Off-the-shelf modules are ideal for small handheld electronic devices

andersDX has added small TFT displays with an easy to integrate SPI interface and a power consumption of just 3mA. The new displays are ideal for a host of applications from handheld devices such as remote controls or test equipment for industrial, medical and consumer electronics. The company is initially offering 1.44” and 1.77” colour TFT modules featuring the SPI interface. The simple SPI can simplify a design, as the receiving hardware can be a simple shift register rather than a full UART. SPI is easily used to send data between microcontrollers and small peripherals such as shift registers, sensors or SD cards. It utilises separate clock and data lines, along with a select line for choice of device to communicate with. A key feature of the 1.77” displays is their very low profile, streamlined package of just 2.4mm deep, making it ideal for compact portable electronics. The 1.77" diagonal module is a full colour TFT display with a high contrast ratio of 700, a high brightness of 280cd/m2 and a low power consumption of just 3mA. There is also a 1.44” diagonal square display featuring the SPI interface. This module offers a contrast ratio of 350 and a brightness of 120cd/m2. Its package is 2.7mm thick. Both modules are suitable for use at temperatures between 20C to +70C. David Roberts, sales engineer at andersDX, commented, “These are attractive modules which will be popular in many portable electronics applications. As usual, andersDX is able to offer a high level of customisation to fit the needs of the application. This can include changing the flex, enhancing the backlight or adding touch. To widen the viewing angle, optical bonding and o-film can be added.”
