Performance advantages of elevator LCD advertising machine

The performance advantages of its elevator LCD advertising machine are mainly as follows:

The first, 175 degree viewing angle gives you the perfect visual effect.

The viewing angle is one of the main items of the elevator floor display. Although we can view the images presented by CRT monitors from various angles, the elevator floor display (LED) must be viewed from the front to get the best visual effect. If viewed from other angles, the brightness of the picture will be dimmed (brightness reduction), color changes, and even some products will change from positive to negative.

Second, the professional industrial control host, the performance is more stable

Elevator multimedia professional industrial control host for elevator multimedia research adopts new technologies and new products such as “embedded system”, “fanless structure”, “chassis cooling”, “solid-state hard disk”, “box” and “flat”. The development trend of products “miniaturization”, “intelligence” and “low power consumption” has greatly improved the system stability of the industrial computer and reduced the manufacturing and application costs.

Third, large and wide viewing angle, you can enjoy clear pictures in any direction

The elevator floor display uses the latest technology to expand the viewing angle of the screen. In this way, the best-performing elevator floor display can be approximated to the CRT display by about 87.5 degrees on the left and right sides, that is, the horizontal viewing angle is 175 degrees, and the content of the screen can be seen from almost any angle. In general, a viewing angle of 140 to 160 degrees is a basic indicator for a large elevator floor to absorb its display. For smaller 15" or less than 15" elevator floor displays, a 120 degree viewing angle is sufficient to display a complete picture. The viewing angles on the left and right sides are generally larger than the viewing angles above and below, that is, the vertical viewing angle is smaller than the horizontal viewing angle (generally between 120 and 140 degrees).

Fourth, the signal acquisition board is designed to be more powerful for elevator multimedia design.

The elevator multimedia display displays the various operating states of the elevator in real time (up and down floor display, overload, fire, maintenance, driver and other signals, and can access the accessible signal source according to customer requirements) to replace the original LED display. The elevator signal wiring access supports parallel, serial, CAN protocol interfaces, etc. (can be customized according to user requirements). If the customer can not provide the protocol interface, you can use the elevator signal acquisition board developed by our company to display the signals on the upper and lower floors of the elevator, overload, fire, maintenance, driver, etc., and access the accessible signal source according to customer requirements. When the elevator is in the absence of a call signal for a few minutes (customized time can be customized according to user requirements), the elevator's uplink and downlink signals will automatically disappear, leaving only the floor signal. When someone calls the elevator, the elevator's uplink and downlink signals will automatically appear. It is consistent with the protocol signal of the elevator; of course, in particular, when the elevator has not reached the first floor on the second floor, the downward direction arrow is already the upward direction arrow. The wiring is simple, the signal is stable, and it is absolutely consistent with the protocol interface signal.
