The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.
[0027] The disclosure below provides many different embodiments or examples to implement different structures of the present invention. In order to simplify the disclosure of the present invention, the parts and settings of specific examples are described below. Of course, they are only examples, and the purpose is not to limit the present invention. In addition, the present invention can repeat reference numbers and / or letters in different examples. This repetition is for the purpose of simplicity and clarity, and does not itself indicate the relationship between the various embodiments and / or settings discussed. In addition, the present invention provides various specific processes and examples of materials, but those of ordinary skill in the art can be aware of the applicability of other processes and / or the use of other materials.
[0028] A display module, such as a liquid crystal display module, is an electronic component used to display images and text. It consists of one or more liquid crystal screens that can display text, images, and other information. The working principle of a liquid crystal display module is that the liquid crystal screen consists of a series of small pixels composed of liquid crystal molecules. Each pixel has an electrode. When a voltage is applied to the electrode, the liquid crystal molecules emit light, thereby displaying images and text. The advantages of liquid crystal display modules are small size, low power consumption, fast response speed, can display a variety of colors, and can work at low temperatures, so they are widely used in electronic devices.
[0029] The LCD (liquid crystal display module) display principle is realized through the physical properties of liquid crystal. The LCD display module is composed of a liquid crystal cell, a backlight module, a driver IC and a control IC. The liquid crystal cell is composed of a thin film and an electrode. When a voltage is applied to the electrode, the liquid crystal molecules in the liquid crystal cell will change, thereby changing the light transmittance of the liquid crystal cell, thereby achieving a display effect. The backlight module is composed of one or more LEDs. When the LED emits light, the liquid crystal molecules in the liquid crystal cell will change, thereby changing the light transmittance of the liquid crystal cell, thereby achieving a display effect. The driver IC and the control IC are used to control the brightness of the LED and the voltage of the liquid crystal cell to achieve a display effect.
[0030] The display module is formed by connecting the panel bonding area on the side of the display panel facing the backlight frame, which may be a ring-shaped panel bonding area, with the backlight bonding area on the side of the backlight frame facing the display panel, which may be a ring-shaped backlight bonding area. Exemplarily, the panel bonding area and the backlight bonding area may be bonded by double-sided foam adhesive. Figure 1The backlight frame 21 is generally a plastic frame, and the flatness of the backlight bonding area is poor, so that the panel bonding area may be partially warped after being bonded thereto. The liquid crystal at the warped location is easily deflected, making it easy for the backlight to penetrate through the deflected liquid crystal, thereby causing light leakage in the display module 100.
[0031] Based on this, the present invention proposes a display module 100, which improves the flatness of the surface in contact with the display bonding area 10a of the display panel 10 by setting a support member 30, so that the display panel 10 is not prone to local warping after bonding with it, thereby reducing light leakage of the display module 100.
[0032] Figure 2-Figure 5 FIG. 1 is a schematic diagram of the structure of a display module 100 according to an embodiment of the present invention. Figure 2-Figure 4 The display module 100 includes a display panel 10, and the display panel 10 is used to display images. The liquid crystal display panel uses the optical properties of liquid crystal molecules to realize image display. Specifically, the liquid crystal molecules change their orientation by applying an electric field, thereby controlling the penetration and blocking of light. Common liquid crystal display panels include TN panels, VA panels such as MVA and PVA, IPS panels, and CPA panels.
[0033] The display module 100 further includes a backlight assembly 20 located at one side of the display panel 10 . The backlight assembly 20 is used to supply a light source with sufficient brightness and uniform distribution so that the display panel 10 can display images normally.
[0034] The backlight assembly 20 includes a backlight frame 21 . Exemplarily, the backlight frame 21 may be a PC plastic frame.
[0035] The backlight frame 21 has a backlight fitting surface 21a facing the display panel 10, and the display panel 10 has a display fitting area 10a corresponding to the backlight fitting surface 21a on the side facing the backlight assembly 20. The backlight fitting surface 21a is connected to the display fitting area 10a to connect the backlight assembly 20 and the display panel 10 together. Exemplarily, the backlight fitting surface 21a can be annular to avoid light. The display fitting area 10a can be annular to avoid light. The backlight fitting surface 21a and the display fitting area 10a can be bonded by a connector 40, such as a double-sided adhesive. Of course, it can be understood that the backlight fitting surface 21a and the display fitting area 10a can also be set to other shapes, and the backlight fitting surface 21a can be a light-transmitting material so that light can pass through.
[0036] The display module 100 further includes a support member 30, which has a first surface 30a facing the backlight fitting surface 21a and connected to the backlight fitting surface 21a, and a second surface 30b facing the display fitting area 10a and connected to the display fitting area 10a. The support member 30 is connected to the backlight fitting surface 21a through the first surface 30a, and the second surface 30b is connected to the display fitting surface, so as to connect the display panel 10 and the backlight assembly 20 together. Specifically, the first surface 30a of the support member 30 and the backlight fitting surface 21a can be bonded by double-sided adhesive. The second surface 30b of the support member 30 and the display fitting area 10a can be bonded by double-sided adhesive.
[0037] The strength of the support member 30 is higher than that of the backlight frame 21, so that the support member 30 itself is not easily deformed and can maintain the flatness of its own structure. At the same time, the flatness of the support member 30 at least on the second surface 30b is higher than that of the backlight bonding surface 21a, so that after the display panel 10 is connected to it, it is not easy to be locally warped, and the liquid crystal is not easy to be deflected, so that the backlight is not easy to be transmitted, the occurrence of light leakage is reduced, and the display quality of the display panel 10 is improved.
[0038] Therefore, refer to Figure 2-Figure 4 According to the display module 100 of the present invention, by providing a support member 30, the support member 30 has a first surface 30a facing the backlight bonding surface 21a and connected to the backlight bonding surface 21a, and a second surface 30b facing the display bonding area 10a and connected to the display bonding area 10a, so that the backlight assembly 20 and the display panel 10 can be connected through the support member 30. At the same time, the strength of the support member 30 is higher than the strength of the backlight frame 21, and the flatness of the support member 30 at least on the second surface 30b is higher than the flatness of the backlight bonding surface 21a. In this way, after the display panel 10 is connected to the backlight assembly 20 through the support member 30, it is not easy to have local warping, and the liquid crystal is not easy to deflect, so that the backlight light is not easy to penetrate, the occurrence of light leakage is reduced, and the display quality of the display panel 10 is improved.
[0039] In some embodiments, the backlight frame 21 is disposed on one side of the display panel 10 and is annular; the cross section of the backlight frame 21 along the thickness direction of the display panel 10 may be L-shaped. The backlight frame 21 includes a first frame 211 connected to the support member 30 and a second frame 212 that forms a certain angle with the first frame 211, wherein the first frame 211 and the second frame 212 may form a right angle.
[0040] In some embodiments, reference Figure 2 The backlight assembly 20 further includes a light source, a light guide plate 70 and an optical film 60 .
[0041] The light source is arranged in the area surrounded by the backlight frame 21. The light source may be an electroluminescent light source, which is thin and light, provides uniform light, and has low power consumption; the light source may also be an LED light source, which has a long service life and uses a DC voltage. Of course, the present application is not limited thereto, and the light source may also be other light sources.
[0042] The light guide plate 70 is disposed in the area surrounded by the backlight frame 21 and between the light source and the display panel 10. The light guide plate 70 can be disposed parallel to the display panel 10. The light guide plate 70 is used to guide the scattering direction of light, improve the brightness of the display panel 10, and ensure the uniformity of the brightness of the display panel 10.
[0043] The optical film 60 is disposed on the side of the light guide plate 70 facing the display panel 10. The optical film 60 is used to improve the front view brightness, or axial brightness, of the liquid crystal module through the prism film, the reflective polarizer and the high reflectivity reflector under a certain light source output.
[0044] In some embodiments, the backlight assembly 20 also includes a back panel 50, and the cross-section of the back panel 50 along the thickness direction of the display panel 10 can be U-shaped, wherein the bottom surface of the back panel 50 is located on the side of the light guide plate 70 away from the display panel 10, and the side surface of the back panel 50 is located on the side of the second frame 212 of the backlight frame 21 facing the light guide plate 70.
[0045] In some embodiments of the present invention, the flatness of the first surface 30 a of the support member 30 is higher than the flatness of the backlight attaching surface 21 a .
[0046] By setting the flatness of the first surface 30a of the support member 30 to be higher than the flatness of the backlight bonding surface 21a, and at the same time, the strength of the support member 30 is higher than the strength of the backlight frame 21, the stability of the support member 30 between the backlight frame 21 and the display panel 10 can be improved. When the support member 30 and the backlight frame 21 are bonded by double-sided adhesive, the higher the flatness of the first surface 30a of the support member 30, the greater the connection strength.
[0047] It is understandable that the flatness of the other surfaces of the support member 30 except the first surface 30a and the second surface 30b may be higher than the flatness of the backlight fitting surface 21a, or may be close to the flatness of the backlight fitting surface 21a.
[0048] In some embodiments of the present invention, reference Figure 3 and Figure 5 The support member 30 includes a first support portion 31 and a second support portion 32 connected at a certain angle. The first support portion 31 is stacked between the display panel 10 and the backlight frame 21 and includes a first surface 30a and a second surface 30b. The second support portion 32 is connected to the backlight frame 21.
[0049] The support member 30 is configured to include a first support portion 31 and a second support portion 32 connected at a certain angle, so that the overall structural strength of the support member 30 is relatively large and not easily deformed. It is understandable that the angle between the first support portion 31 and the second support portion can be an acute angle, a right angle, an obtuse angle, etc.
[0050] The first support portion 31 includes a first surface 30a and a second surface 30b, and is stacked between the display panel 10 and the backlight frame 21 to connect the display panel 10 and the backlight frame 21. It can be understood that the first support portion 31 can be a plate-like structure, and the first surface 30a and the second surface 30b are respectively located on opposite sides of the plate-like structure, so that the overall thickness of the display module 100 can be reduced.
[0051] The second support portion 32 is connected to the backlight frame 21, which can improve the connection strength between the support member 30 and the backlight frame 21, so that the support member 30 is not easily deformed. It is understandable that the second support portion 32 can be connected to the outer side, inner side, or between the outer side and the inner side of the first frame 211 of the backlight frame 21.
[0052] Of course, the present application is not limited thereto, and in other embodiments, the support member 30 may also include only the first support portion 31, that is, the support member 30 is plate-shaped. In order to increase the strength of the support member 30 so that the support member 30 is not easily deformed, the thickness of the support member 30 may be increased.
[0053] It is understandable that the second support portion 32 can be connected to any position of the first support portion 31. Exemplarily, the second support portion 32 can be connected to one end of the first support portion 31 close to the inner circumference, or to one end of the first support portion 31 close to the outer circumference, or to any position between the outer circumference and the inner circumference of the first support portion 31.
[0054] In some embodiments of the present invention, reference Figure 3 and Figure 5 , the first supporting portion 31 and the second supporting portion 32 are perpendicular to each other.
[0055] The first support portion 31 and the second support portion 32 are arranged vertically, which is beneficial to improving the structural strength and stability of the support member 30 and is also convenient for production and processing.
[0056] It can be understood that the second support portion 32 can be connected to the end of the first support portion 31 facing outward, or to the end of the first support portion 31 facing inward, or to any position between the end of the first support portion 31 facing outward and the end facing inward.
[0057] In some embodiments of the present invention, the backlight frame 21 includes an annular first frame 211 , a backlight fitting surface 21 a is defined between the inner and outer peripheries of the first frame 211 , and the second support portion 32 is connected to the outer periphery of the first frame 211 .
[0058] The annular first frame 211 can be a circular ring, a square ring, etc., and can be set according to actual needs. The inner periphery of the annular first frame 211 can form a light avoidance hole, which is conducive to the passage of light.
[0059] The surface between the inner periphery and the outer periphery of the first frame 211 facing the display panel 10 is the backlight fitting surface 21a, which is convenient for connection through a connecting material or a connector 40 such as a double-sided adhesive tape. The double-sided adhesive tape can be bonded to the entire surface of the backlight fitting surface 21a, or to a portion of the backlight fitting surface 21a. Preferably, the double-sided adhesive tape is bonded to a portion of the backlight fitting surface 21a. The double-sided adhesive tape can be provided in an area of the backlight fitting surface 21a close to the periphery, or in an area of the backlight fitting surface 21a close to the periphery, or in an area between the outer periphery and the inner periphery of the backlight fitting surface 21a. Preferably, the double-sided adhesive tape is provided in an area between the outer periphery and the inner periphery of the backlight fitting surface 21a.
[0060] The second support portion 32 is connected to the outer periphery of the first frame 211 , which facilitates the connection between the second support portion 32 and the first frame 211 and ensures that the first frame 211 avoids light.
[0061] In some embodiments of the present invention, reference Figure 3 and Figure 5 The projection of a surface of the second supporting portion 32 away from the first frame 211 on the display panel 10 coincides with the edge of the display panel 10 , or is located inside the display panel 10 .
[0062] By arranging the projection of the second support portion 32 away from the first frame 211 on the display panel 10 to coincide with the edge of the display panel 10 or to be located inside the display panel 10 , the arrangement of the support member 30 will not increase the width of the display module 100 .
[0063] Preferably, the projection of the side of the second supporting portion 32 away from the first frame 211 on the display panel 10 coincides with the edge of the display panel 10, so that the space can be fully utilized to avoid a gap on the side of the display panel 10 facing the backlight assembly 20, thereby protecting the display panel 10. Considering the difficulty of machining accuracy, the projection of the side of the second supporting portion 32 away from the first frame 211 on the display panel 10 can be located inside the display panel 10, and at this time, the distance between the projection and the edge of the display panel 10 can be as small as possible to ensure the protection of the display panel 10.
[0064] In some embodiments of the present invention, reference Figure 3 and Figure 5 The backlight frame 21 further includes a second frame 212 , which is close to the outer periphery of the first frame 211 and vertically connected to the first frame 211 , and the second supporting portion 32 extends to the second frame 212 .
[0065] The second frame 212 is close to the outer periphery of the first frame 211 and is vertically connected to the first frame 211 to form an L-shaped backlight frame 21, which improves the structural strength of the backlight frame 21 and is beneficial to the side connection of the backlight frame 21 and the back panel 50, thereby improving the connection strength between the backlight frame 21 and the back panel 50.
[0066] The second support portion 32 extends to the second frame 212, which increases the length of the second support portion 32 and the contact area between the second support portion 32 and the backlight frame 21, thereby further increasing the connection strength between the support member 30 and the backlight frame 21, making the first support portion 31 less likely to deform.
[0067] It can be understood that the second support portion 32 can extend to any position of the second frame 212. Exemplarily, the second support portion 32 can extend to an end of the second frame 212 close to the first frame 211; it can also extend to an end of the second frame 212 away from the first frame 211. For example, the length of the second support portion 32 along the thickness direction of the display panel 10 can be equal to the sum of the thickness of the first frame 211 and the length of the second frame 212; it can also extend to any position in the middle of the second frame 212 along the thickness direction of the display panel 10. Preferably, the second support portion 32 extends to any position in the middle of the second frame 212 along the thickness direction of the display panel 10.
[0068] In some embodiments of the present invention, reference Figure 4 The side of the second frame 212 facing away from the inner periphery of the first frame 211 is a stepped surface, and in the direction from the inner periphery to the outer periphery of the first frame 211, the thickness of the second frame 212 close to the first frame 211 is less than the thickness of the end away from the first frame 211, so that the second support portion 32 extends to the second frame 212.
[0069] By setting a step surface on the side of the second frame 212 away from the inner periphery of the first frame 211, and in the direction from the inner periphery to the outer periphery of the first frame 211, the thickness of the second frame 212 close to the first frame 211 is less than the thickness of the end away from the first frame 211, thus, a gap that can accommodate the second support portion 32 is formed so that the second support portion 32 extends to the second frame 212.
[0070] It can be understood that, along the direction from the inner periphery of the first frame 211 to the outer periphery of the first frame 211, the thickness of the end of the second frame 212 away from the first frame 211 is the same as the sum of the thickness of the end of the second frame 212 close to the first frame 211 and the thickness of the second support portion 32. That is, the projection of the end of the second frame 212 away from the first frame 211 and away from the inner periphery of the first frame 211 on the display panel 10 coincides with the projection of the side of the second support portion 32 away from the inner periphery of the first frame 211 on the display panel 10. In this way, the integrity of the structure as a whole after the backlight frame 21 is connected to the support member 30, as well as the overall structural strength, are ensured.
[0071] It is understandable that the step surface includes a tread 211a and a riser 211b, and the second support portion 32 is connected to the tread 211a, and can be spaced apart from or connected to the riser 211b. Preferably, the second support portion 32 is spaced apart from the riser 211b to prevent the riser 211b from exerting a force on the second support portion 32, causing the first support portion to deform. At the same time, the second support portion 32 is spaced apart from the riser 211b to facilitate production and processing.
[0072] Of course, it is understandable that in some embodiments, a side of the second frame 212 away from the inner periphery of the first frame 211 may also be a plane. In this case, the second support portion 32 extends to an end of the second frame 212 away from the first frame 211 .
[0073] In some embodiments of the present invention, reference Figure 5 The backlight frame 21 includes an annular first frame 211 , a backlight fitting surface 21 a is provided between the inner periphery and the outer periphery of the first frame 211 , the backlight fitting surface 21 a has a groove 213 , and the second supporting portion 32 is connected to the groove 213 .
[0074] The annular first frame 211 can be a circular ring, a square ring, etc., and can be set according to actual needs. The inner periphery of the annular first frame 211 can form a light avoidance hole, which is conducive to the passage of light.
[0075] The surface between the inner periphery and the outer periphery of the first frame 211 facing the display panel 10 is the backlight fitting surface 21a, which is convenient for connection through a connecting material or a connector 40 such as a double-sided adhesive tape. The double-sided adhesive tape can be bonded to the entire surface of the backlight fitting surface 21a, or to a portion of the backlight fitting surface 21a. Preferably, the double-sided adhesive tape is bonded to a portion of the backlight fitting surface 21a. The double-sided adhesive tape can be provided in an area of the backlight fitting surface 21a close to the periphery, or in an area of the backlight fitting surface 21a close to the periphery, or in an area between the outer periphery and the inner periphery of the backlight fitting surface 21a. Preferably, the double-sided adhesive tape is provided in an area between the outer periphery and the inner periphery of the backlight fitting surface 21a.
[0076] By providing a groove 213 on the backlight fitting surface 21a and connecting the second support portion 32 to the groove 213, the second support portion 32 can be connected to the first frame 211 on both sides, thereby improving the connection strength between the support member 30 and the backlight frame 21. At this time, the second support portion 32 is connected between the inner periphery and the outer periphery of the first support portion 31. It is understandable that the second support portion 32 and the bottom surface of the groove 213 can be spaced apart or connected. Preferably, the second support portion 32 and the bottom surface of the groove 213 are spaced apart to avoid the bottom surface of the groove 213 exerting a force on the second support portion 32, causing the first support portion to deform. At the same time, the second support portion 32 and the kick surface 211b are spaced apart to facilitate production and processing.
[0077] In some embodiments, the backlight frame 21 also includes a second frame 212, and the second frame 212 can be connected to the inner periphery of the first frame 211, can be connected to the outer periphery of the first frame 211, or can be connected between the inner periphery and the outer periphery of the first frame 211. The second frame 212 can be connected to the first frame 211 at a certain angle. Exemplarily, the second frame 212 can be connected to the first frame 211 at an acute angle, an obtuse angle, or a right angle. Preferably, the second frame 212 is connected to the first frame 211 at a right angle. In this way, the first frame 211 and the second frame 212 can form a backlight frame 21 with a structure such as an L-type or a T-type, which improves the structural strength of the backlight frame 21, and is conducive to the side connection of the backlight frame 21 and the back plate 50, thereby improving the connection strength of the backlight frame 21 and the back plate 50.
[0078] The second support portion 32 may be connected only to the first frame 211, or may extend to the second frame 212. Preferably, the second support portion 32 extends to the second frame 212, which may increase the length of the second support portion 32 and the contact area between the second support portion 32 and the backlight frame 21, thereby further increasing the connection strength between the support member 30 and the backlight frame 21, and making it less likely for the first support portion 31 to deform.
[0079] It can be understood that the second support portion 32 can extend to any position of the second frame 212. Exemplarily, the second support portion 32 can extend to an end of the second frame 212 close to the first frame 211; it can also extend to an end of the second frame 212 away from the first frame 211. For example, the length of the second support portion 32 along the thickness direction of the display panel 10 can be equal to the sum of the thickness of the first frame 211 and the length of the second frame 212; it can also extend to any position in the middle of the second frame 212 along the thickness direction of the display panel 10. Preferably, the second support portion 32 extends to any position in the middle of the second frame 212 along the thickness direction of the display panel 10.
[0080] In some embodiments, the second support portion 32 may be one or more than two. When there is one second support portion 32, the first support portion 31 and the second support portion 32 may be connected to form an L-shaped structure or a T-shaped structure. When there are more than two second support portions 32, the more than two second support portions 32 may be arranged between the inner periphery and the outer periphery of the first support portion 31; one of them may be arranged close to the outer periphery of the first support portion 31, and the rest may be arranged between the inner periphery and the outer periphery of the first support portion 31; one of them may be arranged close to the inner periphery of the first support portion 31, and the rest may be arranged between the inner periphery and the outer periphery of the first support portion 31; when there are two second support portions 32, one of them may be arranged close to the outer periphery of the first support portion 31, and the other may be arranged close to the inner periphery of the first support portion 31; when there are more than three second support portions 32, one of them may be arranged close to the outer periphery of the first support portion 31, another one may be arranged close to the inner periphery of the first support portion 31, and the rest may be arranged between the inner periphery and the outer periphery of the first support portion 31, etc.
[0081] It is understandable that when there are more than two second support portions 32, the angles between the two or more second support portions 32 and the first support portion 31 may be the same or different. Preferably, the angle between the second support portion 32 close to the outer periphery or inner periphery of the first support portion 31 and the first support portion 31 is set to a right angle. The angle between the second support portion 32 disposed between the inner periphery and the outer periphery of the first support portion 31 and the first support portion 31 may be an acute angle, an obtuse angle, a right angle, etc. Preferably, the angle between the second support portion 32 disposed between the inner periphery and the outer periphery of the first support portion 31 and the first support portion 31 is a right angle. Among them, the second support portion 32 disposed between the inner periphery and the outer periphery of the first support portion 31 may be connected to the first frame 211, or may extend to the second frame 212. Preferably, the second support portion 32 disposed between the inner periphery and the outer periphery of the first support portion 31 extends to the second frame 212.
[0082] In some embodiments of the present invention, the support member 30 is made of metal or glass.
[0083] By using the support member 30 made of metal or glass, the strength of the support member 30 is higher than that of the backlight frame 21 made of glue, and the flatness is also higher.
[0084] When the material of the support member 30 is metal, it can be copper, aluminum, alloy, etc. When the material of the support member 30 is glass, it can be organic glass, inorganic glass, etc.
[0085] Of course, the present application is not limited thereto. In other embodiments, the support member 30 may also be made of other materials as long as the strength and flatness are higher than the colloid backlight frame 21 .
[0086] In some embodiments of the present invention, reference Figure 3 and Figure 5The first support portion 31 is annular, and the area formed by the inner circumference of the first support portion 31 is used to avoid light.
[0087] The first support portion 31 is set to be ring-shaped, and can be, for example, a square ring or a circular ring, etc. The area formed by the inner circumference thereof can avoid light, which is conducive to the light passing through.
[0088] It is understandable that the projection of the inner periphery of the first support portion 31 on the display panel 10 may be located within the projection of the first frame 211 on the display panel 10, or may coincide with the projection of the inner periphery of the first frame 211 on the display panel 10. Preferably, the projection of the inner periphery of the first support portion 31 on the display panel 10 is located within the projection of the first frame 211 on the display panel 10.
[0089] In some embodiments of the present invention, the support member 30 and the backlight frame 21 are formed in one piece.
[0090] By forming the support member 30 and the backlight frame 21 as an integral unit, the connection strength and connection reliability between the support member 30 and the backlight frame 21 are improved.
[0091] For example, when the support member 30 is made of metal and the backlight frame 21 is made of plastic, the support member 30 and the backlight frame 21 can be processed by iron-plastic integrated molding, that is, the support member 30 and the backlight frame 21 are placed in a mold for welding.
