1. A digital message display device adapted for versatile mounting and display of digital text messages on a variety of planar surfaces, comprising:
a rectangular LCD digital display measuring either 8 inches by 12 inches for motor vehicle application or 18 inches by 36 inches for business window application, enclosed within a frame featuring at least six symmetrical suction cups for mounting;
a twisted nematic style LCD, with the option for IPS, OLED, or AFFS digital displays, to cater to diverse visibility requirements;

a power cord compatible with multiple power sources including a 12.0-VDC connection hardwired to a motor vehicle's fuse box, a temporary 12.0-VDC connection via a cigarette lighter, a 120-V AC outlet via a 12.0-VDC wall adapter, or a photovoltaic power panel, ensuring versatility in power supply; and,
a miniature keyboard connected to the display by a cable terminating in a detachable connection jack for message programming, featuring a microphone for voice-controlled input where manual operation is challenging, enhancing ease of message update and securing against unauthorized modifications; and,
wherein the device is specifically designed for attachment to the inner surface of a window using the braces, frame, and suction cups, with the frame and braces adjustable to ensure the display remains vertical, optimizing visibility to motorists and passersby; and,
wherein the device's installation and operation are facilitated by a configuration that allows for quick message changes, supports traffic management, enhances safety, and promotes effective communication in various contexts including motor vehicle emergencies and business advertising.
