The Difference Between Industrial LCD and Consumer LCD
When customers apply their products to LCD screen selection, they will face the problem of choosing industrial LCD screen or ordinary LCD screen. You should know that the price of industrial display is much more expensive than ordinary consumer display, so why is consumer display more expensive than industrial LCD screen?
Today we will tell you how to distinguish industrial screen from ordinary consumer screen. What is the difference? I hope it will help you with your future product selection.
Generally speaking, due to the different working environment of industrial LCD screen, it is much worse than the general living environment. For example, there is dust in some workshops, and outdoor use may be exposed to wind, sun and rain, sudden falls, and extreme cold and high temperature outdoors. It is precisely because of these special environments that industrial LCD screens are sturdy and durable. Whether it is high or low temperature, whether it is sun and rain, industrial LCD screens can work normally.
Reliability
Industrial LCD screens need to work 24 hours a day, 365 days a year. The environment of power supply and industrial display is much worse than that of TV display used at home, so it requires more stability. At the same time, industrial displays have higher performance requirements than ordinary displays, such as component voltage, current, humidity, high and low temperature, etc., and the design direction is also different. For example, a TV will age after being turned on for 8 hours, while an industrial display will age after being turned on for 24 hours under high temperature and high humidity.
Industrial display screens are mainly used in industrial automation, medical, military and other industries. The difference between industrial display screens and ordinary display screens is that industrial display screens usually adopt special shockproof designs. Industrial-grade LCD screens can generally reach an operating temperature of -30~+80, which is more stable and reliable in harsh environments than consumer-grade LCD screens.
Shell
The shell design of industrial LCD displays generally adopts a full steel design. The panels are divided into different materials such as ordinary iron plates, stainless steel plates, and aluminum plates, and have special dustproof and shockproof designs.
The shell material of ordinary consumer displays is generally plastic shell, and plastic shells have poor radiation suppression, weak anti-interference ability, unstable signals, and interruptions.
Working temperature
Industrial LCD monitors generally work at a temperature between -20 and 70 degrees. Some special industries have higher environmental requirements and require LCD monitors with a wider temperature range (-40 to 85 degrees). Innolux, Mitsubishi, etc. have also produced ultra-wide temperature industrial LCD screens of suitable sizes.
Comparison
Sometimes users cannot guarantee the best viewing distance or ideal lighting conditions for industrial product LCD displays, and high-contrast LCD monitors are necessary. A contrast ratio of 450:1 is ideal for 10.4-inch, 12.1-inch, or 15-inch monitors used in most industrial applications.
Display brightness
Since ordinary consumer monitors are mostly used in indoor environments, the brightness is about 250~300cd/m2 (NIT), and LCDs with a diagonal size of 15 inches are most commonly used. However, monitors with this brightness level cannot meet the requirements in industrial environments because the ambient light is strong and its brightness can easily exceed the brightness of the LCD backlight.
In addition, touch screens are often used in industrial environments, which will reduce the brightness of the display and appear darker. In common medical, industrial and public telephone booth applications, the required brightness must be at least 450cd/m2. Response time In the past, the response time of passive display technologies including LCDs was very poor compared to active light-emitting display technologies.
Service life
For the consumer market in the industrial market, whether it is used in industrial equipment or medical equipment, the requirement for backlight life is often more than 5W hours. The maximum working life of consumer screens is 3W hours. When used for more than 3W hours, the screen backlight will gradually age, while the minimum backlight life of industrial screens is 5W hours. The longer backlight life can reach 7W and 10W hours, which can be used for five and a half years under 24-hour continuous operation.
Long-term supply
Compared with consumer screens, the supply cycle of industrial screens is more than three years, or even more than three years (some 8.4-inch, 10.4-inch, and 12.1-inch screens have a supply cycle of up to 10 years, and they are still in stable supply), but ordinary consumer screens are often out of stock or discontinued in half a year to a year. For example, mobile phone and tablet LCD screens are updated very quickly. If medical products are selected, the LCD screens will be discontinued before the relevant qualification certification begins, which will seriously affect the follow-up work of the entire project.
From the comparison of the above seven points, the difference between industrial display screens and ordinary display screens is not only the price, but also the selection of raw materials for industrial LCD screens is more stringent: in order to create such an “iron wall” industrial LCD screen, there must be certain requirements and specifications in the selection of materials, and in order to achieve high reliability, the internal structure also requires industrial design.
