Problems solved by technology
[0003] The standard LED display screen has an operating temperature range of about -40°C to +60°C, and cannot be used in extremely low or extremely high temperature environments
In these extreme temperature environments, especially in high temperature environments, the LED display will produce obvious light attenuation, the performance will drop sharply and be damaged, which will affect the service life of the LED display
Faced with the above problems, the traditional solution is to place the electronic equipment with LED display in a large incubator, and adapt to the harsh working environment through the temperature adjustment system in the incubator. However, the traditional incubator has Problems such as high power consumption, large size, many faults, and high cost, if applied to wearable or handheld electronic devices, will be difficult to embed into the system

The present invention provides an LED display system suitable for a super-wide temperature range, which comprises an LED display screen, a TEC constant temperature plate and an intelligent temperature control circuit. the TEC constant temperature plate is arranged under the LED display screen and is in heat contact with the LED display screen, the TEC constant temperature plate is connected with the intelligent temperature control circuit and achieves programmable temperature control through the intelligent temperature control circuit. The system uses the semiconductor chiller TEC in the field of LED display screens, the intelligent temperature control circuit achieves intelligent temperature control of the TEC constant temperature plate, and the working temperature range of the traditional LED display screen can be greatly expanded. The system is suitable for extremely hot or cold work environments. Meanwhile, the TEC constant temperature plate in the system is super small in size, low in power consumption and cost, and particularly suitable for wearable or hand-held electronic equipment.
Description
technical field [0001] The invention relates to the technical field of LED display screens, in particular to an LED display screen system applicable to an ultra-wide temperature range. Background technique [0002] Light-emitting diode (LED) is a semiconductor component with the characteristics of energy saving, environmental protection, long life and small size. It is widely used in the field of display besides lighting. The LED display is a flat panel display, which is composed of small LED module panels, and is generally used to display text, images, videos, videos and other information. Due to the high brightness and clarity of LED displays outdoors, micro LED displays are often used as human-computer interaction interfaces in wearable and handheld devices that have developed rapidly in recent years. [0003] The standard LED display has an operating temperature range between -40°C and +60°C, and cannot be used in extremely low or extremely high temperature environments...
