At present, we have found that there may be a problem of blurred screen during fast sleep. The direct cause of the blurred screen is that the IC does not receive 0x28/0x10. Because of the particularity of the IC, before the panel enters sleep hid must stop scanning, i2c_hid_core_suspend before ili9882t_disable. This doesn't look very spec-compliant. So in order to solve this problem, the IC can handle it through the exception mechanism when it cannot receive 0X28/0X10. Handling exceptions requires a reset 50ms delay.
