Technical Field

[0001] This application relates to the field of displays, and more particularly to a light strip and a display device. Background Technology

[0002] As people's living standards continue to improve, LED LCD monitors are increasingly used in daily office work, computer games, and other applications. Most of these LED LCD monitors use side-lit LED strips for backlighting, which, together with a light guide plate, convert line light sources into surface light sources.

[0003] Traditional light strips, due to their bracket and light-emitting surface design, tend to cause light to scatter in all directions during propagation, forming a large divergence angle, which in turn poses a risk of light leakage.

[0004] Therefore, how to improve the light leakage phenomenon of light strips has become an urgent problem to be solved in this field. Utility Model Content

[0005] This application discloses a light strip and a display device, the purpose of which is to improve the light leakage problem of the light strip.

[0006] This application discloses a light strip, which includes a substrate and a plurality of light-emitting units disposed on the substrate. The plurality of light-emitting units are arranged along the extension direction of the substrate. A dam structure is also disposed on the substrate. The dam structure is disposed around at least a portion of the light-emitting units and at least a portion of the light-emitting units are surrounded within the space enclosed by the dam structure. The dam structure is used to block the light emitted by the light-emitting units.

[0012] Optionally, the plurality of light-emitting units are arranged in a single row, and the plurality of light-emitting units include adjacent red light-emitting units, green light-emitting units, and blue light-emitting units. Each adjacent red light-emitting unit, green light-emitting unit, and blue light-emitting unit forms a light-emitting unit group, and the plurality of light-emitting units are divided into multiple groups of light-emitting unit groups. The arrangement order of the red light-emitting units, green light-emitting units, and blue light-emitting units in two adjacent groups is different. Alternatively, the plurality of light-emitting units are arranged in multiple rows on the substrate, and each row of light-emitting units includes adjacent red light-emitting units, green light-emitting units, and blue light-emitting units. The arrangement order of the red light-emitting units, green light-emitting units, and blue light-emitting units in two adjacent rows of light-emitting units is different.

Detailed Implementation

[0028] The present application will now be described in detail with reference to the accompanying drawings and optional embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0029] Figure 1 This is a partial schematic diagram of the first embodiment of the light strip of this application, as shown below. Figure 1 As shown in the figure, this application discloses a light strip 100, which includes a substrate 110 and a plurality of light-emitting units 120 disposed on the substrate 110. The plurality of light-emitting units 120 are arranged along the extension direction of the substrate 110. A dam structure 130 is also disposed on the substrate 110. The dam structure 130 is disposed around at least a portion of the light-emitting units 120 and at least a portion of the light-emitting units 120 are surrounded within the space enclosed by the dam structure 130. The dam structure 130 is used to block some of the light emitted by the light-emitting units 120.

[0030] This application improves upon the conventional light strip 100 by additionally providing a dam structure 130 on the substrate 110 of the light strip 100. The dam structure 130 surrounds at least a portion of the light-emitting units 120, so that the large-angle divergent light emitted by some of the light-emitting units 120 can be blocked by the dam structure 130, thereby preventing the light from diverging in all directions and thus improving the light leakage problem of the light strip 100 to a certain extent.

[0031] It should be noted that in this application, the dam structure 130 acts as a "barrier" to the large-angle divergent light emitted by the light-emitting unit 120, effectively shielding the large-angle divergent light of the light-emitting unit 120, thus making it difficult for the light of the light-emitting unit 120 to spread to all sides, effectively improving the light leakage problem of the light strip 100. When the light strip 100 is a side-entry light strip 100 and is installed in the display device 10, it can effectively prevent light leakage from the side light strip 100 position when viewing the screen directly, thus preventing the screen from becoming colorless or uneven in color.

[0032] In this application, the dam structure 130 can be made of a white adhesive material. The solvent component of the white adhesive material mainly includes silicone resin, and the solute component mainly includes titanium dioxide. In the process of making the dam structure 130, after the white adhesive material is coated, it can be baked and cured in a tunnel oven or oven to form the white dam structure 130. The dam structure 130 not only acts as a retaining wall to block the light emitted by the light-emitting unit 120 from the light guide plate to eliminate the phenomenon of uneven color, but also improves the overall structural strength of the light strip 100 and extends the service life of the light strip 100.

[0033] Specifically, the height of the dam structure 130 is greater than or equal to the height of the light-emitting unit 120.

[0034] In this application, when the height of the dam structure 130 is equal to the height of the light-emitting unit 120, the large-angle divergent light emitted by the light-emitting unit 120 can be blocked by the dam structure 130 to a certain extent, thereby improving the light leakage problem of the light strip 100.

[0035] When the height of the dam structure 130 is higher than the height of the light-emitting unit 120, the dam structure 130 can block most of the large-angle divergent light emitted by the light-emitting unit 120, thereby further improving the light leakage problem of the light strip 100.

[0036] In addition, since the height of the dam structure 130 is greater than the height of the light-emitting unit 120, the dam structure 130 can also block external dust, moisture or mechanical impact from directly contacting the surface of the light-emitting unit 120, which is beneficial to extending the service life of the light-emitting unit 120, and thus extending the service life of the light strip 100.

[0037] In theory, the height of the dam structure 130 is high enough to completely block the light emitted by the light-emitting unit 120 and prevent the light from spilling out in unwanted directions. However, considering that there are certain requirements for the structure and size of the light strip 100 in actual products, the height of the dam structure 130 can be designed according to the actual needs of the light strip 100 in actual products.

[0038] Furthermore, it should be noted that, since the light-emitting units 120 on the light strip 100, which emit large-angle divergent light that is prone to causing light leakage, are mainly concentrated near the edge of the light strip 100, when there are multiple rows and columns of light-emitting units 120 on the light strip 100, the dam structure 130 can be used to enclose some of the light-emitting units 120 located at the edge of the substrate 110, while leaving some of the light-emitting units 120 located in the middle of the substrate 110 unused. This can effectively improve the light leakage problem of the light strip 100 and save the use of the dam structure 130, thereby saving materials and reducing costs.

[0039] Figure 2 This is a partial schematic diagram of the second embodiment of the light strip of this application, as shown below. Figure 2 As shown, at least three light-emitting units 150 are grouped into a light-emitting group 140, and a dam structure 130 is provided around each light-emitting group 140.

[0040] The difference between this embodiment and the previous embodiment is that in this embodiment, at least three of the multiple light-emitting units 120 are divided into a light-emitting group 140. This is because the multiple light-emitting units 120 generally include a blue light-emitting unit 151, a green light-emitting unit 152, and a red light-emitting unit 153. Therefore, dividing at least three consecutive light-emitting units 120 of different colors into a light-emitting group 140 allows a light-emitting group 140 to achieve RGB color display, which does not affect the normal display effect of the light strip 100.

[0041] Each light-emitting group 140 has an independent dam structure 130. The dam structure 130 can effectively block the light emitted by the light-emitting unit 120 in the light-emitting group 140, avoid light interference between different light-emitting groups 140, and thus improve the color display purity of the light strip 100.

[0042] In addition, the dam structure 130 surrounds each light-emitting group 140, which can concentrate the light in the specific area where the light-emitting group 140 is located, reducing the waste of light. When multiple dam structures 130 surround each light-emitting group 140 respectively, the light distribution of each light-emitting group 140 can be more concentrated, which is conducive to improving the light utilization efficiency of the light strip 100.

[0043] Figure 3This is a partial schematic diagram of the third embodiment of the light strip of this application, as shown below. Figure 3 As shown, the dam structure 130 surrounds all the light-emitting units 120 on the substrate 110 and is set at the edge of the substrate 110.

[0044] The difference between this embodiment and the previous embodiment is that in this embodiment, the dam structure 130 is disposed at the edge of the substrate 110. The dam structure 130 surrounds all the light-emitting units 120 on the substrate 110 from the edge of the substrate 110, and forms a complete frame structure around the substrate 110. On the one hand, it can protect all the light-emitting units 120, preventing external dust, moisture or other contaminants from entering the interior of the light strip 100, while reducing the impact of mechanical impact on the light-emitting units 120 and improving the reliability of the light strip 100. On the other hand, the dam structure 130 around the edge of the substrate 110 can block the large-angle divergent light emitted by the light-emitting units 120 that are close to the edge of the substrate 110, thereby improving the light leakage phenomenon of the light strip 100.

[0045] Figure 4 This is a partial schematic diagram of the fourth embodiment of the light strip of this application, as shown below. Figure 4 As shown, an encapsulation layer 160 is provided inside the dam structure 130, and the encapsulation layer 160 covers multiple light-emitting units 120.

[0046] The difference between this embodiment and the previous embodiment is that, in this embodiment, while a dam structure 130 is provided around the substrate 110, an encapsulation layer 160 is filled in the space enclosed by the dam structure 130, and the encapsulation layer 160 is used to cover the multiple light-emitting units 120.

[0047] In the actual manufacturing process of the encapsulation layer 160, after the white adhesive material is coated and cured to form the dam structure 130, a light-transmitting encapsulation adhesive is applied to the entire surface of the area where the light-emitting unit 120 and the driving chip 122 are located and the enclosed area enclosed by the dam structure 130 using a dispensing machine. After the light-transmitting adhesive is encapsulated, it is baked and cured in a tunnel oven or oven to form the encapsulation layer 160.

[0048] The light-transmitting encapsulation layer 160 can change the light emission angle of the light-emitting chip 121, thereby achieving uniform light mixing. At the same time, it can also protect the light-emitting unit 120 from corrosion by moisture and corrosive gases in the environment, which helps to extend the service life of the light strip 100.

[0049] In addition, when the light-transmitting encapsulating adhesive is applied, the dam structure 130 can prevent the light-transmitting encapsulating adhesive from overflowing, making it easier for the light-transmitting encapsulating adhesive to cure and form without causing pollution to the external environment or other parts of the substrate 110.

[0050] Figure 5 This is a top view schematic diagram of a single-row arrangement of multiple light-emitting units in the fifth embodiment of the light strip of this application. Figure 6 This is a top view schematic diagram of multiple light-emitting units arranged in multiple rows in the fifth embodiment of the light strip of this application, as shown below. Figure 5 and Figure 6 As shown, multiple light-emitting units 120 are arranged in a single row or multiple rows on the substrate 110.

[0051] This embodiment designs the arrangement of multiple light-emitting units 120. Multiple light-emitting chips 121 can be mass-transferred and soldered onto the pads of the substrate 110 of the light strip 100 using solder paste. The light-emitting chips 121 can be arranged in a single row or multiple rows on the substrate 110.

[0052] When multiple light-emitting units 120 are arranged in a single row on the substrate 110, the multiple light-emitting units 120 are arranged along the extension direction of the substrate 110. Since all the light-emitting units 120 are arranged on the same straight line, the circuit layout on the lamp strip 100 can be relatively simple, and it is easy to control the direction and distribution of the light emitted by the light-emitting units 120.

[0053] When multiple light-emitting units 120 are arranged in multiple rows on the substrate 110, the multiple light-emitting units 120 can be arranged in an array on the substrate 110, or the light-emitting units 120 in two adjacent rows can be arranged in a staggered manner on the substrate 110. The arrangement method is not limited and can be freely set according to the actual needs of the product.

[0054] When multiple light-emitting units 120 are arranged in multiple rows on the substrate 110, the light strip 100 can obtain a larger and wider illumination range and improve the light intensity of the light strip 100, which is beneficial to improving the optical performance of the light strip 100.

[0055] Specifically, multiple light-emitting units 120 are arranged in a single row. Each light-emitting unit 120 includes adjacent red light-emitting units 153, green light-emitting units 152, and blue light-emitting units 151. Each adjacent red light-emitting unit 153, green light-emitting unit 152, and blue light-emitting unit 151 forms a light-emitting unit group 150. The multiple light-emitting units 120 are divided into multiple light-emitting unit groups 150. The arrangement order of the red light-emitting units 153, green light-emitting units 152, and blue light-emitting units 151 in two adjacent light-emitting unit groups 150 is different. Alternatively, multiple light-emitting units 120 are arranged in multiple rows on the substrate 110. Each row of light-emitting units 120 includes adjacent red light-emitting units 153, green light-emitting units 152, and blue light-emitting units 151. The arrangement order of the red light-emitting units 153, green light-emitting units 152, and blue light-emitting units 151 in two adjacent rows of light-emitting units 120 is different.

[0056] For example, when multiple light-emitting units 120 are arranged in a single row on the substrate 110, all the light-emitting units 120 are arranged in a straight line on the substrate 110. In the multiple light-emitting unit groups 150, the three light-emitting units 120 in the first light-emitting unit group 150 are arranged in order as red light-emitting unit 153, green light-emitting unit 152, and blue light-emitting unit 151 (RGB arrangement); the three light-emitting units 120 in the second light-emitting unit group 150 are arranged in order as blue light-emitting unit 151, red light-emitting unit 153, and green light-emitting unit 152 (BRG arrangement); the three light-emitting units 120 in the third light-emitting unit group 150 are arranged in order as green light-emitting unit 152, blue light-emitting unit 151, and red light-emitting unit 153 (GBR arrangement), and so on. The order of each group of light-emitting units 120 is not limited. The above arrangement order is only for illustrative purposes. The specific arrangement order can be designed according to the actual needs of the product.

[0057] In a single-row arrangement, the light-emitting units 120 in different light-emitting unit groups 150 are arranged alternately in different orders, which reduces the light interference problem between adjacent light-emitting units 120 and thus improves the overall optical performance of the light strip 100.

[0058] Furthermore, for example, in a multi-row arrangement, the first row of three consecutive light-emitting units 120 are arranged alternately as red light-emitting unit 153, green light-emitting unit 152, and blue light-emitting unit 151; the second row of three consecutive light-emitting units 120 are arranged alternately as blue light-emitting unit 151, red light-emitting unit 153, and green light-emitting unit 152; the third row of three consecutive light-emitting units 120 are arranged alternately as green light-emitting unit 152, blue light-emitting unit 151, and red light-emitting unit 153, and so on. The order of the light-emitting units 120 in each row is not limited. The above arrangement order is only for illustrative purposes, and the specific arrangement order can be designed according to the actual needs of the product.

[0059] Among them, in two adjacent rows of light-emitting units 120, the three adjacent red light-emitting units 153, green light-emitting units 152 and blue light-emitting units 151 can also be arranged in a triangular pattern, so that a single row or every two rows can be evenly mixed into white light, and multiple rows can meet the high brightness requirements.

[0060] It should be noted that in this application, the number of light-emitting units 120 arranged in a single row or multiple rows is not limited and can be designed according to actual needs.

[0061] Figure 7 This is a partial top view of the sixth embodiment of the light strip of this application, as shown. Figure 7As shown, the light-emitting unit 120 includes a light-emitting chip 121 and a driver chip 122. The bare die driver chip 122 is attached to the light-emitting chip 121, and each driver chip 122 is used to independently control the corresponding light-emitting chip 121.

[0062] In this embodiment, a light-emitting chip 121 that can emit light independently is used instead of a traditional lamp bead using phosphor. A driver chip 122 with a bare die is attached to the light-emitting chip 121 that has been fixed on the substrate 110, so that an electrical connection is formed between the driver chip 122 and the light-emitting chip 121. The driver chip 122 is used to control the current passing through the light-emitting chip 121 to control the brightness of the chip, thereby realizing the individual control of each light-emitting chip 121.

[0063] Since the bare die driver chip 122 does not have a black plastic shell package, the size and thickness of the light-emitting unit 120 can be greatly reduced, thereby reducing the absorption of light and minimizing the impact of the package on the optical effect.

[0064] In addition, a coating can be applied to the outer surface of the driver chip 122 according to actual needs. The color, material, thickness and other parameters of the coating are not limited. The thickness is approximately in the micrometer range. Different coating colors, materials and thickness parameters have different physical effects on light absorption, reflection and refraction. In practice, the best parameter scheme should be selected to achieve the best optical effect.

[0065] It should be noted that in this embodiment, the multiple light-emitting chips 121 include red light chips, blue light chips and green light chips arranged in sequence. The main wavelength of the blue light chip is mainly 450nm or 457nm or above, and 457nm or above is used for physical low blue light function. The main wavelength of the green light chip is mainly around 525nm, and the main wavelength of the red light chip is mainly around 630nm. Specifically, the wavelength of the light-emitting chip 121 can be selected according to the actual needs of the product.

[0066] Figure 8 This is a partial top view of the seventh embodiment of the light strip of this application, as shown below. Figure 8 As shown, the light-emitting unit 120 includes a light-emitting chip 121, and a driving chip 122 is also disposed on the substrate 110. The driving chip 122 includes multiple signal channels, each signal channel is communicatively connected to at least one light-emitting chip 121, and each signal channel is used to control the signal transmission of at least one light-emitting chip 121.

[0067] The difference between this embodiment and the previous embodiment is that in this embodiment, a driver chip 122 controls multiple light-emitting chips 121 simultaneously. The number of channels of the driver chip 122 can be 4, 8, 12, 16, 32, 48 or other channels. Specifically, it can be determined according to the actual number of light-emitting chips 121 on the substrate 110. Each channel controls one or more light-emitting chips 121.

[0068] In this embodiment, using one driver chip 122 to control multiple light-emitting chips 121 simultaneously can effectively reduce the number of driver chips 122 mounted on the substrate 110. On the one hand, it can reduce the space occupied by the driver chip 122 on the substrate 110, thereby allowing the substrate 110 to have more space for the layout of other devices, which is beneficial to improving the space utilization of the substrate 110. On the other hand, by using one driver chip 122 to control multiple light-emitting chips 121 simultaneously, the number of driver chips 122 required can be reduced, thereby simplifying circuit design and reducing production costs.

[0069] Furthermore, when each channel can control one light-emitting chip 121 independently, the driver chip 122 can finely adjust each light-emitting chip 121, thereby achieving more uniform brightness output and better display effect. When each channel controls multiple light-emitting chips 121, it is beneficial to realize local dimming.

[0070] Figure 9 This is a schematic diagram of an embodiment of the display device of this application, as shown below. Figure 9 As shown in the figure, this application also discloses a display device 10, including a rear shell 200. The display device 10 also includes the aforementioned light strip 100, which is connected to the rear shell 200. By mounting the light strip 100 on the rear shell 200, different light effects can be provided for the display device 10, thereby enriching the functionality of the display device 10 and improving the user experience of the display device 10.

[0071] In traditional display devices 10, the design of the lamp's bracket and light-emitting surface causes the light to easily disperse in all directions during propagation, forming a large divergence angle, which in turn poses a risk of light leakage and affects the quality of the display device 10.

[0072] Based on the above problems, this application improves the lamp strip 100 in the conventional display device 10 by additionally providing a dam structure 130 on the substrate 110 of the lamp strip 100. The dam structure 130 surrounds at least part of the light-emitting units 120, so that the large-angle divergent light emitted by some of the light-emitting units 120 can be blocked by the dam structure 130, thereby preventing the light from diverging in all directions. This improves the light leakage problem of the lamp strip 100 to a certain extent and helps to improve the quality of the display device 10.

[0073] It should be noted that the inventive concept of this application can form many embodiments, but due to the limited space of the application documents, they cannot all be listed. Therefore, without conflict, the embodiments described above or the technical features can be arbitrarily combined to form new embodiments. After the embodiments or technical features are combined, the original technical effect will be enhanced.

[0074] The above description, in conjunction with specific optional embodiments, provides a further detailed explanation of this application and should not be construed as limiting the specific implementation of this application to these descriptions. For those skilled in the art, various simple deductions or substitutions can be made without departing from the concept of this application, and all such modifications or substitutions should be considered within the scope of protection of this application.
