Description

Technical Field

[0001] This application relates to the field of display technology, and in particular to a display module and a display terminal. Background Technology

[0002] OLED (Organic Light-Emitting Diode) display technology is a new type of display technology that has gradually attracted attention due to its unique advantages such as low power consumption, high saturation, fast response time and wide viewing angle. In particular, foldable display modules have been gradually developed and applied.

[0003] Foldable display modules typically require the installation of multiple sensors. Each sensor area needs a corresponding aperture, and different inks need to be printed inside and outside these apertures to ensure light transmission within the aperture area and opacity outside. Due to limitations in manufacturing precision, different inks overlap at their interfaces, resulting in uneven printing thickness. Furthermore, since foldable display modules mostly use organic films to meet bending requirements, and organic films have poor overall support properties, noticeable ink overprints remain after assembly, affecting the display effect.

[0004] Therefore, it is urgent to solve the above-mentioned technical problems. Summary of the Invention

[0005] This application provides a display module and a display terminal to improve the technical problem of obvious ink marks at the ink overprinting position of the display module, which affects the display effect.

[0006] To achieve the above objectives, according to a first aspect of this application, a display module is provided, comprising:

[0007] Cover plate body;

[0008] A light-shielding layer is disposed on one side surface of the cover plate body;

[0009] A display panel is disposed on the side of the light-shielding layer away from the main body of the cover plate. The display panel includes a display area and a non-display area disposed around the display area.

[0010] The light-shielding layer is provided corresponding to the non-display area, the display module has at least one light-transmitting area, the light-shielding layer has a plurality of first holes in the light-transmitting area, the first holes penetrate the light-shielding layer along the thickness direction of the light-shielding layer, and the light transmittance of the light-transmitting area ranges from 5% to 20%.

[0011] Optionally, the display module further includes a first functional layer that is disposed in contact with the side of the display panel opposite to the cover plate body;

[0012] The first functional layer is provided with a second hole corresponding to the light-transmitting area, and each first hole is located inside the second hole. The depth of the second hole is less than or equal to the thickness of the first functional layer.

[0013] Optionally, the first functional layer includes a stacked back plate layer and a support layer, wherein the support layer is disposed on the side of the back plate layer away from the cover plate body, and the modulus of the support layer is greater than that of the back plate layer.

[0014] Wherein, the depth of the second hole is equal to the thickness of the first functional layer, and the opening area of ​​the second hole on the back plate layer is smaller than the opening area of ​​the second hole on the support layer.

[0015] Optionally, the display panel is provided with a third hole communicating with the second hole, and the sidewall of the second hole on the back panel layer is flush with the sidewall of the third hole.

[0016] Optionally, there are multiple third holes, each of the first holes is located within a third hole, and the opening area of ​​the third hole is larger than the opening area of ​​the first hole.

[0017] Optionally, the display module includes a second functional layer that is disposed in contact with the display panel on the side near the cover plate body;

[0018] The second functional layer is provided with a fourth hole that communicates with the third hole, and the depth of the fourth hole is less than or equal to the thickness of the second functional layer.

[0019] Optionally, the depth of the fourth hole is less than the thickness of the second functional layer;

[0020] There are multiple fourth holes, and the sidewall of the fourth hole is flush with the sidewall of the third hole.

[0021] Optionally, the depth of the fourth hole is equal to the thickness of the second functional layer, the second functional layer comprising a stacked adhesive layer and a polarizer, the polarizer being located on the side of the adhesive layer opposite to the cover plate body;

[0022] The opening area of ​​the fourth hole on the polarizer is smaller than the opening area of ​​the fourth hole on the adhesive layer.

[0023] Optionally, the shape of the first hole includes a triangle, a quadrilateral, or a circle.

[0024] According to a second aspect of this application, a display terminal is provided, including the display module described above.

[0025] In the display module of this application embodiment, by providing multiple first holes in the area corresponding to the light-transmitting area on the light-shielding layer, light can pass through the first holes. The light transmittance of the light-transmitting area ranges from 5% to 20%, thereby ensuring that the light-transmitting area meets the light transmission requirements. With this arrangement, it is unnecessary to overprint light-transmitting ink within the light-transmitting area of ​​the light-shielding layer, thus improving the technical problem of obvious ink marks at the ink overprinting position in the display module, which affects the display effect.

[0046] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the protection scope of this application.

[0047] like Figures 1 to 8 As shown, according to a first aspect of this application, a display module 1 is provided, including a cover plate body 10, a light-shielding layer 20, and a display panel 30. The light-shielding layer 20 is disposed on one side surface of the cover plate body 10; the display panel 30 is disposed on the side of the light-shielding layer 20 away from the cover plate body 10, and the display panel 30 includes a display area AA and a non-display area NA disposed around the display area AA; wherein the light-shielding layer 20 is disposed corresponding to the non-display area NA, the display module 1 has at least one light-transmitting area 21, the light-shielding layer 20 has a plurality of first holes 22 in the light-transmitting area 21, the first holes 22 penetrate the light-shielding layer 20 along the thickness direction of the light-shielding layer 20, and the light transmittance of the light-transmitting area 21 ranges from 5% to 20%.

[0048] The cover plate body 10 can be a rigid cover plate body or a flexible cover plate body. The rigid cover plate body can be made of materials such as glass. The flexible cover plate body can be made of one of the following materials: colorless polyimide (PI), polycarbonate (PC), polynorbornene (PNB), and polyethylene terephthalate (PET). When the display panel 30 is a flexible panel, the cover plate body 10 can be a flexible cover plate body, making the display panel 30 easy to fold. The cover plate body 10 can protect the display panel 30 from damage caused by mechanical impact.

[0049] The display panel 30 can be an OLED panel, a Mini-LED panel, a Micro-LED panel, etc.

[0050] like Figure 1 As shown, the display panel 30 includes a display area AA and a non-display area NA disposed around the display area AA. The display area AA can be used to display images. The display area AA has multiple sub-pixels, such as red sub-pixels, green sub-pixels, and blue sub-pixels. Different colored sub-pixels can emit different colored light, thereby achieving color display. The non-display area NA may be provided with a driving circuit, such as a gate driving circuit. The driving circuit is used to drive the sub-pixel display.

[0051] like Figures 1 to 5 As shown, the light-emitting surface of the display panel 30 faces the side of the light-shielding layer 20. The light-shielding layer 20 can be set to correspond to the non-display area NA. The light-shielding layer 20 can block the metal traces of the non-display area NA, etc., to prevent reflections from the metal traces, etc., from affecting the appearance of the display module 1. The light-shielding layer 20 does not cover the display area AA, thereby preventing the light-shielding layer 20 from blocking the display screen of the display area AA.

[0052] like Figure 1 As shown, Figure 1 The positions of the light-transmitting area 21 and the first hole 22 in the display module 1 are shown. It should be noted that, viewed from the top view of the display module 1, the first hole 22 is blocked by the cover plate body 10. The light-transmitting area 21 corresponds to the non-display area NA of the display panel 30. The light-transmitting area 21 can correspond to the placement of sensors, etc. The sensor can be set on the side of the display panel 30 away from the cover plate body 10, and the sensor can receive the light transmitted through the light-transmitting area 21 to realize the sensing function.

[0053] The light transmittance of the light-transmitting area 21 can be set according to the light-sensing requirements of the sensor. The light transmittance of the light-transmitting area 21 refers to the overall light transmittance of the display module 1 in the light-transmitting area 21, that is, the ratio of the brightness of the light incident on the sensor to the brightness of the light on the side of the cover plate body 10 away from the sensor. The light transmittance of the light-transmitting area 21 can range from 5% to 20%. For example, the light transmittance of the light-transmitting area 21 can be 5%, 6%, 7%, 8%, 9%, 10%, 11%, 12%, 13%, 14%, 15%, 16%, 17%, 18%, 19%, 20%, etc.

[0054] The light-shielding layer 20 is made of a material with a light-shielding effect; for example, it can be black ink, but is not limited to this. The light transmittance of the light-shielding layer 20 in the light-transmitting area 21 is greater than that in other areas. For example, the light transmittance of the light-shielding layer 20 in the light-transmitting area 21 ranges from 5% to 25%. The light transmittance of other areas of the light-shielding layer 20, excluding the light-transmitting area 21, can be less than 5%. The lower the light transmittance of other areas of the light-shielding layer 20, the better the light-shielding effect. Optionally, the light transmittance of other areas of the light-shielding layer 20 can be less than 2%. The light-shielding layer 20 can be formed on one side surface of the cover plate body 10 using a printing process, but is not limited to this.

[0055] Optionally, the thickness of the light-shielding layer 20 is from 2 micrometers to 6 micrometers. For example, the thickness of the light-shielding layer 20 is 2 micrometers, 2.5 micrometers, 3 micrometers, 3.5 micrometers, 4 micrometers, 4.5 micrometers, 5 micrometers, 5.5 micrometers, 6 micrometers, etc.

[0056] It should be noted that there is no boundary between the light-transmitting area 21 and other areas of the light-blocking layer 20. The material of the light-transmitting area 21 and the material of the non-light-transmitting area 21 of the light-blocking layer 20 are the same material, and there is no thickness difference between the two areas, so no obvious marks will be produced.

[0057] In the light-shielding layer 20, the light transmittance of the light-transmitting area 21 is greater than that of the non-light-transmitting area 21. The increased light transmittance of the light-transmitting area 21 is achieved by providing multiple first holes 22 within it. Each first hole 22 penetrates the light-shielding layer 20 along its thickness direction. Since there is no light-shielding material within the first hole 22, its light transmittance is greater than that of areas where light-shielding material is present. By providing multiple first holes 22, the overall light transmittance can meet the usage requirements. The ratio of the total area of ​​the multiple first holes 22 corresponding to a light-transmitting area 21 to the area of ​​that light-transmitting area 21 can be from 0.05 to 0.2. When the ratio of the total area of ​​the first holes 22 to the area of ​​the light-transmitting area 21 increases, the light transmittance of the light-transmitting area 21 increases.

[0058] The area of ​​the light-transmitting area 21 can be set according to the area of ​​the photosensitive surface of the corresponding sensor. The area of ​​the light-transmitting area 21 can be greater than or equal to the area of ​​the photosensitive surface of the sensor. The light-transmitting area 21 is set to correspond to the non-display area NA of the display panel 30, which means that the light-transmitting area 21 does not exceed the range of the non-display area NA.

[0059] In some embodiments, such as Figure 1 As shown, the display module 1 has a light-transmitting area 21.

[0060] In some embodiments, the display module 1 is provided with multiple light-transmitting areas 21. The light transmittance of each light-transmitting area 21 can be adjusted according to the photosensitivity of the corresponding sensor, that is, the multiple light-transmitting areas 21 can have different light transmittances. In related technologies, light-transmitting areas 21 with different light transmittances use different light-transmitting inks, and different light-transmitting inks have color differences in appearance, which will lead to inconsistencies in the appearance of the display module 1. In this application, the material of the light-shielding layer 20 of the light-transmitting area 21 is the same as the material of the light-shielding layer 20 outside the light-transmitting area 21. By adjusting the opening area of ​​the first hole 22, the light transmittance of different light-transmitting areas 21 is adjusted, thereby avoiding color differences in the appearance of the display module 1.

[0061] Optionally, such as Figures 2 to 5 As shown, the display module 1 also includes a first functional layer 40 that is disposed on the side of the display panel 30 away from the cover plate body 10; wherein, the first functional layer 40 is provided with a second hole 41 corresponding to the light-transmitting area 21, each first hole 22 is located in the second hole 41, and the depth of the second hole 41 is less than or equal to the thickness of the first functional layer 40.

[0062] like Figures 2 to 5 As shown, the first functional layer 40 is disposed on the side of the display panel 30 opposite to the light-emitting surface of the display panel 30. The first functional layer 40 is in contact with the display panel 30. The first functional layer 40 can be a single-layer film or a stack of multiple film layers. The first functional layer 40 can be a stack of one or more flexible materials and rigid materials. Flexible materials can be polyethylene terephthalate, polyimide, polycarbonate, carbon fiber, etc. Rigid materials can be stainless steel, titanium, aluminum, copper, etc. The first functional layer 40 is used to support and protect the display panel 30, making the back of the display panel 30 less susceptible to impact damage. The side of the first functional layer 40 near the display panel 30 may include an adhesive layer (not shown in the figure), which is used to bond the first functional layer 40 to the surface of the display panel 30. When the first functional layer 40 is a stack of multiple film layers, an adhesive layer (not shown in the figure) can also be disposed between two adjacent film layers.

[0063] A second hole 41 may be provided on the side of the first functional layer 40 opposite to the light-emitting surface of the display panel 30. The second hole 41 is provided corresponding to the light-transmitting area 21, and the first holes 22 are all located within the second hole 41. The second hole 41 can be one or more holes corresponding to the light-transmitting area 21, and this application does not limit this. By providing the second hole 41 on the first functional layer 40, the light transmittance of the first functional layer 40 in the light-transmitting area 21 can be increased, thereby improving the light transmittance of the light-transmitting area 21 of the display module 1.

[0064] like Figures 2 to 5 As shown, the explanation will focus on the second hole 41 as an example. The depth of the second hole 41 can be less than or equal to the thickness of the second functional layer 50. This means that, as... Figure 2 As shown, when the depth of the second hole 41 is less than the thickness of the second functional layer 50, the second hole 41 does not completely penetrate the first functional layer 40; as Figures 3 to 5 As shown, when the depth of the second hole 41 is equal to the thickness of the second functional layer 50, the second hole 41 completely penetrates the first functional layer 40.

[0065] Optionally, such as Figures 3 to 5 As shown, the first functional layer 40 includes a stacked back plate layer 411 and a support layer 412. The support layer 412 is disposed on the side of the back plate layer 411 away from the cover plate body 10. The modulus of the support layer 412 is greater than that of the back plate layer 411. The depth of the second hole 41 is equal to the thickness of the first functional layer 40, and the opening area of ​​the second hole 41 on the back plate layer 411 is smaller than the opening area of ​​the second hole 41 on the support layer 412.

[0066] The material of the back panel layer 411 may include, but is not limited to, one or more of the following: silica, polyester resin, polyethylene, polypropylene, polystyrene, polylactic acid, polyethylene terephthalate, polyimide, or polyurethane. The back panel layer 411 can prevent the display panel 30 from being damaged by external forces and can block water and oxygen.

[0067] The modulus of the support layer 412 is greater than that of the back panel layer 411. The support layer 412 has a certain degree of rigidity, which can provide back support and protection for the display panel 30, making the back of the display panel 30 less susceptible to impact damage. The material of the support layer 412 can be metal, such as stainless steel, copper, aluminum, etc.

[0068] like Figures 3 to 5 As shown, the depth of the second hole 41 is equal to the thickness of the first functional layer 40, that is, the second hole 41 penetrates the support layer 412 and the back plate layer 411 along the thickness direction of the first functional layer 40.

[0069] Optionally, such as Figures 3 to 5As shown, the opening area of ​​the second hole 41 on the support layer 412 can be larger than the opening area of ​​the second hole 41 on the back plate layer 411, that is, the second hole 41 is a stepped hole. This allows the back plate layer 411 to cover the sidewall of the second hole 41 on the support layer 412, so that the back plate layer 411 provides support for the support layer 412 and prevents the sidewall of the second hole 41 on the support layer 412 from pressing against the display panel 30 and causing marks.

[0070] It should be understood that the depth of the second hole 41 can be set according to the light transmittance of the light-transmitting area 21. In order to increase the light transmittance of the light-transmitting area 21, the depth of the second hole 41 can be increased, that is, the second hole 41 penetrates more of the material of the first functional layer 40.

[0071] Optionally, such as Figure 4 and Figure 5 As shown, the display panel 30 is provided with a third hole 31 that communicates with the second hole 41, and the sidewall of the second hole 41 on the back panel layer 411 is flush with the sidewall of the third hole 31.

[0072] To further improve the light transmittance of the light-transmitting area 21, a third hole 31 can be provided on the display panel 30. The third hole 31 completely penetrates the display panel 30 along its thickness direction. Since the third hole 31 is located in the non-display area NA of the display panel 30, providing the third hole 31 will not affect the display image of the display panel 30.

[0073] In this application, "two holes connected" means that the two holes are not separated by any other membrane layer. For example, "the second hole 41 is connected to the third hole 31" means that the second hole 41 and the third hole 31 are not separated by any other membrane layer.

[0074] In this application, any hole can be created using a laser cutting process. To simplify the process, the sidewall of the second hole 41 can be flush with the sidewall of the third hole 31, thereby enabling the creation of openings in the first functional layer 40 and the display panel 30 in the same laser cutting process.

[0075] Optionally, the back panel 411 and the display panel 30 can be bonded together before the hole is drilled, so that the back panel 411 and the display panel 30 are drilled using the same process. The support layer 412 can be drilled using a different process, so that the second hole 41 forms holes with different opening areas on the support layer 412 and the back panel 411.

[0076] Optionally, such as Figure 4 As shown, there are multiple third holes 31, and each first hole 22 is located within a third hole 31. The opening area of ​​the third hole 31 is larger than the opening area of ​​the first hole 22.

[0077] There can be multiple third holes 31, with adjacent third holes 31 spaced apart. One third hole 31 corresponds to one first hole 22, and light can pass through the corresponding first hole 22 and third hole 31.

[0078] Optionally, such as Figure 4 As shown, the opening area of ​​the third hole 31 is larger than the opening area of ​​the first hole 22. For example, when the shape of the third hole 31 is the same as the shape of the first hole 22, the opening size of the third hole 31 is 0.1 mm to 0.5 mm larger than the opening size of the first hole 22 in the same direction. For example, the opening size of the third hole 31 is 0.1 mm, 0.2 mm, 0.3 mm, 0.4 mm, 0.5 mm, etc., larger than the opening size of the first hole 22.

[0079] A light-shielding layer 20 is typically formed on the cover plate body 10, and then the cover plate body 10 with the light-shielding layer 20 is bonded to the display panel 30. During the bonding process, alignment tolerances exist. To avoid misalignment between the third hole 31 and the first hole 22 due to bonding misalignment, which would affect the light transmittance of the light-transmitting area 21, the opening size of the third hole 31 can be larger than the opening size of the first hole 22. In this way, even with bonding misalignment, the first hole 22 can still be located within the third hole 31, reducing the impact of process tolerances on the light transmittance of the light-transmitting area 21.

[0080] In some embodiments, the light transmittance of the light-transmitting area 21 of the display module 1 can be further improved by increasing the opening area of ​​the third hole 31.

[0081] Optionally, such as Figure 4 and Figure 5 The display module 1 includes a second functional layer 50 that is disposed on the side of the display panel 30 near the cover body 10; wherein the second functional layer 50 is provided with a fourth hole 51 that communicates with the third hole 31, and the depth of the fourth hole 51 is less than or equal to the thickness of the second functional layer 50.

[0082] The second functional layer 50 is disposed on one side of the light-emitting surface of the display panel 30. The surface of the second functional layer 50 closest to the display panel 30 is in contact with the display panel 30, and the surface of the second functional layer 50 closest to the light-shielding layer 20 is in contact with the light-shielding layer 20. The second functional layer 50 can be a single-layer film or a stack of multiple film layers. The second functional layer 50 can protect the front of the display panel 30 from impact damage. The second functional layer 50 can also be used to reduce reflection of ambient light, etc. The second functional layer 50 can include one or more stacks of organic materials. The organic materials can be polyethylene terephthalate, polyimide, or polyurethane, etc. The side of the second functional layer 50 closest to the display panel 30 can include an adhesive layer (not shown in the figure), which is used to bond the second functional layer 50 to the surface of the display panel 30. When the second functional layer 50 is a stack of multiple film layers, an adhesive layer (not shown in the figure) can also be disposed between adjacent film layers.

[0083] Optionally, such as Figure 4 As shown, the depth of the fourth hole 51 is less than the thickness of the second functional layer 50; there are multiple fourth holes 51, and the sidewall of the fourth hole 51 is flush with the sidewall of the third hole 31. By setting the fourth hole 51 on the second functional layer 50, the light transmittance of the second functional layer 50 in the light-transmitting area 21 can be increased, thereby improving the light transmittance of the light-transmitting area 21 of the display module 1.

[0084] When the depth of the fourth hole 51 is less than the thickness of the second functional layer 50, the fourth hole 51 does not completely penetrate the second functional layer 50. The fourth hole 51 can communicate with the third hole 31, and the sidewall of the fourth hole 51 is flush with the sidewall of the third hole 31. With the above settings, openings in the second functional layer 50 and the display panel 30 can be achieved in the same laser cutting process.

[0085] Optionally, the number of fourth holes 51 is the same as the number of third holes 31. When the third hole 31 is a single hole, the fourth hole 51 is also a single hole; when the third hole 31 is multiple holes, the fourth hole 51 is also multiple holes, the same number as the third hole 31.

[0086] In some embodiments, when the fourth hole 51 is multiple holes, the opening area of ​​the fourth hole 51 can be increased to further improve the light transmittance of the light-transmitting area 21 of the display module 1.

[0087] Optionally, such as Figure 5 As shown, the depth of the fourth hole 51 is equal to the thickness of the second functional layer 50. The second functional layer 50 includes a stacked adhesive layer 511 and a polarizer 512. The polarizer 512 is located on the side of the adhesive layer 511 away from the cover plate body 10. The opening area of ​​the fourth hole 51 on the polarizer 512 is smaller than the opening area of ​​the fourth hole 51 on the adhesive layer 511.

[0088] The adhesive layer 511 can be made of a transparent adhesive layer, such as optically clear adhesive (OCA), but is not limited to this.

[0089] The polarizer 512 can reduce the reflection of ambient light by the display panel 30, thus improving the glare problem caused by the reflection of ambient light. The side of the polarizer 512 closest to the display panel 30 can be bonded to the display panel 30 with an adhesive layer.

[0090] Optionally, such as Figure 5 As shown, the opening area of ​​the fourth hole 51 on the polarizer 512 is smaller than the opening area of ​​the fourth hole 51 on the adhesive layer 511, thereby preventing the adhesive layer 511 from extending beyond the sidewall of the polarizer 512 along the display plane. During the assembly and bonding process, if the adhesive layer 511 extends beyond the sidewall of the polarizer 512 along the display plane, the exposed adhesive layer 511 is prone to attracting foreign objects, which will affect the light transmittance of the light-transmitting area 21. Therefore, by making the opening area of ​​the fourth hole 51 on the polarizer 512 smaller than the opening area of ​​the fourth hole 51 on the adhesive layer 511, the risk of foreign objects attracting to the adhesive layer 511 can be reduced.

[0091] Optionally, such as Figures 6 to 8 As shown, the shape of the first hole 22 includes triangle, quadrilateral, and circle. The arrangement of the first holes 22 can be set as needed, and this application does not limit it. Multiple first holes 22 can be symmetrically arranged about the center line of the light-transmitting area 21, so as to make the light transmittance of the light-transmitting area 21 uniform.

[0092] like Figure 6 As shown, the first hole 22 is circular in shape. Multiple first holes 22 may be distributed circumferentially along the center of the light-transmitting area 21, but are not limited to this.

[0093] like Figure 7 As shown, the first hole 22 is triangular in shape. Multiple first holes 22 may be symmetrically distributed about the center line of the light-transmitting area 21, but are not limited to this arrangement.

[0094] like Figure 8 As shown, the first hole 22 is quadrilateral in shape. Multiple first holes 22 can be arranged in a straight line, but are not limited to this.

[0095] In the embodiments of this application, in order to increase the amount of light passing through the light-transmitting area 21, openings can be made in each film layer of the first functional layer 40 and the second functional layer 50. The number and size of the openings can be set according to the light transmittance of each film layer in the first functional layer 40 and the second functional layer 50, as well as the photosensitivity requirements of the sensor. The larger the ratio of the area of ​​the opening to the area of ​​the light-transmitting area 21, the greater the light transmittance of the light-transmitting area 21 of the display module 1.

[0096] Optionally, in the light-transmitting area 21 of the display module 1, the light transmittance of the light-shielding layer 20 in the light-transmitting area 21 is 5% to 25%, and the light transmittance of other film layers besides the light-shielding layer 20 is 50% to 90%, so that the overall light transmittance of the light-transmitting area 21 of the display module 1 meets the requirement of 5% to 20%.

[0097] According to the second aspect of this application, such as Figure 9 As shown, a display terminal 2 is provided, including the display module 1 described above.

[0098] In this embodiment, as Figure 9 As shown, the display terminal 2 includes a display module 1 and a terminal body 3, which are combined into one unit.

[0099] The light transmittance of the light-transmitting area 21 of the display module 1 ranges from 5% to 20%, thereby meeting the light-sensing requirements of the sensor.

[0100] In this embodiment, the display terminal 2 can be any product or component with display function, such as a mobile phone, tablet computer, television, monitor, laptop computer, digital photo frame, or navigator.
