Car charging piles are generally outdoors, the light is strong, and they have to withstand severe weather such as wind, sun and rain, so their requirements for display screens are different from thermostats, notebooks, mobile phones, etc. What is the difference between outdoor display and general indoor display? At least the following differences:

1. brightness

As a passive display original, LCD screen needs backlight to get excellent display. However, there is a strong correlation between the brightness of the backlight and the brightness of the ambient light. If the brightness of the ambient light is high, the backlight also needs to have a high brightness, otherwise "light washing" will occur, which will affect the viewing effect of the display content. Therefore, the charging pile has strong outdoor light, and the charging pile display screen generally needs to reach more than 800nits, and higher brightness is required under special circumstances such as direct sunlight at noon. Compared with the indoor display of about 300nits, the brightness is already very high. But the brightness is too high, the human eye is not friendly, but also causes the system power consumption is too large and other negative problems.

2. power consumption

The main source of the power consumption of the LCD screen is the backlight. The higher the backlight brightness, the greater the power consumption of the LCD screen. Outdoor LCD screen must ensure high brightness, often bring high power consumption. Generally, the power consumption of outdoor screens of the same size is about 3 times that of indoor screens. In addition, the use of special backlight diaphragm technology can be improved to a certain extent to achieve high brightness and low power consumption, thereby saving energy. And can greatly improve the cost of the whole product in the cooling system.

3. heat dissipation mode

Due to the large power consumption of the outdoor display backlight, if the heat cannot be released, it will affect the display effect and even affect the normal operation of various components. However, the heat generated by the indoor display screen is small, and the heat dissipation requirement is not high. The heat dissipation method of outdoor display screen can increase the heat sink and fan lamp, and the indoor screen can be ventilated naturally.

4. IP protection level

IP protection level is a measure of electrical dust, to prevent foreign intrusion and moisture, waterproof intrusion capacity level indicators. Composed of two digits, the first digit indicates the level of dustproof and foreign object intrusion, and the second digit indicates the degree of moisture-proof and waterproof sealing. The larger the number, the higher the protection level.

Outdoor display screens experience wind and rain under natural conditions, so the protection level must reach IP65 outdoors, while indoor screens do not need such a high protection level.

5. LCD polarizer

Outdoor application products have to experience harsh sunlight radiation, which can easily cause the aging failure of the polarizer, so it is necessary to use a high-durability polarizer. In addition, the LCD display for drivers with polarized sunglasses should also be friendly, so it is necessary to set the angle of the front polarizer reasonably.

6. intelligent control

The outdoor environment changes greatly, especially the ambient brightness, temperature, humidity and other drastic changes, intelligent outdoor display can automatically adjust its relevant parameters according to environmental changes. The indoor environment is relatively stable, and the demand has this function.

7. riot

In unsupervised occasions, the outdoor display screen is vulnerable to malicious violence, and the display screen is artificially smashed. Therefore, it is necessary to use imported optical protective tempered glass for effective riot prevention. Indoor display does not have this requirement.
