SP14Q005 5.7" display modules for KOE

For a white screen or no display, please troubleshoot with the following steps: Power Check: Verify that the supply voltage and current meet the requirements and the polarity is correct. Backlight Check: Shine a light at an angle onto the screen to see if there is a faint image. If yes, the issue is with the backlight (e.g., damaged CCFL tube/LED, faulty backlight driver circuit). Signal & Connection: Check if the ribbon cable is connected properly and undamaged. Ensure the main control board is correctly outputting sync and data signals. Initialization Sequence: Make sure the microcontroller has sent the correct initialization command sequence as required by the datasheet.

The SP14Q005 is a relatively old model and is likely discontinued. It is recommended to contact KOE or its authorized distributors directly for the most accurate End-of-Life (EOL) information and stock availability. For replacements, you might consider 5.7-inch QVGA TFT modules from other manufacturers, but pay close attention to compatibility regarding the interface, physical dimensions, mounting holes, and driving method.

No, it is not compatible with the HD44780. The HD44780 is a controller for character LCDs, whereas the SP14Q005 is a graphic dot-matrix display. You need to use its dedicated driver IC (often custom-made for KOE) and send image data and control commands via a parallel bus or specific interface from a microcontroller or FPGA

This module typically uses a single-row or dual-row connector as its interface. The specific pinout (including power, ground, RGB data lines, sync signals, enable signals, etc.) must be confirmed by consulting the official datasheet. The pin arrangement may vary between different production batches, so it is highly recommended to refer to the accompanying technical documentation.

The SP14Q005 is a 5.7-inch LCD module, utilizing STN or TFT technology (depending on the specific version). It features a typical resolution of 320 x 240 pixels (QVGA), supports 65,536 colors, and is commonly equipped with CCFL or LED backlighting. It includes a dedicated driver IC and interface for KOE.
