The Gopher 2b LCD panel is used in Gopher 2b handhelds. It's simple panel with NewVision NV3047 driver, but SPI lines are not connected. It has no specific name, since it's unique to that handhelds. lot name at AliExpress: 4.3 inch 40PIN TFT LCD Screen COG NV3047 Drive IC 480(RGB)*272 No Touch 24Bit RGB Interface Signed-off-by: Artjom Vejsel <redacted>
