With the lightweight and inclusive development trend of consumer electronics, home projectors have long lost the niche label of high-end audio-visual equipment, and have become essential digital products for ordinary families, renters, students and small office scenarios. Consumers’ purchasing logic has become increasingly rational. They no longer blindly pursue high-priced flagship models, but pay more attention to product practicality, convenience and cost performance, expecting to buy fully functional, easy-to-operate and stable projection equipment with a friendly budget. Therefore, low-price auto-focus projectors stand out in the market with core intelligent functions, completely breaking the long-standing industry stereotype that low-cost equipment comes with low-end configuration. Focusing on high-frequency pain points in daily use, this cost-effective intelligent projector takes full auto-focus as the core functional support, and is equipped with a full range of practical functions such as intelligent picture calibration, high-definition imaging, eye protection, intelligent interaction and long-lasting battery life. It delivers premium-level user experience at an affordable price, perfectly adapting to diverse daily scenarios including audio-visual entertainment, study and office work, and outdoor leisure, making it a mainstream preferred product in the entry-level projection market.

　　Auto-focus is the core and most differentiated flagship function of low-price auto-focus projectors, and also the key to completely upgrading the user experience of low-cost projectors. Traditional entry-level projectors generally adopt manual focusing mode. Every time users move the equipment, adjust the placement angle or change usage scenarios, they need to manually rotate the lens to fine-tune the focal length repeatedly, which is cumbersome and low in fault tolerance. Minor adjustments will easily cause defocused pictures, blurred edges and overall unclear imaging. It is extremely unfriendly to the elderly, children and digital beginners, greatly affecting the daily use experience. Adopting an upgraded dual focusing module integrating AI visual algorithm and ToF laser technology, this low-price projector realizes imperceptible full automatic focusing. It completes accurate focusing in milliseconds immediately after power-on. If the device is moved or tilted during viewing, the system can capture picture changes in real time and automatically correct focal length parameters without any manual operation, always presenting sharp and clear images. It supports desktop placement, side wall projection, ceiling suspension and temporary outdoor placement, enabling clear imaging at startup and no defocus after movement, completely eliminating tedious manual adjustment.

　　Extended from the core auto-focus function, the projector is equipped with an integrated full set of intelligent picture calibration functions, solving the common problems of skewed, deformed and poorly adapted pictures of traditional low-cost projectors in one stop. Traditional low-end projectors only support basic four-direction trapezoidal correction, which is prone to trapezoidal distortion, missing corners and picture offset when facing large tilting angles, irregular walls and surrounding obstacles. This product upgrades three core functions: six-direction full automatic trapezoidal correction, intelligent obstacle recognition and automatic screen fitting, breaking the limitations of traditional correction technology. Even with a large tilting angle, the device can intelligently crop the picture, automatically regularize the picture proportion and restore square and high-definition visual effects. Adapted to complex home environments, it can accurately identify obstacles such as wall switches, sockets, decorative paintings and furniture, automatically avoid blocked areas and adaptively adjust the picture size. Meanwhile, the built-in wall color adaptation function does not require professional pure white screens. It can automatically adjust color and brightness parameters for ordinary white walls, light-colored wallpaper and light background walls to accurately restore the true color of pictures, greatly reducing scenario restrictions and adapting to rental houses, dormitories and ordinary home environments.

　　Based on affordable pricing, the product fully upgrades hardware imaging functions to achieve high quality at a low price, completely eliminating the common problem of false parameter labeling and poor image quality of similar products. Abandoning low-end inferior light-transmitting lenses, the projector is equipped with high-transparency high-definition optical lenses and upgraded high-brightness LED light sources, strictly complying with the industry CVIA brightness actual measurement standards. It greatly improves light utilization and effectively reduces picture noise, chromatic aberration and dark area distortion. Supporting true physical high-definition resolution and 4K ultra-high-definition video decoding, it can smoothly play all mainstream audio and video files. It presents delicate, smooth and layered high-definition pictures for home drama watching, movie viewing, online courses, games, business document projection and PPT display. In addition, for long-time viewing scenarios, the built-in authoritative low blue light eye protection function can intelligently filter harmful short-wave blue light, relieve eye dryness, soreness and fatigue. It is suitable for high-frequency scenarios such as children’s long-term learning and viewing, home leisure entertainment and students’ online courses, protecting the eye health of users of all ages while ensuring excellent viewing quality.

　　The fully upgraded intelligent interaction functions enable this low-price projector to deliver a superior user experience far beyond products at the same price level. Equipped with a deeply optimized intelligent operating system, high-performance processing chip and sufficient running memory, the device runs smoothly and stably without stuttering or crashing, supporting free downloading, installation and uninstallation of massive audio-visual and office software. It integrates three core interactive functions: high-speed wireless WiFi networking, Bluetooth fast connection and one-click intelligent screen casting, fully compatible with Android, HarmonyOS, iOS and other full-system mobile phones, tablets and computers. It supports wireless mirroring, offline playback and multi-device linkage screen projection with stable transmission, ultra-low delay and no disconnection, perfectly meeting daily casting needs. Meanwhile, it adapts to global usage scenarios, built-in with multi-language operation interfaces, supporting customized boot logos, exclusive wallpapers and intelligent voice control. The operation logic is simple and easy to understand, accessible for the elderly and children. Adopting an ad-free boot design, it directly enters the main interface after power-on without long waiting, further improving the convenience and comfort of daily use.

　　The comprehensive optimization of battery power supply, stereo sound effect and silent heat dissipation functions makes up for the experience shortcomings of low-cost projectors and greatly improves the practicability and stability of the equipment. The portable body is built with a low-power high-capacity lithium battery and intelligent power-saving algorithm, which can automatically adjust power consumption according to screen brightness and operating status. It supports continuous video viewing and office projection for more than 5 hours after full charging, easily adapting to powerless scenarios such as dormitory power failure, outdoor camping and mobile office. The built-in professionally tuned stereo surround speaker optimizes multi-band sound effects for human voice, movies and music, delivering clear, three-dimensional and high-quality sound. It creates an immersive audio-visual experience without external speakers. Adopting a silent intelligent heat dissipation structure and efficient heat conduction design, the heat dissipation system can monitor body temperature in real time and intelligently adjust heat dissipation speed to quickly export operating heat. It effectively avoids brightness reduction, stuttering and crashing caused by overheating, with ultra-low operating noise that will not disturb viewing, resting and office work.
