Problems solved by technology
[0004] For the cylindrical lens array grating, in the quality control of industrial production, the angle of inclination of the cylindrical lens array is a very important optical parameter. Specific patterns can be used to detect and calibrate the inclination angle of the cylindrical lens array (referred to as "inclination angle"). If the inclination angle does not meet the requirements, it can be adjusted through some post-remedial methods, but if the inclination angle problem is too serious, only Can be discarded as a defective product, or spend a lot of energy and manpower on rework and repair

The invention provides an inclination detection method and detection system for a cylindrical lens array, and relates to the fields of displaying and imaging. The inclination detection method for the cylindrical lens array comprises the steps of acquiring a basic image with a halo first, wherein the halo is present on the surface of the cylindrical lens array by irradiating the cylindrical lens array with a light source; and then calculating the direction angle of the halo according to the physical characteristic that the direction of the halo is perpendicular to the length direction of a grating prism in the cylindrical lens array, and determining the inclination of the cylindrical lens array, thereby improving the convenience of determining the inclination.
Description
technical field [0001] The invention relates to the fields of display and imaging, in particular to a detection method and a detection system for an inclination angle of a cylindrical lens array used in a display device. Background technique [0002] With the development of electronic technology, 2D display devices have been difficult to meet people's needs, and 3D display devices have emerged as the times require. Compared with 2D display, 3D display has a better sense of space and gives people an immersive feeling. 3D display is divided into two categories: glasses type and naked eye type. Glasses-free 3D is mainly used in public business occasions and portable devices such as mobile phones. In the field of household consumption, monitors, projectors or TVs all need to be used with 3D glasses, such as 3D theaters. In the glasses-based 3D technology, three main types can be subdivided: chromatic aberration, polarized light and active shutter, which are commonly referred ...
