tft lcd offline panel price

Note: Says it works with LaserGRBL, but can not get it to connect to the web port (LaserGrbl finds it, but can not connect). All the software I find for it is in chines I think. So right now the only way to use it is offline and you need a SSD card to do that so you better order one of those too... As of now I would give it 1 stars.

This long-running case against multiple LCD makers alleged a wide-reaching conspiracy to fix prices on flat screen panels used in monitors, TVs, laptops and smart phones. IMS Consulting & Expert Services clients represented a class of direct purchaser plaintiffs, and the case proceeded to trial against the final remaining defendant, Toshiba Corp. This was one of the few antitrust class actions ever tried to a successful verdict.

After a six-week trial, jurors needed little time to return a verdict against Defendant Toshiba, finding that they had conspired with other LCD makers to fix prices of flat screen panels. This resulted in a $261 million award against Toshiba.

You are sourcing voltage from the switch, which would make sense since when you flip the switch, it would turn on the system and screen at the same time. Problem is, CORRECT ME IF I"M WRONG AS I DIDN"T MEASURE, the voltage at the switch would be 9v since it"s so close to the power jack. Appplying 9v directly to the power/av connector on the LCD driver board is wasting (dissipating through heat or other means) 4v, as the step-down voltage converter has a 5v output, which is typical for these small sized LCD drivers. In fact, your board/display combo probably can still function properly all the way down to 3.3v which the LCD panel is rated.
