A method for constructing a lane-level navigation map is provided. The method may include: determining a change position of a lane in a road-level electronic map; extracting lane information of the change position of the lane, the lane information including a lane connectivity relationship; and storing the lane information in the road-level electronic map to obtain the lane-level navigation map.

Method and apparatus for constructing lane-level navigation map, device and storage medium

A timing controller includes: a field programmable gate array configured to generate a reference clock signal, and obtain at least one group of clock signals according to the reference clock signal. Each group of clock signals includes at least two clock signals, and a waveform of each clock signal is same as a waveform of the reference clock signal, and active levels in different clock signals are provided with a delay of a preset duration. The reference clock signal includes a first clock sub-signal for first duration and a second clock sub-signal for a second duration. At least one output interface group is connected to the field programmable gate array. Each output interface group includes at least two output interfaces, and each of the at least two output interfaces is configured to output one clock signal of a group of clock signals corresponding to the output interface group.

Timing controller, display apparatus and display control method thereof

The invention provides a printed circuit board and a detection method for detecting a connection between the printed circuit board and a flexible circuit board, and a display panel. The printed circuit board, through a connector provided thereon, is connected to a flexible circuit board, the printed circuit board is provided thereon with at least one first detection structure for matching with at least one second detection structure provided on the flexible circuit board, and whether or not a connection between the printed circuit board and the flexible circuit board is correct is determined by detecting matching between the first detection structures and the second detection structures. Pins of the printed circuit board may be correctly connected to pins of the flexible circuit board, and a case that short circuit occurs and thus the signal lines are damaged and burned can be avoided.
