solution is to double the screen refresh frequency to 120 times per second to avoid flashing problems.LCD 3D Stereoscopic glasses must be active, so the structure is more complex than passive 3D stereo glasses, although the cost of the playback equipment is lower, but the cost of glasses is much higher. In the current mainstream infrared synchronization method, it must be equipped with additional receiving control circuit and battery. And the interlaced shielding of the LCD lens will affect the
In web development, there are frequent grouping requirements for the drop-down select box (select). For example, the Sega model selection shown in, take the sedan 1.6l as an example.
In the figure, "Sega 2011 sedan 1.6 automatic" and "Sega 2011 sedan 1.6 manual" are selected as select groups. The following describes how to implement them in JSF.
Method 1: Use se
