Description
1.1 inch TFT LCD 135×240 spi screen
This is actually an active matrix color TFT liquid crystal display with a 1.14-inch display area. Adopting a vertical screen design, this spi screen boasts a resolution of 135×240 pixels, delivering delicate and rich picture details. The core of this module lies in its integrated ST7789H2 driver chip and communication via SPI ; this design enables the spi screen to ensure high-speed refresh while greatly saving the I/O port resources of the main control chip.
With a compact structure, the lcd features an overall dimension of only 17.6×31.0x1.65mm and an effective display area of 14.86×24.91mm, making it extremely suitable for portable devices with limited space.
Meanwhile, we also provide users with the HTM-H011A1-SPI-V0 driver module combination of the same series, as well as the TFT-H011A1QCIFT5N15 model of the same size with an MIPI interface, which can be matched with the spi screen to meet more diverse application requirements of customers.
Core Highlights and Diverse Application Scenarios of the SPI Screen
- In smart wearable devices, the spi screen is suitable for smart bracelets, sports bracelets, portable heart rate monitors and other products. Its small size fits the design needs of wearable devices, and the low-voltage and low-power consumption characteristics save battery power. With a brightness of 350cd/㎡, the lcd ensures visibility both outdoors and indoors, and can display core information such as time, heart rate and step count.
- In the field of portable consumer electronics, the display is applicable to portable Bluetooth speakers, mini players, car mini display terminals and so on. Its unfolded FPC design simplifies the assembly process, and the SPI interface is compatible with mainstream main control solutions, allowing the spi screen to meet the basic display needs of playing information, power volume, vehicle data and more.
- In terms of industrial control and portable testing equipment, the wide temperature characteristic of the display enables it to work stably in complex environments such as industrial workshops and outdoor testing. The SPI-4L interface ensures stable communication, so the spi screen can display testing data and equipment status in real time and accurately, and its small size makes the testing equipment more portable.
- In IoT terminal devices, the display conforms to the miniaturization and low-power consumption needs of smart sensor nodes and smart home mini controllers. The SPI interface can quickly form a network with IoT main control modules, enabling the spi screen to realize the visualization of device status and collected data.
- In small medical auxiliary equipment, the clear display effect of the display ensures the accurate presentation of medical data of devices such as blood glucose meters and oximeters, and its wide temperature and stable performance make the spi screen run reliably in different environments.
In addition, the lcd can also be applied to niche fields such as children’s electronic toys and mini model airplane remote controls, featuring extremely strong adaptability.
Technical Q&A about the SPI Screen
Q2: What is the viewing angle of the product, and which application scenarios is it suitable for?
A: The viewing direction of the spi screen is Free O’Clock (U80/D80/L80/R80), with a viewing angle of 80° for up, down, left and right directions, belonging to a wide viewing angle design.
The content on the lcd can be clearly seen even when viewed from a non-frontal angle, which is suitable for scenarios that do not require fixed frontal viewing such as smart wearables, car mini terminals and portable testing equipment, improving the convenience of use.
Q: What advantages does the SPI-4L interface have over the ordinary SPI interface?
A: SPI-4L is a four-wire SPI interface. Compared with the two-wire SPI interface, the spi screen’s SPI-4L interface adds communication lines, which improves the data transmission rate, ensures the real-time transmission of display data and avoids picture delay and freeze.
At the same time, as an industry-standard interface, it is compatible with mainstream main control chips, and the spi screen has stronger communication stability and anti-interference ability, suitable for complex environments such as industry and outdoor, and greatly reduces the difficulty of development and integration.
