Description

Technical Field

[0001] This utility model relates to the field of home appliance display panel technology, specifically to an anti-cross-light home appliance display panel. Background Technology

[0002] Home appliance display panels are used as decorative and functional control panels for home appliances, and are widely used in air conditioners, washing machines, refrigerators, etc. Existing technologies mostly adopt the traditional in-mold injection molding (IDM) process, which prints all characters on a single film on the front and uses a lightbox frame structure to achieve display. However, due to factors such as the thickness of the injection-molded substrate, the distance between the characters and the light source, the refraction interference of the transparent substrate, and the insufficient spacing between adjacent characters, light is easily scattered and interfered with, making it difficult to meet the requirements of anti-crosslighting and display clarity in high-demand scenarios. Therefore, we propose an anti-crosslighting home appliance display panel. Utility Model Content

A sliding rod is slidably connected inside the guide rail, and a scraper is slidably connected inside the sliding rod. A spring assembly is fixedly connected to the inner wall of the sliding rod, and the other end of the spring assembly is fixedly connected to the scraper.

[0007] The fixed frame has an auxiliary mechanism on the side away from the fixed block. The auxiliary mechanism includes a groove on the inner wall of the fixed frame, a spring is fixedly connected in the groove, and a fixed plate is fixedly connected to the other end of the spring.

[0008] The scraper is made of food-grade silicone, and the end of the scraper that contacts the diaphragm has a rounded design.

[0009] The auxiliary mechanism has multiple components evenly distributed along the inner wall of the fixed frame.

[0010] The fixing plate has a cushioning sponge on the side closest to the diaphragm.

[0011] This utility model has at least the following beneficial effects: In use, this utility model effectively avoids light refraction, scattering, and interference by setting two layers of films that fit tightly together and matching characters, thereby improving display stability and clarity and adapting to various lighting environments.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Example 1 Please see Figures 1 to 7 This utility model provides a technical solution: an anti-crosslight display panel for home appliances, comprising: a display panel body 1, a first film 2 fixedly connected inside the display panel body 1, a second film 3 disposed on the first film 2, the second film 3 covering the surface of the first film 2, characters disposed on the first film 2 and the second film 3, the characters on the first film 2 being invisible and not displayed in the absence of backlight, and the characters on the second film 3 being clearly displayed in all situations, the two films being tightly bonded to effectively prevent light from being refracted or scattered between the two films, the character design of the first film 2 making the actual position of the characters closer to the light source, and the light source illumination more direct, and at the same time, through the cooperation of the characters on the two films, effectively preventing light from different areas from interfering with each other, and improving display stability.

[0016] A fixing frame 4 is fixedly connected to the main body 1 of the display panel. The fixing frame 4 is equipped with a fixing mechanism 5 for fixing the second diaphragm 3. The second diaphragm 3 can be fixed above the first diaphragm 2 through the fixing mechanism 5. When the second diaphragm 3 is covered by oil or scratches due to long-term use, affecting the display effect, the user can quickly replace and attach the severely worn second diaphragm 3 by himself through the fixing mechanism 5. The whole replacement process is simple and convenient, which can effectively shorten the maintenance time, thereby ensuring the durability of the anti-light crossing effect and the clarity of the display.

[0017] The fixing mechanism 5 includes a fixing block 51 fixedly connected to the fixing frame 4, and a placement groove 52 is provided on the fixing block 51. It also includes a guide rail 53, which is provided on both sides of the inner wall of the fixing frame 4. A sliding rod 54 is slidably connected in the guide rail 53, and a scraper 55 is slidably connected in the sliding rod 54. A spring assembly 56 is fixedly connected to the inner wall of the sliding rod 54, and the other end of the spring assembly 56 is fixedly connected to the scraper 55. The size of the placement groove 52 matches the second diaphragm 3. When replacing, the edge of the second diaphragm 3 can be embedded in the placement groove 52 to achieve initial positioning. The sliding rod 54 can slide freely along the length of the guide rail 53, thereby driving the scraper 55 to slide on the second diaphragm 3. Under the elastic force of the spring assembly 56, the scraper 55 can always be kept in contact with the surface of the second diaphragm 3.

[0018] In use, the sliding rod 54 slides above the fixed block 51. At this time, the severely worn second diaphragm 3 can be removed, and the new second diaphragm 3 can be inserted into the placement slot 52 to achieve initial positioning of one end of the second diaphragm 3. At this time, by sliding the sliding rod 54, the scraper 55 is made to adhere to the second diaphragm 3 and slide along the guide rail 53, which can quickly remove air bubbles between the first diaphragm 2 and the second diaphragm 3. When it slides to the end, the sliding rod 54 descends along the guide rail 53. Under the elastic force of the spring assembly 56, the scraper 55 applies pressure to the other end of the second diaphragm 3 to ensure the adhesion between the diaphragms and prevent up and down movement.

[0019] An auxiliary mechanism 6 is provided on the side of the fixed frame 4 away from the fixed block 51. The auxiliary mechanism 6 includes a groove 61 opened on the inner wall of the fixed frame 4. A spring 62 is fixedly connected in the groove 61. A fixed plate 63 is fixedly connected to the other end of the spring 62. When in use, after the second diaphragm 3 is installed in place, the fixed plate 63 presses tightly against the edge of the second diaphragm 3 under the elastic force of the spring 62, and cooperates with the placement groove 52 on the fixed block 51 to form a two-way fixation, further improving the installation stability of the second diaphragm 3.

[0020] The scraper 55 is made of food-grade silicone. The end of the scraper 55 that contacts the film is rounded. Silicone has good flexibility and wear resistance, and will not cause scratches or chemical corrosion to the surface of the second film 3. The rounded design avoids damage to the film from sharp edges, ensuring film adhesion while protecting the display performance of the film.

[0021] The auxiliary mechanism 6 is provided with multiple auxiliary mechanisms evenly distributed along the inner wall of the fixed frame 4. The multiple auxiliary mechanisms 6 are evenly distributed along the length direction of the inner wall of the fixed frame 4, and the distance between two adjacent auxiliary mechanisms 6 is equal, so that the fixing force on the edge of the second diaphragm 3 is evenly distributed, preventing the diaphragm from deforming due to excessive local force, causing the diaphragms to separate and thus affecting the display effect and anti-light crosstalk performance.

[0022] Example 2 In this second embodiment, the other structures remain unchanged. The difference from the first embodiment is that the fixing plate 63 is provided with a buffer sponge 7 on the side near the diaphragm. The buffer sponge 7 has good elasticity and buffering performance. When the fixing plate 63 abuts against the edge of the second diaphragm 3, the buffer sponge 7 can reduce the squeezing damage to the edge of the diaphragm and at the same time enhance the friction between the two, further preventing the diaphragm from shifting.
