The Crucial Role of Temperature Testing in Ensuring the Robustness of Car Monitors

Car monitors, equipped with LED displays and intricate chips on the PCB, undergo rigorous temperature testing to ensure resilience in diverse environments. The significance of low and high-temperature tests in the context of car monitors is paramount, considering the challenging conditions these devices face.

The working conditions of LED displays in cars can be exceptionally demanding. Summer exposes them to scorching heat, while winter tests their endurance against freezing temperatures, reaching as low as -40 ℃ in some regions.

Low-Temperature Testing:

For car monitors, especially those used in colder climates, the low-temperature test is crucial. In regions where temperatures remain below freezing throughout the year, starting the display screen in extremely low temperatures can be challenging. The materials of the LED display undergo varying thermal expansion and contraction coefficients, leading to potential issues like module gaps, extrusions, bulges, or even bursts.

In such conditions, electronic components may struggle to function normally, affecting the overall performance of the screen. Jeavox, understanding these challenges, has conducted extensive low-temperature tests in a simulated environment ranging from -35 ℃ to 85 ℃. This ensures that our outdoor LED display screens can withstand the harshest conditions, providing a solution that factors in the physical changes and potential challenges posed by extreme cold.

High-Temperature Testing:

High temperatures can be equally detrimental to LED displays. Exceeding the chip's carrying temperature can rapidly decrease luminous efficiency, leading to light decay and potential damage. The transparent epoxy resin used in encapsulation may undergo a phase transition, impacting the display's structural integrity.

Moreover, high temperatures accelerate defects in LED display chip materials, causing nonradiative composite centers and reducing light-emitting efficiency. The yellowing of transparent epoxy resin further affects light transmission, and the decay of phosphor contributes to light failure.

Jeavox, as a trusted manufacturer of in-vehicle monitoring systems, ensures the Backup Monitor LED displays and chips endure extreme temperatures. Our testing protocols involve subjecting the monitor camera to high-temperature conditions, resulting in the melting of the camera's shell. Remarkably, the LED display and camera chip continue to function despite the extreme heat.
