1results about How to "Avoid decoding errors" patented technology

Embodiments of the present application provide a sampling point determination method, device, equipment, storage medium and program product. A calibration signal of a backlight driver is obtained. The calibration signal includes at least first bit data and second bit data. The duration of the first level period of the first bit data is greater than the duration of the first level period of the second bit data. The first level period of the second bit data is a pre-stage period. The duration of the data period of the first bit data is determined according to the difference between the duration of the first level period of the first bit data and the duration of the first level period of the second bit data. Then, the duration of the data period of the first bit data and the product of any value within the preset range of the sampling ratio are added to the pre-stage period to determine the sampling point of each bit data in the backlight driver. Thus, the sampling point can be ensured to fall in the data period in the case of signal distortion, the calculation accuracy of the sampling point is improved, and data decoding errors are avoided.
