Supports AI Voice Interaction

TheReflective Liquid Crystal Display (RLCD)is a specialized type of LCD that efficiently utilizes ambient light (such as natural sunlight or indoor illumination) instead of a backlight, achieving both energy efficiency and environmental friendliness. Thanks to its reflective design, RLCDs perform exceptionally well in bright environments, where conventional LCDs may suffer from glare and reduced visibility. By effectively reflecting external light, the RLCD can provide a clear, high-quality visual experience.

Application Scenarios
• * the 18650 Lithium Batt is optional.
