214 emits a first light toward a side away from the bezel back plate 211A. Meanwhile, the light source 214 emits a second light toward the side close to the bezel back plate 211A, and the reflective sheet 215 reflects the second light emitted from the light source 214 toward the side far from the bezel back plate 211A. Thus, the first light and the second light constitute the backlight light of the curved backlight module 210. The curved-surface display module 200 utilizes the backlight light of the curved-surface backlight module 210 to emit through the curved-surface liquid crystal panel 220 to display images. In addition, the hook 212 is made of a metal material with high light reflection rate, such as iron. The hooks 212 reflect light toward the side away from the bezel back plate 211A. The light reflected by the hook 212 interferes with the image of the curved display module 200. The reflective sheet 215 blocks light from irradiating the hook 212 and reflects on the hook 212. This prevents the light reflected by the hook 212 from interfering with the image of the curved display module 200.
As shown in fig. 2 and 3, the curved display module 200 further includes a curved liquid crystal panel 220; the ratio of the pitch of the two adjacent light sources 214 to the curved liquid crystal panel 220 is greater than 99% and less than 101%.
In the embodiment of the present invention, the lamp panel 213 is fastened by the hooks 212 and the bezel 211. The lamp panel 213 is not separated from the bezel 211 by the bending stress. The relative positions of the lamp panel 213 and the light source 214 and the bezel 211 are unchanged. The relative position of the light source 214 and the curved liquid crystal panel 220 is unchanged. The ratio of the pitch of the two adjacent light sources 214 to the curved liquid crystal panel 220 is greater than 99% and less than 101%. The backlight light emitted from the curved backlight module 210 is emitted through the curved liquid crystal panel 220 with a normal effect. The display effect of the curved display module 200 is normal. Thus, the display defect of the curved display module 200 caused by the separation of the lamp panel 213 and the bezel 211 due to the bending stress is avoided.
