Problems solved by technology
However, the luminous intensity of the light-emitting diode is affected by temperature and operating current. When the operating current is fixed, the luminous intensity changes with the external environment such as temperature, so that the sensitivity of the infrared button changes accordingly, which may lead to oversensitivity of the infrared button. or insensitive
In addition to light-emitting diodes, other electroluminescent devices with similar characteristics to light-emitting diodes also have the problem that the luminous intensity is too large or too small due to changes in the external environment caused by a fixed operating current.

The present application provides an apparatus, method and electroluminescence system for adjusting the working current of an electroluminescence device. The method includes: converting an optical signal of the electroluminescence device into an electrical signal; when the electrical signal satisfies a preset When the working current adjustment conditions are met, an adjustment instruction for adjusting the working current of the electroluminescent device is generated; and the working current of the electroluminescent device is adjusted according to the adjustment instruction. In this application, the optical signal of the electroluminescent device is converted into an electrical signal, and when the electrical signal satisfies the preset working current adjustment conditions, the working current of the electroluminescent device is adjusted, so that the luminous intensity of the electroluminescent device is kept at the preset value within the appropriate range.
Description
technical field [0001] The present application relates to the field of electrical technology, and in particular to a method, device and system for adjusting the working current of an electroluminescent device. Background technique [0002] The infrared button on the display panel in the prior art includes a light emitting diode, which is a kind of electroluminescent device. The working current of the LED is fixed, and the luminous intensity of the LED affects the sensitivity of the infrared button. However, the luminous intensity of the light-emitting diode is affected by the temperature and the operating current. When the operating current is fixed, the luminous intensity changes with the external environment such as temperature, which causes the sensitivity of the infrared button to change accordingly, which may lead to oversensitivity of the infrared button. or insensitive. In addition to light-emitting diodes, other electroluminescent devices with similar characteristi...
