Abstract: A control device includes a memory and a processor. The memory is configured to store a time comparison table. The processor is configured to determine whether a displayed image is a still image. When the displayed image is determined to be a still image, the time comparison table is queried for a corresponding still image judgment duration according to an average pixel level and a type of the still image.

Abstract: The present invention discloses an analysis method of a tensioning process of a fine mask plate. The analysis method, based on the simulation function of ANSYS software, finds an appropriate tensile force for stretching a fine mask plate and a corresponding actual counterforce applied to a metal frame before each fine mask plate is welded onto the metal frame through establishing a finite element model of the fine mask plate and a finite element model of the metal frame.. The analysis process requires no physical tests, thereby effectively avoiding damaging the fine mask plate and further effectively saving the test cost.
