LMT128005C15 1.28-inch round TFT display
240 × 240 px · SPI 4W · 15-pin FPC · GC9A01 · display-only module
LMT128005C15 is a 1.28-inch round TFT module with a 240 × 240 active area, SPI 4W interface and GC9A01 driver on a 15-pin FPC. This variant is display-only: the 15 pins carry GND, A0, SCK, SDA, CS, RST, LEDK, LEDA, VDD, VDDIO and TE. For the touch version on the same 15-pin pinout, see LMT128006C15.

Values above are transcribed from the 18-page supplier datasheet V1.0 (2023-08-25): general information p4, maximum ratings p5, electrical characteristics p6, outline drawing p10 and pin table p11. TBD means the supplier has not published the value; nothing is estimated.
Integration notes for LMT128005C15
The bus is 4-wire SPI: A0 selects data or command, CS is chip select, SCK is the serial clock, SDA carries data and RST resets the driver. LEDA / LEDK are the backlight anode and cathode; TE is the tearing-effect output used to synchronise frame updates.
The p10 drawing gives a ø35.6 mm panel and a 37.74 mm overall envelope along the FPC direction; the 33 mm VA circle surrounds the 32.40 mm LCD AA. The p4 table gives the same 32.4 × 32.4 mm active area, and 0.135 mm × 240 px = 32.4 mm.
The p4 table states two white LEDs in parallel, while p6 describes an edge-lit string of four white LEDs. The LED count is flagged for supplier confirmation; the electrical values are 2.8 V typ at 40 mA and 500 cd/m² typ. IDD and weight are TBD in the supplier document.
Figure 6 is the supplier mechanical drawing, not a redraw; use it for the FPC position, bend area and tolerances. Orientation in the drawing differs from the product photo by 90°, which is normal for this series.
Model-specific questions
What resolution and interface does LMT128005C15 use?
240 × 240 pixels over SPI 4W, GC9A01 driver, on a 15-pin FPC.
Does this module include touch?
No. LMT128005C15 is the display-only variant; the touch version with the same 15-pin pinout is LMT128006C15.
Is the display round?
Yes. The active area is a ø32.4 mm circle inside a ø35.6 mm panel; the 37.74 mm dimension includes the FPC exit.
What is needed for a quotation?
Specify LMT128005C15, quantity, host voltage, FPC length if customized, and the operating environment. Price, stock and lead time are confirmed in the quotation.
