3 Ιουν 2024 · Resolution: 240×320 pixels. Screen Size: Typically around 2.2 to 3.2 inches diagonally. Color Depth: 16-bit (65K colors) to 18-bit (262K colors). Interface: SPI (Serial Peripheral Interface. Backlight: LED backlight. Touchscreen Capability: Most ILI9341 displays come with a resistive touchscreen with an integrated touch screen controller (XPT2046).
11 Οκτ 2020 · So the simple answer is: you don't need a series resistor on the LED pin. But if you do, it needs to supply sufficient current for Q1 to saturate reliably. If the backlight is too bright, use PWM.

The 1K2 resistors are required to protect the display being damaged by the 5V logic levels from the UNO, these limit the current flow. Ideally we could use a level shifter but the resistors work fine. Update 2/2/2015. You can also now use the 2.2" QVGA TFT SPI display based on the ILI9341 driver.
11 Φεβ 2021 · Yes, you are correct, however it might give you more even backlighting if you used 4 resistors that equal ~19 ohms in parallel. Eg. 50, 100, 100, 100 for K1..K4. I would also check to see if the display is adequately bright at 50 or even 33mA.
