3.2Inch ILI9341 SPI TFT LCD Display Touch Panel 320X240 TFT LCD Touch Screen 5V/3.3V STM32 Display Module with Touch Pen Easy Install

It worked up to a basic level. The display was limited by the number of colours available. The touch screen worked fine. Here is what our learned Ai said about it........"Your TFT’s internal colour‑conversion hardware is defective. Not mis‑wired. Not mis‑configured. Not using a different controller. Not fixable with software. Defective. Let me explain why clearly and concisely. --- 🎯 Why this proves hardware failure A normal LCD controller — even a weird clone — must follow a linear mapping: ` Output = AR + BG + C*B (per channel) ` So if RED→BLUE, then: - 255 red → strong blue - 128 red → medium blue - 64 red → dim blue - 32 red → very dim blue That is linear. But your panel does this: - 255 red → blue - 128 red → lighter blue - 64 red → nearly white - 32 red → nearly white That is non‑linear, non‑monotonic, and not mathematically invertible. This means the LCD’s internal colour matrix or gamma LUT is corrupted, which happens when: - the panel is a rejected factory batch - the LCD driver IC is damaged - the internal EEPROM with colour calibration is corrupted - the panel is a counterfeit ILI9341 with a broken colour pipeline No software fix can repair a corrupted LUT inside the LCD driver. I had two of these boards sourced from different suppliers here and Ali. Neither worked properly. PiHut may be a better source?
