[0056] To make the objectives, technical solutions, and advantages of the present application clearer, the following will further describe the embodiments of the present application in detail in conjunction with the drawings.

[0057] Figure 1 is a partial cross-sectional schematic diagram of a display device provided by an embodiment of the present application. Refer to Figure 1, the display device 100 includes a display panel 10 and a lighting device 20. The display panel 10 has a display side and a non-display side. The lighting device 20 includes: a housing 201, a lamp bar fixing member 202, a lamp bar assembly 203, and a light guide member 204.

[0058] Wherein, the housing 201 has a first accommodation space 201a. The lamp bar fixing member 202 is located within the first accommodation space 201a, and both ends of the lamp bar fixing member 202 are relatively fixed to the position of the housing 201. There is a second accommodation space M between the part between the two ends of the lamp bar fixing member 202 and the housing 201.

[0059] The lamp bar assembly 203 is located within the second accommodation space M and is fixedly connected to the lamp bar fixing member 202. Moreover, the lamp bar assembly 203 includes a light-emitting unit 2031, and the light emitted by the light-emitting unit 2031 is directed towards the housing 201.

[0060] The light guide member 204 is located on the light-emitting side of the light-emitting unit 2031 and is fixedly connected to the housing 201. The housing 201 has an opening K, and the position of the opening K is opposite to the position of the light-emitting unit 2031. The light guide member 204 is located within the opening K and is fixedly connected to the side wall of the opening K. The light emitted by the light-emitting unit 2031 is emitted after passing through the light guide member 204. Among them, the function of the light guide member 204 is to homogenize the light emitted by the light-emitting unit 2031 or display a pattern.

[0061] Optionally, the light guide member 204 can be designed to have different transmittances according to the needs of different users, so that the effects of the light emitted from the light guide member 204 are different. Or, the light guide member 204 can be designed to have different patterns according to the needs of different users, so that the light emitted from the light guide member 204 presents a pattern-like effect.

[0062] In summary, the embodiment of the present application provides a display device. The display device includes a lighting device, and the lamp bar assembly in the lighting device includes a light-emitting unit, and the light-emitting unit can be used to emit light. Thus, in addition to being used for displaying images, the display device can also emit light, improving the flexibility of the display device and being able to meet the display needs of different users. Moreover, since the lighting device is provided independently of the display panel, it will not affect the border width of the display panel, facilitating the realization of products with narrow borders.

[0063] Reference Figure 2 , the lamp bar assembly 203 further includes a connection terminal 2032. The connection terminal 2032 can be connected to the light-emitting unit 2031, and the connection terminal 2032 can be used to provide a signal from the driving system 30 to the light-emitting unit 2031, thereby realizing the light emission of the light-emitting unit 2031.

[0064] Optionally, the light bar assembly 203 may include a plurality of light emitting units 2031, and each of the plurality of light emitting units 2031 is capable of emitting a plurality of different colors of light. Thus, the display device can emit a plurality of different colors of light, and the flexibility of the display device 100 is relatively good.

[0065] Reference Figure 3 , the light guide member 204 includes a first part 2041 and a second part 2042 that are integrally formed. The orthographic projection of the second part 2042 on the first part 2041 is located within the first part 2041. The second part 2042 is located within the opening K and is fixedly connected to the side wall of the opening K. By fixedly connecting the second part 2042 to the side wall of the opening K, the light guide member 204 is fixedly connected to the housing 201.

[0066] Optionally, the width of the first part 2041 is greater than the width of the opening K, and the first part 2041 is located within the first accommodation space 201a. Combining Figure 1 and Figure 3 , the cross-sectional shape of the light guide member 204 may be in a T shape. Among them, the light guide member 204 may be a strip-shaped light guide member. For example, both the first part 2041 and the second part 2042 of the light guide member 204 are strip-shaped parts.

[0067] The length of the first part 2041 may refer to the dimension of the first part 2041 along the extending direction of the light guide member 204, and the width of the first part 2041 may refer to the dimension of the first part 2041 along a direction perpendicular to the extending direction of the light guide member 204 and perpendicular to the non-display side of the display panel 10.

[0068] By making the width of the first part 2041 of the light guide member 204 greater than the width of the opening K, it is possible to prevent the light guide member 204 from falling off from the position of the opening K, ensuring that the light emitted by the light emitting unit 2031 can pass through the light guide member 204 and then exit. In addition, the light guide member 204 can be snapped into the opening K and fixed with liquid glue.

[0069] In the embodiment of the present application, reference Figure 2 , the connection terminal 2032 includes a connection port (not shown in the figure) corresponding to the light emitting unit 2031. The light bar assembly 203 further includes a connection trace (not shown in the figure) corresponding to the light emitting unit 2031 and a strip-shaped support member 2033. One end of the connection trace is connected to the light emitting unit 2031, and the other end is connected to the corresponding connection port. The light emitting unit 2031 and the connection trace are both located on one side of the support member 2033, and the other side of the support member 2033 is connected to the light bar fixing member 202.

[0070] Optionally, when the light bar assembly 203 includes a plurality of light emitting units 2031, the light bar assembly 203 may include a plurality of connection traces corresponding to the plurality of light emitting units 2031, and one end of each connection trace is connected to the corresponding light emitting unit 2031.

[0071] Optionally, the light bar assembly 203 includes a plurality of light emitting unit groups Z arranged at intervals, and each light emitting unit group Z in the plurality of light emitting unit groups Z includes a target number of light emitting units 2031. The light bar assembly 203 includes a multiple of the target number of light emitting units 2031. That is, when the light bar assembly 203 includes a plurality of light emitting units 2031, the plurality of light emitting units 2031 may form a plurality of light emitting unit groups Z arranged at intervals. Among them, one light emitting unit group Z may be composed of a target number of light emitting units 2031. The number of light emitting units 2031 included in the light bar assembly 203 (that is, the number of light emitting units 2031 included in the plurality of light emitting unit groups Z) may be a multiple of the target number.

[0072] Exemplarily, assuming the target value is 6, each light emitting unit group Z includes 6 light emitting units 2031, and the number of light emitting units 2031 included in the light bar assembly 203 may be an integer multiple of 6. For example, it may be 10 times, and the number of light emitting units 2031 included in the light bar assembly 203 is 60. Of course, the target number may also be other integer values, such as 3, 4, 5, 6, 7, 8, etc. The specific value of the target value is not specifically limited in the embodiments of the present application.

[0073] Among them, the orthographic projection of the target light emitting unit group Z on the support member 2033 on the side away from the connection terminal is located within the support member 2033, and the distance between the orthographic projection of the target light emitting unit group Z on the support member 2033 on the side away from the connection terminal and the side wall of the support member 2033 away from the connection terminal is less than the interval. The target light emitting unit group Z is the light emitting unit group Z that is farthest from the connection terminal among the plurality of light emitting unit groups Z.

[0074] Optionally, the light bar assembly 203 may be cut from a light bar roll material. The light bar roll material may include a plurality of light emitting unit groups Z. When forming the light bar assembly 203, cutting may be performed along the interval between two adjacent light emitting unit groups Z in the light bar roll material. Thus, the obtained light bar assembly 203 may include a plurality of light emitting unit groups Z. The number of light emitting unit groups Z included in the light bar assembly 203 may be less than or equal to the number of light emitting unit groups Z included in the light bar roll material.

[0075] In the embodiments of the present application, referring to Figure 1 , the housing 201 includes: a first housing portion 2011, a second housing portion 2012, and a third housing portion 2013. The first housing portion 2011 is located on the non-display side of the display panel 10. Referring toFigure 4 The second housing part 2012 includes a first sub-part 20121, a second sub-part 20122, and a third sub-part 20123 that are integrally structured. The first sub-part 20121 is connected to the side of the first housing part 2011 away from the display panel 10, and the second sub-part 20122 intersects the non-display side. The orthographic projection of the second sub-part 20122 on the first housing part 2011 is located in the edge area of the first housing part 2011, and the second sub-part 20122 has an opening K. At least part of the orthographic projection of the third sub-part 20123 on the first housing part 2011 is located outside the first housing part 2011. The third housing part 2013 is connected to the first housing part 2011 and the second housing part 2012. That is, the housing 201 can be an assembly with an accommodation space formed by connecting multiple parts together.

[0076] Among them, the edge area of the first housing part 2011 may refer to the area near the edge in the first housing part 2011. Optionally, one of the edges of the edge area may be the bottom edge of the first housing part 2011.

[0077] Reference Figure 5 The light bar fixing member 202 is located on the side of the second housing part 2012 away from the display panel 10. The light bar fixing member 202 includes a first fixing part 2021, a second fixing part 2022, and a third fixing part 2023.

[0078] The first fixing part 2021, the second fixing part 2022, and the third fixing part 2023 are connected in a Z shape. The first end of the first fixing part 2021 is fixedly connected to the first sub-part 20121, the second end of the first fixing part 2021 is connected to the first end of the second fixing part 2022, the second end of the second fixing part 2022 is connected to the third fixing part 2023, and the third fixing part 2023 is fixedly connected to the third sub-part 20123.

[0079] There is a gap between the second fixing part 2022 and the second sub-part 20122, and the gap forms a second accommodation space M. That is, the light bar fixing member 202 and the light bar assembly 203 are both located between the second fixing part 2022 and the second sub-part 20122.

[0080] In the embodiment of the present application, since an opening K needs to be designed to place the light guide member 204, and the opening K is designed on the second sub-part 20122 of the second housing part 2012 of the housing 201, it will affect the device strength of the second sub-part 20122 and may affect the product yield. Therefore, in order to avoid a greater impact of the opening K on the device strength of the second sub-part 20122, the length of the opening K can be designed to be shorter.

[0081] Optionally, the opening K may be a strip-shaped opening, and the length of the opening K in the target direction is less than 1 / 3 of the length of the housing 201 in the target direction. The target direction may be the extending direction of the opening K, or, since the opening K is used to arrange the light guide member 204, the target direction may also be the extending direction of the light guide member 204. In Figure 1 In the illustrated embodiment, the light bar assembly 203 is adhesively bonded to the light bar fixing member 202 with glue, and both ends of the light bar fixing member 202 are fixedly connected to the housing 201 by screws respectively. For example, both ends of the light bar fixing member 202 are fixedly connected to the first sub-part 20121 and the third sub-part 20123 of the second housing part 2012 of the housing 201 respectively. In addition, the second housing part 2012 and the first housing part 2011 of the housing 201 may also be fixedly connected by screws.

[0082] In the embodiments of the present application, referring to Figure 6 and Figure 7 , the second housing part 2012 further includes: a fourth sub-part 20124 and a fifth sub-part 20125. Among them, the fourth sub-part 20124 and the second sub-part 20122 are opposite in position, and the fourth sub-part 20124 is connected to the first sub-part 20121. The fifth sub-part 20125 and the first sub-part 20121 are opposite in position, and the fifth sub-part 20125 is connected to the third sub-part 20123 and the third sub-part 20123. The first sub-part 20121, the second sub-part 20122, the fifth sub-part 20125 and the fourth sub-part 20124 form a third accommodation space 2012a.

[0083] Since the second housing part 2012 forms the third accommodation space 2012a, in order to enable the second housing part 2012 to be connected to the first housing part 2011, a through hole 20125a needs to be provided on the fifth sub-part 20125. The through hole 20125a can be used for a connecting member to pass through, and the connecting member passes through the through hole 20125a to connect the first sub-part 20121 and the first housing part 2011.

[0084] For example, the first housing part 2011 and the first sub-part 20121 of the second housing part 2012 have connecting holes. When installing the second housing part 2012 and the first housing part 2011, the connecting member passes through the through hole 20125a on the fifth sub-part 20125, and passes through the connecting hole on the first sub-part 20121 and then connects to the connecting hole of the first housing part 2011, that is, the connection between the first sub-part 20121 of the second housing part 2012 and the first housing part 2011 is realized. That is to say, the through hole 20125a on the fifth sub-part 20125 can facilitate the connecting member to avoid interference when connecting the first sub-part 20121 and the first housing part 2011.

[0085] Reference Figure 6 , the light bar fixing member 202 is located in the third accommodation space 2012a. The light bar fixing member 202 includes a first fixing portion 2021, a second fixing portion 2022, and a third fixing portion 2023. Reference Figure 8 , the first fixing portion 2021, the second fixing portion 2022, and the third fixing portion 2023 are connected in a U shape. The first end of the first fixing portion 2021 is fixedly connected to the first sub-portion 20121, the second end of the first fixing portion 2021 is connected to the first end of the second fixing portion 2022, and the second end of the second fixing portion 2022 is connected to the third fixing portion 2023.

[0086] Wherein, there is a gap between the second fixing portion 2022 and the second sub-portion 20122, and the gap between the second fixing portion 2022 and the second sub-portion 20122 forms a second accommodation space M. One end of the first fixing portion 2021 away from the second fixing portion 2022 contacts the light guide member 204, and one end of the third fixing portion 2023 away from the second fixing portion 2022 contacts the light guide member 204.

[0087] Exemplarily, a through hole 20124a may be provided on the fourth sub-portion 20124 of the second housing portion 2012 of the second housing 201. After the fixing member passes through the through hole 20124a, it abuts against one side of the second fixing portion 2022 of the light bar fixing member 202, so that the first fixing portion 2021 and the third fixing portion 2023 of the light bar fixing member 202 contact the light guide member 204, thereby fixing the positions of the light bar fixing member 202 and the light guide member 204. That is, the positions of the first fixing portion 2021 of the light bar fixing member 202 and the first sub-portion 20121 can be relatively fixed, and the positions of the third fixing portion 2023 and the third sub-portion 20123 can be relatively fixed.

[0088] Since an opening K needs to be designed to place the light guide member 204, and the opening K is designed on the second sub-portion 20122 of the second housing portion 2012 of the housing 201, it will affect the device strength of the second sub-portion 20122 and may affect the product yield. Further, in the solution of the embodiment of the present application, the second housing portion 2012 of the housing 201 can improve the device strength of the second housing portion 2012 by designing the fourth sub-portion 20124 and the fifth sub-portion 20125, and can weaken the influence of the design of the opening K on the strength of the second housing portion 2012.

[0089] Thus, the length of the opening K along the target direction can be greater than or equal to 1 / 3 of the length of the housing 201 along the target direction. The target direction can be the extending direction of the opening K or the extending direction of the light guide member 204. Additionally, the length of the light guide member 204 is less than or equal to the length of the opening K, which can ensure that the second part 2042 of the light guide member 204 can be disposed within the opening K. Of course, in Figure 6 In the illustrated embodiment, the length of the opening K along the target direction can also be less than the length of the housing 201 along the target direction, and the embodiments of the present application do not limit this.

[0090] It should be noted that since the first sub - part 20121, the second sub - part 20122, the fourth sub - part 20124, and the fifth sub - part 20125 of the second housing part 2012 of the housing 201 form a closed third accommodation space 2012a, when assembling the light bar fixing member 202 and the light bar assembly 203 into the third accommodation space 2012a, the light bar fixing member 202 and the light bar assembly 203 can be inserted into the third accommodation space 2012a from the side.

[0091] Exemplarily, first, a connecting member (which can be a screw) passes through the through - hole 20125a on the fifth sub - part 20125 of the second housing part 2012 to connect the first sub - part 20121 and the first housing part 2011. Then, the light guide member 204 is inserted into the third accommodation space 2012a from the side, and the second part 2042 of the light guide member 204 is placed in the opening K of the second sub - part 20122. Then, the light bar fixing member 202 and the light bar assembly 203 are inserted into the third accommodation space 2012a from the side, and the light bar fixing member 202 is pressed against the light guide member 204 by a fixing member (which can be a screw) passing through the through - hole 20125a on the fourth sub - part 20124 of the second housing part 2012.

[0092] In the embodiments of the present application, according to Figure 1 and Figure 6 it can be seen that the shape of the cross - section of the second housing part 2012 is the same everywhere (i.e., equi - sectional). The second housing part 2012 can be prepared using a mold. Optionally, the second housing part 2012 shown in Figure 6 can be prepared using a mold. If it is necessary to obtain the second housing part 2012 shown in Figure 1 the fourth sub - part 20124 and the fifth sub - part 20125 can be directly cut off. Thus, there is no need to manufacture two different molds to separately prepare two second housing parts 2012, thereby enabling different solutions to be achieved at a lower cost and realizing low - cost compatibility.

And, refer to Figure 11 , and the light emitted by the light bar assembly 203 in the lighting device 20 can be directed downward of the display device 100.

[0095] Optionally, since the housing 201 forms the first accommodation space 201a, in order to reduce the overall space occupied by the driving system 30 and the lighting device 20, the driving system 30 can be located in the first accommodation space 201a.

[0096] Combined with Figure 10 , Figure 1 and Figure 6 , the display device 100 further includes: a voice component 40. The voice component 40 is located in the first accommodation space 201a, and the voice component 40 is connected to the driving system 30 and is used to play voice under the drive of the driving system 30.
