Description

Technical Field

[0001] The utility model relates to a liquid level device based on OLED display technology, belonging to the technical field of liquid level devices. Background Art

[0002] With the rapid development of information technology and display technology, organic light-emitting diodes (OLEDs) have been widely used in various display devices due to their excellent display effects and flexibility. OLED display technology, with its self-luminous characteristics, provides a wider viewing angle and higher contrast, especially in dark environments. In addition, the development of OLED has also driven its application exploration in non-traditional fields, such as wearable devices, medical devices, and industrial monitoring. In industrial applications, liquid level monitoring is one of the key technologies to ensure production safety, efficiency and quality. Traditional liquid level measurement technologies mainly include float type, pressure type, ultrasonic type and capacitive type, but these technologies have their own limitations. For example, the mechanical structure of the float level gauge is susceptible to corrosion or blockage, affecting its accuracy and reliability; and when the pressure level gauge handles viscous or solid-particle-containing liquids, its measurement results are easily affected by changes in the properties of the medium.

[0003] Existing liquid level measurement technologies often fail to meet the needs of high-end manufacturing and intelligent industries in terms of accuracy, stability, application scope, and user interaction interface. These technologies often rely on physical measurement principles, and in some extreme working environments, the stability and durability of physical sensors are challenged. For example, in high temperature or highly corrosive environments, the service life and performance of traditional sensors will be greatly reduced. Operators are required to frequently inspect or repair sensors. Sensors in existing technologies are often integrated structures, which are inconvenient to disassemble, making it inconvenient for operators to inspect or repair. Utility Model Content
