AI Technical Summary
In existing smart whiteboard triple-slot display devices, inconsistent brightness and color temperature between the main screen and the secondary screen lead to inconsistent display effects. In addition, abnormal power-on timing may damage the circuit board, and the synchronous adjustment of display parameters is complicated.
The brightness and color temperature of the main display module and the secondary display module are adjusted by the main control circuit, the secondary control circuit and the adjustment unit respectively to make them consistent. The backlight brightness parameters are recorded and adjusted by lookup table and test element to ensure display consistency and circuit safety.
It improves the consistency of display effects, avoids the risk of circuit damage, simplifies the process of synchronously adjusting display parameters, and enhances the interactive teaching effect.
