6.9-inch IPS In-Cell Touchscreen Display for Dual-86 Thermostats 720x1440 Resolution

      With the rapid advancement of smart home technology, customer expectations for smart "86-box" thermostats have reached new heights. Addressing common pain points—such as the limited information displayed on single 86-box screens, their small display areas, and a lack of fluid user experience—Shenzhen Hongjia Technology has successfully entered mass production with a display solution designed for dual-86 boxes. This brings us to the product we are introducing today: the HJ6900-01 model. Featuring a 6.9-inch TFT screen with a resolution of 720x1440 and a MIPI interface, this display effectively combines the visual real estate of two standard 86-box screens into one unit. This allows customers to utilize a single main controller and a single housing to achieve the functionality of two separate 86-box units—thereby significantly reducing costs and boosting profit margins. Manufactured using In-Cell technology, this 6.9-inch screen functions as a fully integrated touchscreen simply by attaching a cover glass; it offers exceptional cost-performance value, competitive unit pricing, and a straightforward debugging process. Furthermore, the screen features a slim profile, contributing to a thinner overall device design. It utilizes the ST7121P driver IC, which supports 2, 3, or 4-lane MIPI interfaces, making the touchscreen calibration process simple and efficient.

      This display boasts a contrast ratio of 1200:1, supports 16 million full colors, and delivers high brightness levels ranging from 600 to 1000 nits. Equipped with a wide-color-gamut LED backlight, it renders colors with true-to-life richness and vibrancy. The unit comes with an integrated black cover glass; when the screen is inactive, the entire front panel appears as a deep, uniform black, lending the finished device a premium, high-end aesthetic.
