The difference between industrial displays and ordinary LCD monitors ②

Three. Use of machine materials

Due to the requirements of the environment, the material of the LCD TV housing is made of metal. And the internal boards and wires are industrial design, not easy to aging; energy saving and environmental protection concept embodied: low energy consumption design; environmental protection materials used. Regular appearance, easy to splice, combined installation and other industrial needs.

On the contrary, the whole shell of LCD TV is designed with non-metallic materials. The interior line is designed for civil use, and it is easy to start aging for a long time. In addition, the appearance of civil television is mostly irregular appearance, with audio system, appearance arc system as an auditory and visual ancillary facilities, the construction of the overall beauty and effect will be greatly reduced.

Four. Control interface

The LCD can be controlled by S232 serial port, with more than 200 open control passwords, which is suitable for various industrial environments. Convenient use of multi-display, without the need for remote control can control all display devices, and can be assisted, timing boot, delay boot, machine self-test and other industrial requirements.

On the contrary, LCD TV can also be controlled by S232 serial port. But it can only realize the control commands that the remote control has. Industrial control can not be achieved.

Five, no fan architecture

LCD displays are designed without mechanical exhaust fans to maintain air flow and heat dissipation, thereby avoiding dust and fan noise problems caused by mechanical exhaust fans. When the internal temperature rises due to unknown reasons, the display automatic backlight system keeps the temperature below the maximum operating temperature.

On the contrary, due to the application environment, LCD TV has no strict requirements.

Six, color reduction degree

If the definition is mainly determined by the amplitude-frequency characteristics of the video channel, the reduction is mainly determined by the chroma signal of red (R), green (G), blue (B) in the display and the phase of the brightness signal. Because the display is usually a static image, the display color reduction requirements are higher than the television, so professional display channels in brightness, chroma processing and R, G, B processing should have accurate compensation circuit and delay circuit to ensure that the bright / color signal and R, G, B signal phase synchronization.

On the other hand, the LCD TV is displayed after polishing through the use of environmental requirements. It can not fully reflect the actual effect.

Seven. Port

LCD usually uses industrial ports such as RGB BNC color difference band self-locking mechanism interface and professional DVI-D video interface.

On the contrary, LCD TV has no BNC self-locking color difference input interface and DVI-D interface.
