[0049] In order to make the above-mentioned purposes, features and advantages of the present disclosure more obvious and understandable, the technical solutions in the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings in the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, rather than all the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

[0050] In the related art, refer to Figure 1 , Figure 1 The structure diagram of the rubber frame assembly in the related art is shown as follows: Figure 1As shown, a foam 11ˊ is provided in the vehicle-mounted display module. By setting the foam 11ˊ in the rubber frame 1ˊ, the impact force on the display panel can be reduced. However, the movement of the vehicle may cause the foam 11ˊ to escape from the rubber frame 1ˊ. In this case, the position of the foam 11ˊ can be limited by setting a retaining wall in the rubber frame 1ˊ. Among them, the foam 11ˊ in the rubber frame 1ˊ carries the display panel, and the retaining wall can limit the foam 11ˊ to prevent it from jumping out of the rubber frame 1ˊ. However, due to the existence of the retaining wall, the light emitted from the optical film material of the backlight module will be reflected by the retaining wall to the display area of ​​the display panel, which results in more light emitted from the edge of the display area, resulting in a short bright line at the edge of the display area, affecting the user's viewing experience.

[0051] In view of this, the present disclosure proposes a plastic frame assembly and a display device, which retracts the baffle wall of the plastic frame assembly so that light incident on the baffle wall area can be reflected to areas other than the display area of ​​the display panel, thereby eliminating the short bright lines in the corner area of ​​the display panel and improving the user's viewing experience.

[0052] Reference Figure 2 , Figure 3 as well as Figure 6 , Figure 2 The structure diagram of the plastic frame assembly provided by the embodiment of the present disclosure is shown. Figure 3 Shows Figure 2 A magnified image of area A. Figure 6 Shows Figure 3 The cross-section of the middle rubber frame assembly is as follows: Figure 2 , Figure 3 as well as Figure 6 As shown, the rubber frame assembly specifically includes:

[0053] The plastic frame 11 is a frame-shaped structure, and each frame of the plastic frame 11 includes a first portion 111 and a second portion 112 connected in an L shape, and the first portion 111 has a first side wall 1111 away from the second portion 112; and

[0054] A retaining wall 12 connected to the first portion 111 and disposed opposite to the second portion 112, the retaining wall 12 having a second side wall 121 away from the second portion 112;

[0055] The first distance between the first sidewall 1111 and the second portion 112 is greater than the second distance between the entire or partial sidewall section of the second sidewall 121 and the second portion 112 .

[0056] Specifically, the plastic frame 11 is a frame-type structure, which can fix the display panel, wherein the first part 111 of the L-shaped connection in each frame can carry the display panel, and the second part 112 can limit the display panel within the frame-type structure.

[0057] It is understandable that a bearing member for bearing the display panel is usually disposed in the plastic frame 11. The bearing member is usually located in the first portion 111, that is, the display panel is carried on the back of the display panel. The bearing member is usually made of elastic material and can play a buffering role when the display panel is subjected to external forces such as impact to prevent damage to the display panel. In order to prevent the bearing member from falling off to the display area of ​​the display panel, a retaining wall 12 is provided to limit the position of the bearing member.

[0058] Among them, the retaining wall 12 can be located in the connecting area of ​​the two frames of the plastic frame 11, that is, the four corner areas of the frame structure. The retaining wall 12 is set at the four corners of the plastic frame 11 to prevent the bearing component from falling off. Of course, the retaining wall 12 can also be located in the four frames of the plastic frame 11, so that the bearing component can be completely confined between the retaining wall 12 and the second part 112.

[0059] In this embodiment, continue to refer to Figure 3 and Figure 6 The first distance between the first side wall 1111 and the second portion 112 can represent the width of the first portion 111, and the second distance between the second side wall 121 and the second portion 112 can represent the spacing between the side of the retaining wall 12 away from the second portion 112 and the second portion 112. The difference between the first distance and the second distance can represent the distance between the first side wall 1111 and the second side wall 121; wherein the first distance is greater than the second distance, representing that the second side wall 121 is retracted relative to the first side wall 1111, so that the incident light can be prevented from being reflected by the retaining wall 12 to the display area of ​​the display panel, thereby eliminating the short bright lines at the edge of the display area.

[0060] In this embodiment, the second side wall 121 can be completely retracted relative to the first side wall 1111, or can be partially retracted relative to the first side wall 1111; wherein, when the second side wall 121 is completely retracted relative to the first side wall 1111, the first distance between the first side wall 1111 and the second portion 112 is greater than the second distance between the entire side wall section of the second side wall 121 and the second portion 112, so that Figure 3 and Figure 6 For example, all side wall segments refer to all side wall segments of the second side wall 121 in the z direction. In this case, the second side wall 121 can be retracted by a certain dimension relative to the first side wall 1111 so that the light at a 45-degree angle does not enter the second side wall 121, or the shape of the second side wall 121 can be adjusted while retracting so that the light entering the second side wall 121 at a 45-degree angle can be reflected outside the display area.

[0061] The second side wall 121 may also be partially retracted relative to the first side wall 1111. In this case, the first distance between the first side wall 1111 and the second portion 112 is greater than the second distance between a portion of the side wall section of the second side wall 121 and the second portion 112. Figure 3 and Figure 6 For example, the partial sidewall segment indicates the partial sidewall segment of the second sidewall 121 in the z direction. In this case, the surface of the second sidewall 121 may be processed, or the shape of the second sidewall 121 may be adjusted to realize the reflection of the light incident on the baffle 12 to outside the display area. For example, the first distance between the first sidewall 1111 and the second part 112 is greater than the second distance between the partial sidewall segment of the second sidewall 121 and the second part 112, and the second distance between the partial sidewall segment of the second sidewall 121 close to the first sidewall 1111 and the second part 112 may be equal to the first distance; and the second distance between the partial sidewall segment far from the first sidewall 1111 and the second part 112 is less than the first distance, and the partial sidewall segment of the second sidewall 121 close to the first sidewall 1111 may be set as a rough surface, and the light is reflected outside the display area by diffuse reflection, and the partial sidewall segment far from the first sidewall 1111 may be changed in shape so that the incident light can be reflected outside the display area.

[0062] By using the rubber frame assembly provided in the embodiment of the present disclosure, the second side wall 121 of the baffle 12 is retracted relative to the first side wall 1111 of the first part 111, making it difficult for light to enter the baffle 12 or reflecting the light entering the second side wall 121 to the non-display area, thereby avoiding short bright lines at the edge of the display area and improving the user viewing experience.

[0063] In the present disclosure, only the position of the second side wall 121 in the retaining wall 12 may be adjusted so that light does not enter the area where the second side wall 121 is located, or the position and shape of the second side wall 121 may be adjusted so that light entering the second side wall 121 is reflected to an area other than the display area.

[0064] In the case where only the position of the second side wall 121 in the retaining wall 12 is adjusted, refer to Figure 4 , Figure 4 A cross-sectional view of a plastic frame assembly provided by an embodiment of the present disclosure is shown, Figure 4 As shown, the first distance between the first side wall 1111 and the second portion 112 is greater than the second distance between the second side wall 121 and the second portion 112, and the difference between the first distance and the second distance is greater than the dimension of the retaining wall 12 in the normal direction of the first portion 111. The normal direction is Figure 4 The direction indicated by the arrow on the z-axis.

[0065] In this embodiment, the difference between the first distance and the second distance is greater than the dimension of the retaining wall 12 in the normal direction of the first portion 111, indicating that the retracted distance of the second side wall 121 of the retaining wall 12 is greater than the height of the retaining wall 12. The optical path of the light incident at a 45-degree angle is as follows: Figure 5 As shown, the direction indicated by the dotted arrow is the direction of light propagation. At this time, the light passing through the vertex of the first side wall 1111 will not be incident on the area where the baffle wall 12 is located, and will not cause short bright lines to be generated in the display area, thereby eliminating the short bright lines generated in the display area and improving the user viewing experience.

[0066] When both the position and shape of the second side wall 121 are adjusted, the angle at which the light incident to the second side wall 121 is reflected can be changed by adjusting the position and shape, so that the light incident to the second side wall 121 is reflected outside the display area.

[0067] In one embodiment, referring to Figure 6 and Figure 8 ,in, Figure 8 A cross-sectional view of a plastic frame assembly provided in another embodiment of the present disclosure is shown. Figure 6 and Figure 8 As shown, in the normal direction of the first portion 111 , the difference between the first distance and the second distance gradually increases, that is, in the direction indicated by the arrow of the coordinate axis z, the difference between the first distance and the second distance gradually increases.

[0068] Specifically, when the difference between the first distance and the second distance is not greater than the size of the baffle wall 12 in the normal direction of the first portion 111, if the second side wall 121 of the baffle wall 12 is perpendicular to the first portion 111, the light incident on the second side wall 121 will still be reflected to the display area. Therefore, by changing the shape of the second side wall 121 so that the second distance between it and the second portion 112 gradually increases, the difference between the first distance and the second distance gradually increases. In this way, the reflection angle of the light incident on the second side wall 121 can be changed so that it falls outside the display area.

[0069] It can be understood that when the difference between the first distance and the second distance is greater than the size of the retaining wall 12 in the normal direction of the first part 111, the shape of the retaining wall 12 can also be improved. In this case, the difference between the first distance and the second distance gradually increases. At this time, the volume of the retaining wall 12 is smaller than that when the second side wall 121 is perpendicular to the first part 111, thereby reducing material consumption while realizing the function of the retaining wall 12.

[0070] The difference between the first distance and the second distance may increase linearly, such as Figure 8 As shown, it can also be a nonlinear increase, such as Figure 6It is understood that the shape of the second side wall 121 is not limited to Figure 6 and Figure 8 In the case shown, other linearly increasing or nonlinearly increasing shapes may also be used. In the case where the difference between the first distance and the second distance increases linearly, the second side wall 121 may be tilted, and in the case where the difference between the first distance and the second distance increases nonlinearly, the second side wall 121 may be a curved surface with a certain curvature, or a stepped surface, etc., so as to reflect the light incident on the second side wall 121 outside the display area.

[0071] The following specifically describes the case where the difference between the first distance and the second distance increases nonlinearly and the case where the difference between the first distance and the second distance increases linearly:

[0072] If the difference between the first distance and the second distance increases nonlinearly, the second side wall 121 may be a curved surface with a certain curvature, and the light incident on the second side wall 121 is reflected outside the display area by the curved surface with a certain curvature. It may also be a step surface, and the distance between the two steps is greater than the height of each step to prevent the light from being incident on the second side wall 121, or to reflect the light incident on the second side wall 121 outside the display area.

[0073] In one embodiment, continue to refer to Figure 6 The orthographic projection of the second side wall 121 on the target plane includes an arc segment, and the radius corresponding to the arc segment is smaller than the first dimension of the retaining wall 12 in the normal direction; wherein the target plane is a plane parallel to the normal direction.

[0074] Specifically, refer to Figure 7 , Figure 7 Shows the light incident Figure 6 The light path diagram of the second side wall 121 is as follows: Figure 7 As shown, after the light is incident on the second side wall 121, it is reflected in the arc segment and is reflected to the non-display area, thereby eliminating the short bright line in the display area. The radius of the arc segment is smaller than the first dimension of the retaining wall 12 in the normal direction, so that the arc segment only includes a curved surface, so that the light incident on the second side wall 121 will not be reflected to the display area.

[0075] Among them, the orthographic projection of the second side wall 121 on the target plane can also include multiple arc segments, each arc segment is connected to each other, wherein the arc segment close to the first side wall 1111 can have a larger curvature, while the arc segment far from the first side wall 1111 can have a smaller curvature. In this way, the light incident near the first side wall 1111 is reflected outside the display area by the arc segment with a larger curvature, and the light incident far from the first side wall 1111 is reflected outside the display area by the arc segment with a smaller curvature. Of course, the curvatures of multiple arc segments can also be the same, so that the light incident on the second side wall 121 can be reflected outside the display area.

[0076] It should be noted that the minimum difference between the first distance and the second distance is greater than the difference between the first size and the radius corresponding to the arc segment. By limiting the minimum difference between the first distance and the second distance, the problem of the distance between the first side wall 1111 and the second side wall 121 being too small, which makes it difficult to apply in the actual production process, can be prevented.

[0077] If the difference between the first distance and the second distance increases linearly, the second side wall 121 may be an inclined segment, wherein the inclination angle is such that the light incident on the second side wall 121 can be reflected to an area other than the display area.

[0078] Specifically, continue to refer to Figure 8 , the orthographic projection of the second side wall 121 on the target plane and the orthographic projection of the first portion 111 on the target plane have an angle greater than 45°; wherein the target plane is a plane parallel to the normal direction, that is, Figure 8 The coordinate axes shown in the figure are the plane formed by the y-axis and the z-axis.

[0079] In this embodiment, there is an angle between the orthographic projection of the second side wall 121 on the target plane and the orthographic projection of the first portion 111 on the target plane, indicating that the second side wall 121 is an inclined section that is inclined upward along the direction from the first side wall 1111 to the second portion 112, and when the slope of the inclined section is greater than 45 degrees, the light may not be incident on the second side wall, or the light may be incident on the second side wall 121 and reflected by the second side wall 121 to an area other than the display area. Among them, when the second side wall 121 is retracted to a smaller size, the light incident on the second side wall 121 can be reflected to the non-display area, and when the second side wall 121 is retracted to a larger size, the light will not be incident on the second side wall 121, but will be directly transmitted to the non-display area.

[0080] For example, Figure 8 As shown, the direction indicated by the dotted arrow is the direction of light propagation. After the light is incident on the second side wall 121, it is reflected to the non-display area of ​​the display panel, so that there will be no short bright line at the edge of the display area, thereby improving the user's viewing experience.

[0081] In one example, the second side wall 121 may also include a plurality of inclined sections, and the slope of each inclined section may be different, such as the inclined section close to the first side wall 1111 has a larger slope, while the inclined section far from the first side wall 1111 has a smaller slope. Then, at a position close to the first side wall 1111, light can be incident on the second side wall 121 and reflected by the second side wall 121 to the non-display area of ​​the display panel, while at a position far from the first side wall 1111, light will not be incident on the second side wall 121, but directly enter the non-display area, thereby eliminating the short bright line at the edge of the display area. Of course, two adjacent inclined sections in the second side wall 121 may also be connected with a platform section, and the slope of each inclined section is the same, which can also eliminate the short bright line at the edge of the display area.

[0082] It is understandable that the retaining wall 12 can be located at a position where two adjacent frames of the plastic frame 11 are connected to each other. Figure 2 By setting a retaining wall 12 at the position of the L-shaped area in the plastic frame 11, the elastic strip 13 located between the retaining wall 12 and the second part 112 can be fixed. The retaining wall 12 can be set only in the L-shaped area to avoid material waste.

[0083] It should be noted that the plastic frame 11 is used in conjunction with the elastic material to prevent the display panel embedded in the plastic frame 11 from being damaged by impact. For details, please refer to Fig. 9 , Fig. 9 A cross-sectional view of a plastic frame assembly provided in another embodiment of the present disclosure is shown. Fig. 9 As shown, the rubber frame assembly also includes an elastic strip 13, which is located in the area surrounded by the retaining wall 12 and the second part 112; wherein the first dimension of the retaining wall 12 in the normal direction of the first part 111 is less than or equal to the second dimension of the elastic strip 13 in the normal direction.

[0084] In this embodiment, when the first distance between the first side wall 1111 and the second part 112 is greater than the second distance between the second side wall 121 and the second part 112, the size of the elastic strip 13 in the direction perpendicular to the normal line needs to be considered. The elastic strip 13 needs to be accommodated in the area enclosed by the retaining wall 12 and the second part 112. When determining the difference between the first distance and the second distance, the size of the area enclosed by the retaining wall 12 and the second part 112 in the direction perpendicular to the normal line cannot be less than the size of the elastic strip 13 in the direction perpendicular to the normal line. In addition, in order to enable the elastic strip 13 to carry the display panel and thus reduce the risk of damage to the display panel, the size of the retaining wall 12 in the normal line direction is less than or equal to the size of the elastic strip 13 in the normal line direction. The elastic strip 13 can be foam or other elastic materials.

[0085] Among them, the size of the baffle wall 12 in the normal direction cannot be too low. If the size of the baffle wall 12 in the normal direction is too low, it will be difficult to restrict the elastic strip 13, which may cause the elastic strip 13 to jump out of the area enclosed by the baffle wall 12 and the second part 112, blocking the transmission of light to the display area and increasing the risk of damage to the display panel.

[0086] Specifically, the ratio between the first size and the second size can be 1 / 3 to 1 / 2. Within this ratio range, the retaining wall 12 can block the elastic strip 13, preventing the elastic strip 13 from jumping out of the area enclosed by the retaining wall 12 and the second part 112, and can facilitate the elastic strip 13 to carry the display panel. At the same time, it can also save material for the retaining wall 12.

[0087] For example, the ratio between the first size and the second size may be 1 / 3;

[0088] The ratio between the first size and the second size may be 5 / 12;

[0089] The ratio between the first size and the second size may be 1 / 2.

[0090] In one embodiment, in order to improve the limiting effect of the retaining wall 12 on the elastic strip 13, the side of the retaining wall 12 close to the elastic strip 13 can also be improved, referring to Fig.10 , Fig.10 A cross-sectional view of the plastic frame assembly provided in this embodiment is shown. Fig.10 As shown, the side of the retaining wall 12 close to the elastic strip 13 is recessed in a direction away from the elastic strip 13. Of course, the side of the retaining wall 12 close to the elastic strip 13 is not limited to the following. Fig.10 The curved surface shown in the figure may also be an inclined surface, and it only needs to be recessed in the direction away from the elastic strip 13. Specifically, the side of the retaining wall 12 close to the elastic strip 13 adopts a structure recessed in the direction away from the elastic strip 13, which can reduce the contact area between the retaining wall 12 and the elastic strip 13, so that the elastic strip 13 is difficult to escape from the area surrounded by the retaining wall 12 and the second part 112 along the side of the retaining wall 12 close to the elastic strip 13, so that the retaining wall 12 has a better limiting effect on the elastic strip 13.

[0091] By adopting the rubber frame assembly provided in this embodiment, by adjusting the second distance between the second side wall 121 and the second part 112 to be smaller than the first distance between the first side wall 1111 and the second part 112, and the difference between the first distance and the second distance is larger than the size of the retaining wall 12 in the normal direction, the light at a 45-degree angle will not be incident on the second side wall 121, but will be directly transmitted to the non-display area of ​​the display panel, thereby eliminating the short bright line at the edge of the display area of ​​the display panel; or the second distance between the second side wall 121 and the second part 112 is adjusted to be smaller than the first distance between the first side wall 1111 and the second part 112, and the difference between the first distance and the second distance is gradually increased, so that the light at a 45-degree angle is reflected to an area other than the display area of ​​the display panel after being incident on the second side wall 121, thereby eliminating the short bright line at the edge of the display area of ​​the display panel, thereby improving the viewing experience of the user.

[0092] In another embodiment, the plastic frame assembly can also be Fig.11 and Fig.12 As shown, in this embodiment, each frame in the plastic frame assembly can be provided with a retaining wall 12, and the retaining wall 12 extends along the length direction of the frame, and also encloses a frame-type structure. Therefore, when there are retaining walls 12 on all sides, the edges on all sides can receive the light reflected by the retaining walls 12, so that there is no short bright line; wherein, Fig.11 The structure diagram of the plastic frame assembly provided by the embodiment of the present disclosure is shown. Fig.12 Shows Fig.11 Cross-sectional view of the middle rubber frame assembly, according to Fig.11 and Fig.12 , the specific structure of the rubber frame assembly includes:

[0093] The rubber frame 11 is a frame-type structure, and each frame edge of the rubber frame 11 includes a first part 111 and a second part 112 connected in an L shape, wherein the first part 111 has a first side wall 1111 away from the second part 112; and a retaining wall 12, which is connected to the first part 111 of each frame edge and extends along the direction of the frame; wherein the retaining wall 12 is arranged opposite to the second part 112, and the retaining wall 12 has a second side wall 121 away from the second part 112, and the first distance between the first side wall 1111 and the second part 112 is equal to the second distance between the first side wall 111 and the second part 12.

[0094] In the present embodiment, by setting a baffle wall 12 on each frame of the rubber frame 11, the second side wall 121 of the baffle wall 12 set on each frame will reflect the light incident at a 45° angle to the edge of the display area of ​​the display panel. Since the brightness of the edges of the display area is consistent, the edge of the display area observed by the user does not have the problem of higher brightness in some areas, and the short bright lines observed by the user can also be eliminated, thereby improving the user's viewing experience.

[0095] By adopting this embodiment, it is possible to avoid improving the second side wall 121 of the retaining wall 12, thereby improving manufacturing efficiency. Of course, in this embodiment, in order to ensure the size of the area where the non-bright line of the display area is located, the second side wall 121 of the retaining wall 12 can still be improved, such as shrinking the retaining walls 12 on all sides, or changing the shape of the second side wall 121 of the retaining wall 12. For example, the shrinking size of each retaining wall 12 relative to the first side wall 1111 can be larger than the size of the retaining wall 12 in the normal direction, or the second side wall 121 of the retaining wall 12 can be adjusted to an arc surface while shrinking the second side wall 121 of the retaining wall 12, or the second side wall 121 of the retaining wall 12 can be adjusted to an inclined surface while shrinking the second side wall 121 of the retaining wall 12.

[0096] In one embodiment, the second side wall 121 may also be coated with a diffuse reflection film, which can scatter light incident at a 45-degree angle to all directions, thereby preventing the light from being reflected to the display area of ​​the display panel. The brightness of the edge area of ​​the display area is more consistent with that of other areas, thereby improving the user viewing experience.

[0097] By adopting the rubber frame assembly provided by the embodiment of the present disclosure, by setting a baffle wall 12 on each frame of the rubber frame 11, the incident light can be reflected by the baffle walls 12 located on all sides to the display area of ​​the display panel. In this way, the brightness of the edge of the display area can be made consistent, and the user will not observe short bright lines, thereby improving the user experience. In addition, a diffuse reflection film can be laid on the second side wall 121. The diffuse reflection film can prevent the incident light from being reflected to the display area of ​​the display panel, so that the brightness of the edge area of ​​the display area is consistent with other areas, thereby improving the user's viewing experience.

[0098] The following is a detailed description of the plastic frame assembly provided by the present disclosure with reference to specific examples:

[0099] Example 1: a plastic frame assembly 1 is provided:

[0100] Reference Fig.13 , Fig.13 The schematic diagram of the position of the rubber frame assembly provided in this example shows that the orthographic projection of the second side wall 121 in the retaining wall 12 on the plane parallel to the normal direction of the first part 111 is an arc segment, such as Fig.13As shown, the minimum difference between the second distance between the second side wall 121 and the second part 112 in the retaining wall 12 and the first distance between the first side wall 1111 and the second part 112 of the first part 111 is a, and the difference a increases nonlinearly; the radius R corresponding to the arc segment is slightly smaller than the first dimension h of the retaining wall 12 in the normal direction of the first part 111, the second dimension of the elastic strip 13 in the normal direction of the first part 111 is H, the first dimension h is 1 / 3 to 1 / 2 of the second dimension H, and the width b of the retaining wall 12 can be 0.5mm, and of course it can also be around 0.5mm. For example, when the second dimension H of the foam is 0.8mm, the first dimension h of the retaining wall 12 is 0.35mm, then the radius R of the arc segment can be 0.3mm, and the minimum difference a between the first distance and the second distance is 0.1mm.

[0101] At this time, continue to refer to Figure 7 , the light incident on the second side wall 121 at an angle of 45 degrees is reflected by the second side wall 121. At this time, since the second side wall 121 is an arc segment, the emission angle of the reflected light is smaller than the emission angle of the light when the second side wall 121 is vertical, so that the light is reflected to the non-display area of ​​the display panel. In this way, the light incident on the edge of the display area will not increase, and no short bright line will appear at the edge of the display area, thereby improving the user experience.

[0102] Example 2, providing another plastic frame component 2:

[0103] Continue to refer to Figure 8 , the second side wall 121 in the retaining wall 12 is an inclined surface, such as Figure 8 As shown, at this time, the difference between the first distance between the first side wall 1111 and the second portion 112 and the second distance between the second side wall 121 and the second portion 112 increases linearly; wherein, taking the angle between the second side wall 121 and a side of the first portion 111 perpendicular to the first side wall 1111 as 60°, the light incident on the second side wall 121 is reflected on the second side wall 121, and since the inclination of the second side wall 121 is large, the angle between the incident light and the second side wall 121 is small, and the angle of the outgoing light is small, and then the outgoing light falls into the non-display area of ​​the display panel, thereby eliminating the short bright lines in the display area.

[0104] Example 3, providing another plastic frame component 3:

[0105] Continue to refer to Figure 4, the distance that the second side wall 121 in the baffle wall 12 is retracted relative to the first side wall 1111 is greater than the size of the baffle wall 12 in the normal direction. For example, if the height of the baffle wall 12 is 0.3 mm, and the difference between the first distance and the second distance is 0.4 mm, the light will not be incident on the position where the baffle wall 12 is located, but will directly enter the non-display area of ​​the display panel, thereby eliminating the short bright lines in the display area.

[0106] Example 4: another plastic frame component 4 is provided:

[0107] Continue to refer to Fig.11 and Fig.12 The baffle wall 12 is located at each frame of the plastic frame 11 and extends along the frame. In this case, the light incident on the second side wall 121 of the baffle wall 12 will be reflected to the edge area of ​​the display area of ​​the display panel. Since the baffle wall 12 is arranged on all sides of the plastic frame 11, there is light reflected by the baffle wall 12 on all sides of the display area. The brightness of the display area is consistent, and the user will not observe the short bright lines. It can also achieve the elimination of the short bright lines in the display area.

[0108] Based on the same inventive concept, the present disclosure also provides a display device, referring to Fig.14 , Fig.14 A cross-sectional view of a display device provided by an embodiment of the present disclosure is shown. Fig.14 As shown, the display device specifically includes:

[0109] The plastic frame assembly 1 described in any of the above embodiments; and the backlight module 2 and the display panel 3;

[0110] The plastic frame assembly 1 is located between the backlight module 2 and the display panel 3 , and the first portion 111 of the plastic frame assembly 1 carries the display panel 3 .

[0111] In this embodiment, light is emitted from the backlight module 2 and reflected at the non-display area of ​​the display panel 3 at the position of the baffle 12, and the plastic frame assembly 1 is located between the backlight module 2 and the display panel 3. Among them, in the plastic frame assembly 1, the elastic strip 13 located in the first part 111 carries the display panel 3, so that the risk of damage to the display panel 3 can be reduced by the elastic strip 13.

[0112] Specifically, refer to Fig.14The display panel 3 is divided into a display area and a non-display area by the dotted line in the figure, wherein the display panel 3 located on the left side of the dotted line is the display area, and the display panel 3 located on the right side of the dotted line is the non-display area. When the incident baffle 12 of the backlight module 2 is located at the position, it is reflected by the second side wall 121 to the non-display area, and the first side wall 1111 reflects the light to the display area, so that the width of the bright line in the display area can be kept unchanged, thereby avoiding the problem that the user can observe a short bright line at the edge of the display panel 3 and reduce the user experience.
