You are referring to a 1.69-inch rectangular LCD panel with a resolution of 240x280 pixels. It uses IPS (In-Plane Switching) technology and supports MCU (microcontroller unit), RGB, and SPI (Serial Peripheral Interface) interfaces. This specification is ideal for use in small embedded systems and portable devices, such as smart watches, health monitors, and personal electronic accessories.
Display Features
This 1.69-inch TFT LCD module has a resolution of 240x2801
, which means it can provide enough details to display clear text and images on a smaller screen. The use of IPS technology ensures a wide viewing angle, and maintains good color accuracy and contrast even when viewed from the side15
. This allows the screen to provide a consistent and high-quality viewing experience at various angles, which is particularly useful for applications that require multi-angle viewing.
Interface Options
The LCD panel provides three main interface options:
MCU interface: Directly connects to the microcontroller, which simplifies the system integration process and helps reduce power consumption.
RGB interface: Image display is achieved by transmitting red, green, and blue signals in parallel, suitable for application scenarios that require fast refresh rates.
SPI interface: This is a serial communication protocol that is suitable for situations where the data rate is not particularly high. At the same time, it occupies a small number of pins and reduces the space required on the circuit board4
.
Viewing angle and display mode
The full viewing angle function is an important feature of this display, which allows users to clearly see the content on the screen from almost any angle. This is very important for devices that may be used in different environments, such as smart watches worn on the wrist or handheld health monitoring instruments5
. In addition, since it adopts an LED backlight design, it can provide a uniform and bright display effect, enhancing the user's reading comfort10
.
Application field
Due to its compact design and excellent display performance, this type of 1.69-inch TFT LCD panel is widely used in smart homes, smart wearable devices and other portable electronic products. For example, in smart watches, it can be used to display information such as time, weather forecast, sports data, etc.; in medical equipment, it can be used in miniaturized instruments such as heart rate monitors and blood glucose meters to provide users with an intuitive and easy-to-read operation interface
.
Technical parameters
According to the information provided by different suppliers, the specific technical parameters of this 1.69-inch TFT LCD panel also include but are not limited to the following points:
Active display area: approximately 30.07mm (W) x 35.56mm (H)6
Brightness: usually between 200 nit and 300 cd/m², depending on the model and manufacturer
Operating temperature range: generally supports an operating ambient temperature of -20°C to +70°C8
Supply voltage: mostly an operating voltage of around 3.3V9
Special instructions
It is worth noting that some versions of the 1.69-inch LCD panel are also equipped with a touch function, which increases the possibility of human-computer interaction. For example, some models have a built-in CST816D capacitive touch chip that can communicate via the SPI/I2C interface, allowing more complex user input2
In addition, in order to ensure the durability of the product, the display and lens, as glass products, should be properly stored and used to avoid damage caused by wear or cracking, which are usually not covered by the warranty2
.
In summary, this 1.69-inch 240x280 resolution IPS LCD panel has become one of the ideal choices for many high-end smart devices due to its excellent display effect, flexible interface selection and wide applicability. If you are looking for a small-size display solution that is both beautiful and practical, then this product is undoubtedly worth considering.
