[0002] With the diversified development of the commercial refrigeration industry, the demand for and experience of refrigeration equipment at the end-user level is gradually increasing. For commercial refrigeration equipment, in addition to meeting the cooling needs of the equipment, it is also particularly important to enhance the commercial value of display cabinets and promote the brand development and construction of major customers.

[0003] Current display cabinets typically use light box stickers to promote customer brands, using LED lights and other light sources to illuminate billboards to achieve the desired advertising effect. However, using external stickers for promotion requires placing other equipment, such as power supplies, in the light box's location, which often results in a significant waste of space. Furthermore, light boxes are susceptible to dust and are difficult to clean in outdoor environments, weakening the promotional effect. Existing display cabinets also use injection-molded luminous characters or billboards made of glass panels printed with luminous ink and light beads within glass doors for promotional purposes. However, this method offers limited effectiveness and cannot be modified after the product is manufactured. Utility Model Content

[0004] In order to address the deficiencies in the prior art, the present invention provides a light-emitting device and a refrigerated display cabinet with a transparent display effect, which can reduce the waste of space resources and prevent dust from falling on the light box, weakening the promotional effect. At the same time, the display driver module in the present invention controls the different brightness and darkness states of the lamp bead matrix, solving the problem of fixed shape and unadjustable advertising content caused by the use of injection-molded luminous characters or printed luminous ink glass plates.

[0018] To make the purpose, technical solutions, and advantages of the present invention more clear, the technical solutions of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. The embodiments described in this application are only some embodiments of the present invention, not all embodiments. Based on the spirit of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0019] Example 1:

[0020] The utility model provides a light-emitting device with a transparent display effect. Figure 1 This invention relates to the application of a light-emitting device with a transparent display effect in a refrigerated display cabinet. The light-emitting device with a transparent display effect includes a display module 4, a display driver module 5, and a control module 2. The control module 2 is electrically connected to the display driver module 5. The control module 2 converts a preset image or text content into a corresponding display format and outputs a display format command to the display driver module 5. The display driver module 5 interprets the display format command output by the control module 2 and controls the lighting of corresponding lamps in the lamp matrix of the display module 4.

[0021] The display module 4 is composed of a substrate, a miniLED lamp matrix, and wires. The lamp matrix is composed of a number of miniLED lamps, which are mounted on the substrate. Printed wires on the substrate connect the miniLED lamps in parallel or series, and the lamp matrix is connected to the display driver module 5 via wires. The miniLED lamp matrix can be arranged on various substrates, including but not limited to flexible conductive films, glass substrates, and other transparent / translucent substrate materials.

[0022] The spacing between adjacent miniLED beads is greater than the size of the miniLED beads. Because the size of a single miniLED chip is only about 1 / 10 of that of a regular LED chip, adjusting the spacing d between adjacent miniLED beads allows each bead to be closer to the size of a pixel, achieving high contrast with the dark areas at the miniLED bead spacing. Furthermore, a larger spacing d between miniLED beads enables a visually transparent display. The size of the display module 4 can be adjusted based on actual usage requirements. The number of driver chips in the display driver module 5 is adjusted accordingly based on the number and partitioning of miniLED beads at different sizes.

[0023] The driver chip in Display Driver Module 5 reads the position information of the miniLED beads to be illuminated from the control signal and controls the on / off of each miniLED in the matrix. It also illuminates the beads in a predetermined sequence according to a pre-set scanning pattern to display the programmed graphics or text. The display driver module 5's instantly adjustable drive output control allows for rapid refresh of the matrix's display content, achieving dynamic content display effects.

[0024] On the other hand, the present invention provides an optional embodiment, a light-emitting device with a transparent display effect further includes a communication module, and the communication module transmits data with the control module 2 through the data transmission module 1 to achieve remote or local adjustment of the display content of the display module 4. The data transmission module 1 can be selected as a WIFI module or a 4G-CAT1 communication module. The WIFI module can be directly connected to a terminal device such as a mobile phone through WIFI, and data communication is performed through a point-to-point connection between the WIFI module and the terminal, and the target display text or pattern is transmitted from the terminal to the control module 2 to change the display content of the display module 4. The 4G-CAT1 communication module can be connected to the network through the operator's network access point, and establish communication with the remote server through the corresponding API interface. The server can remotely send the display content of the display module 4 through the network connection, and the data transmission module 1 receives the display content data transmitted by the server and forwards it to the control module 2, which controls the display driver module 5 to adjust the display content of the display module 4.

[0025] Example 2:

[0026] like Figure 1 As shown, the utility model provides a refrigerated display cabinet, comprising a cabinet, a door, and a light-emitting device with a transparent display effect in Example 1, wherein a control module 2 is arranged on the top of the cabinet, the door comprises double-layer glass and a door frame, and the double-layer glass is surrounded by a door frame;

[0027] The display module 4 and display driver module 5 are placed within the double-layer glass, utilizing the low temperature inside the refrigerated display cabinet to mitigate heating issues caused by the miniLED lamp beads. The display driver module 5 is located above the display module 4. A silk-screen ink layer 6 is printed on the outer glass of the door, corresponding to the display driver module 5, to cover the display driver module 5.

[0028] The display driving module 5 is arranged inside the door frame, and a silk-screen ink layer 6 is provided on the outer surface of the display driving module 5 .

[0029] LED vertical lights 3 are installed along the inner side of the door frame along the longitudinal direction. These vertical lights are angled toward the interior of the cabinet to illuminate the merchandise on display. The addition of these LED vertical lights increases the light intensity inside the cabinet compared to the light intensity outside the refrigerated display case, enhancing the transparency of the display module 4 area. Furthermore, the larger miniLED bead spacing d enhances the penetration of light from within the cabinet into the display module 4, further enhancing the transparent display effect.

[0030] In some embodiments, as Figure 2 As shown, some refrigerated display cabinets have low demand for advertising, the display module 4 is small in size, the number of driver chips corresponding to the display driver module 5 is small, the display driver module 5 can be installed in the door frame, and the silk screen ink layer 6 is printed on the outer surface of the door frame.

[0031] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, ordinary technicians in the relevant field should understand that the specific implementation methods of the present invention can still be modified or replaced by equivalents, and any modifications or equivalent replacements that do not depart from the spirit and scope of the present invention should be included in the scope of protection of the claims of the present invention.
