Customized design and development of a 3.5-inch industrial-grade intercom display for a leading communication equipment manufacturer where the display was a high-brightness IPS fully laminated touch screen meeting IP67 protection standards. Additional features included the optimized shock-resistant frame and the anti-slip texture design, which were specially made for the unique requirements of the industry, thereby achieving stable operation when used in the harsh environment. The implementation of the intelligent light-sensing adjustment technology in the screen allows for automatic changes from day to night display modes based on the surrounding light, greatly improving the level of visibility and the overall efficiency of operations carried out outdoors.
Ourclient home brand has entrusted us with the development of a 2.8-inch minimalist clock display that is exclusively tailored for the house brand. It uses low power consumption technology, depolyed in an IPS full lamination and capable of supporting clear display from very wide viewing angles of up to 180°. We have based the bedroom usage scenarios as the primary one, in fact, and so, together with the ultra-thin borderless design and soft light guide structure, the final product will look absolutely in line with contemporary home style. To boost consumer comfort, a system for intelligent light sensing and automatically changing of display modes takes its place inside the screen, which leads to an automatic switch to the soft light mode during nighttime. This is a clear time display which does not interfere with the quality of one’s sleep.
Customized a 3.5-inch high-definition dashboard display for the client, Using high contrast IPS full lamination technology we were able to ensure that the display is seen clearly even in the presence of bright light. In compliance with automotive grade requirements we remodeled ultra narrow bezel and curved design so they perfectly complement the cockpit interior style. An intelligent light-sensing adjustment system has now been integrated into the screen which is capable of automatically adjusting brightness and color temperature with reference to the ambient light which significantly contributes to driving safety and visual comfort.
