Method and device for acquiring optical parameters of 3D display module

Abstract

The invention provides a method and a device for acquiring optical parameters of a 3D display module, and relates to the field of optical display. The optical parameter acquisition method of the 3D display module provided by the present invention stores the corresponding module code and optical parameter in the network server in advance, and when it needs to be retrieved, the first choice is to obtain the module code, and then, according to the model The group code requests optical parameters from the network server, and after receiving the module code, the network server inquires about the optical parameters corresponding to the module code, and returns the parameters to the local, so that the local receives the optical parameters. The method provided by this solution can enable users to obtain optical parameters more conveniently and quickly, and does not need to repeatedly calibrate the optical parameters of the 3D display module, which improves the convenience of use.

Description

technical field [0001] The present invention relates to the field of optical display, in particular to a method and device for acquiring optical parameters of a 3D display module. Background technique [0002] With the development of glasses-free 3D, the demand for glasses-free 3D display modules is gradually increasing. Due to the error in the bonding process between the lenticular lens and the display screen, the optical parameters of each naked-eye 3D display module will be more or less different from the standard value. The optical parameters of the 3D display module in different devices The parameters are not exactly the same either. Because of this, the 3D player first needs to know the optical parameters of the 3D display module before displaying, and then arranges the data according to the 3D display module, and finally plays it, so as to Guaranteed playback quality (if the optical parameters do not match the display module, the 3D display effect will be poor).

Problems solved by technology

[0003] For mass-produced naked-eye 3D display modules, usually, during production, it is necessary to record the optical parameters of each 3D display module, the amount of data is relatively large, and it is easy to confuse

Moreover, the optical parameters are generally pasted on the back of the module in the form of label paper. When the label paper is lost, the optical parameters are also easily lost.

[0004] For the 3D display module after leaving the factory, the loss of optical parameters will cause a lot of inconvenience. If there is a factory record (which records the optical parameters) in the calibration process before leaving the factory, then the optical parameters can be determined by asking the factory record, and then Re-set the optical parameters in the player; if the optical parameters are set incorrectly or the data of some specific parameters are changed due to operation errors, the 3D display effect will be poor or the display screen will be abnormal; if there is no factory record, you need to modify the 3D The optical parameters of the display module are recalibrated, and optical parameter calibration is a complicated and time-consuming process that can only be measured by professionals, causing inconvenience for users
