When frequency error factor is to quenching frequency 529MHz, it is finely adjusted according to the reference value of screen parameter, and synchro measure horizontal-scanning interval,
Determine that the value that horizontal-scanning interval is the screen parameter after fine tuning under 7.18us state is target value.This is mainly due to above-mentioned pre-
If frame per second calculation formula is only theoretical calculation formula, actually since the physical difference of device is anisotropic, the accuracy of this reference value is simultaneously
It is not very high, and the numerical value of MIPI transmission frequency and screen parameter is practical differs larger (MHz and tens, several hundred difference),
Display screen horizontal screen parameter is affected to exhibit stabilization simultaneously, so consider to correct level based on actually detected result
The value of screen parameter, so as to improve stability.
If the vertical screen parameter includes following at least one in addition, the screen parameter only includes vertical screen parameter
Kind: the VBP, the VFP and the VAS, then the target screen parameter value can be equal to described with reference to screen parameter value, i.e.,
The porch value for adjusting vertical direction does not influence row scanning duration.
As it can be seen that, in the case where screen parameter includes horizontal screen parameter, electronic equipment being capable of root in the embodiment of the present application
Actually detected result is combined to be modified reference screen parameter value according to row scanning duration constraint condition, to show after improving frequency hopping
Display screen stability.
