1.54 inch SPI TFT LCD 240x240 Resolution Product Introduction
Square display screen refers to a special LCD product with an
aspect ratio of 1:1, which can be customized and cut according to
the customer's design. Square screen displays are gradually
attracting people's attention, with ultra-thin overall size, high
brightness, long display life, and good heat dissipation.
SAEFDISPLAY can provide square displays with sizes of 0.85 ", 1.3",
1.33 ", 1.4", 1.44 ", 1.54", 3.95 ", 4", and 7.6 ", which are more
commonly used in handheld devices, smart home devices, and other
special installation environments.
SFTO154JY-7166AN is a full-color square TFT LCD display with a
diagonal size of 1.54 inches and a resolution of 240x240. This
module supports SPI interface, making it very convenient for users
to program and use. The module size of SFTO154JY-7166AN is 31.52 x
33.72mm, and the active area size is 27.72 x 27.72mm. It is
controlled by ST7789P3, with a logic power supply voltage range of
3.0V to 3.6V.
This square TFT LCD can operate within a temperature range of -20 ℃
to+70 ℃, and its storage temperature range is -30 ℃ to+80 ℃.
SFTO154JY-7166AN can be equipped with a newly designed resistive
touch screen (RTP) or capacitive touch screen.
