State display screen sending light wave in do not include the predeterminated frequency light wave；The described method includes:
The light wave of predeterminated frequency described in specified field emission to the surface of the display screen makes to be located at institute in the multiple code-point
The target code-point for stating specified region reflects the light wave of the predeterminated frequency；
The light wave of the predeterminated frequency of the object code point reflection is received, and light wave generates target dot chart based on the received；
The position on surface of the specified region in the display screen is determined according to the target dot chart.
9. according to the method described in claim 8, it is characterized in that, the multiple code-point is divided into more than one yard of area；Root
The position on surface of the specified region in the display screen is determined according to the target dot chart, comprising:
It identifies the target dot chart, determines the object code area where the center in the specified region；
The absolute position on surface of the object code area in the display screen and the center in the specified region are obtained described
Relative position in object code area；
Determine the center in the specified region on the surface of the display screen according to the absolute position and the relative position
Absolute position.
10. a kind of screen localization method, which is characterized in that be applied to display equipment, the display equipment includes display screen and sets
It is placed in the lattice layer on the surface of the display screen, the lattice layer includes multiple code-points, and the code-point can absorb predeterminated frequency
Light wave, other regions in the lattice layer in addition to the multiple code-point can reflect the light wave of the predeterminated frequency, wherein
It does not include the light wave of the predeterminated frequency in the light wave that the display screen issues；The described method includes:
The light wave of predeterminated frequency described in specified field emission to the surface of the display screen makes to be located at institute in other described regions
The light wave of the predeterminated frequency is reflected in the target area for stating specified region；
The light wave of the predeterminated frequency of the target area reflection is received, and light wave generates target dot chart based on the received；
The position on surface of the specified region in the display screen is determined according to the target dot chart.
