Traditional small home appliances typically rely on physical buttons, lacking both a modern aesthetic and smart functionality. With the advancement of AI chips, consumer expectations for these products have evolved. Shenzhen Hongjia Technology has introduced a color LCD screen designed to facilitate this smart upgrade: a 3.99-inch (also referred to as 4.01-inch) bar-type display. Featuring a 400×960 resolution and In-Cell touch technology (primarily in portrait orientation), this screen represents a distinctive new form factor for human-machine interfaces in the small appliance sector. It leverages its unique aspect ratio, integrated touch capabilities, and high-fidelity display to replace traditional buttons or segment displays, thereby elevating the interactive experience and the product's overall premium feel.

The material design of underwater touch screens must focus on the three core goals of "waterproof and water-proof, corrosion-resistant and non-failure, and touch without misjudgment". The super-hydrophobic cover layer is used to reduce water interference, corrosion-resistant conductive materials replace traditional ITO, and precision sealing structures block water penetration. In addition, the appropriate material combination is selected in combination with scene requirements (such as consumer grade/industrial grade/deep sea grade).
