像素电路及其驱动方法和显示面板
By setting a first current control module and a second current control module in the Micro LED display panel, the light emission time can be adjusted independently, thus solving the problem of insufficient brightness in the Micro LED display panel and achieving higher display brightness and better display effect.

AI Technical Summary
Existing Micro LED display panels have low brightness within a single refresh cycle, which cannot effectively improve display brightness and results in poor display quality.
The design employs a light-emitting control module, a first current control module, and a light-emitting module. By setting the first current control module and the second current control module to control the potential of the first node according to the control signal input to their own control terminals, the light-emitting time can be controlled, thus achieving independent adjustment of the light-emitting time.
It significantly increases the light-emitting time within a single screen refresh cycle, improves display brightness and display effect, while reducing transient current, protecting the safety and reliability of the light-emitting module, and extending its service life.
