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.

Completely eliminating LCD light leakage is difficult (especially against a pure black background, where slight light leakage may occur at the edges). However, through optimized design (such as high-precision shading structures and zoned light control), the use of high-quality materials (such as low-defect light guide plates and high-light-shielding adhesive strips), and rigorous production processes (such as full lamination and precision assembly), light leakage can be significantly reduced.
