Abstract
An optical detection apparatus and method for detecting a display panel is provided. The apparatus includes photosensitive units arranged in an array. A minimum distance between adjacent photosensitive units is less than a sub-pixel size of the display panel; the photosensitive units in adjacent rows have a position offset in a first direction; and an offset distance corresponding to the position offset is less than the sub-pixel size of the display panel.
Claims19
An optical detection apparatus for detecting a display panel, comprising photosensitive units arranged in an array, wherein a minimum distance between adjacent photosensitive units is less than a sub-pixel size of the display panel, and the photosensitive units in adjacent rows have a position offset in a first direction, an offset distance corresponding to the position offset being less than the sub-pixel size of the display panel;
- wherein a pitch between adjacent photosensitive units is N times the minimum distance between the adjacent photosensitive units, N being an integer greater than or equal to 2;
- and the pitch between adjacent photosensitive units is an integral multiple of the offset distance, wherein the pitch between the adjacent photosensitive units is a distance between center points of the adjacent photosensitive units.
A method for detecting a display panel by using an optical detection apparatus, the optical detection apparatus comprising photosensitive units arranged in an array, wherein a minimum distance between adjacent photosensitive units is less than a sub-pixel size of the display panel, and the photosensitive units in adjacent rows have a position offset in a first direction, an offset distance corresponding to the position offset being less than the sub-pixel size of the display panel;
- wherein a pitch between adjacent photosensitive units is N times the minimum distance between the adjacent photosensitive units, N being an integer greater than or equal to 2;
- and the pitch between adjacent photosensitive units is an integral multiple of the offset distance, wherein the pitch between the adjacent photosensitive units is a distance between center points of the adjacent photosensitive units;
- the method comprising:
- determining a movement route of the display panel based on a size relationship between the optical detection apparatus and the display panel;
- controlling the optical detection apparatus to acquire screen information of the display panel at a first position;
- controlling the display panel to move along the movement route, and controlling the optical detection apparatus to acquire screen information of the display panel again every time the display panel moves a first distance, until the respective acquired screen information collectively embodies a complete screen of the display panel;
- and
- performing optical detection on the display panel based on each of the acquired screen information.
A computer device, comprising a processor and a memory, wherein
- the memory is configured to store a software program;
- and
- the processor runs or executes the software program stored in the memory to cause the computer device to perform a method for detecting a display panel by using an optical detection apparatus;
- the optical detection apparatus comprising photosensitive units arranged in an array, wherein a minimum distance between adjacent photosensitive units is less than a sub-pixel size of the display panel, and the photosensitive units in adjacent rows have a position offset in a first direction, an offset distance corresponding to the position offset being less than the sub-pixel size of the display panel;
- wherein a pitch between adjacent photosensitive units is N times the minimum distance between the adjacent photosensitive units, N being an integer greater than or equal to 2;
- and the pitch between adjacent photosensitive units is an integral multiple of the offset distance, wherein the pitch between the adjacent photosensitive units is a distance between center points of the adjacent photosensitive units;
- wherein the method comprises:
- determining a movement route of the display panel based on a size relationship between the optical detection apparatus and the display panel;
- controlling the optical detection apparatus to acquire screen information of the display panel at a first position;
- controlling the display panel to move along the movement route, and controlling the optical detection apparatus to acquire screen information of the display panel again every time the display panel moves a first distance, until the respective acquired screen information collectively embodies a complete screen of the display panel;
- and
- performing optical detection on the display panel based on each of the acquired screen information.
