When EMC is a relevant requirement for integrating a display into an electronic system, the design of the PCBA integrated into the module is also an aspect to consider from the early stages of the project.
FIRST Components expands its offering with a family of TFT displays featuring a PCBA that has undergone third-party EMI testing and passed Class B requirements, available in three different sizes: 7", 10.1" and 21.5". This common characteristic makes it possible to address applications with different size requirements while maintaining the same approach to EMI management at board level.
For OEMs and designers developing medical equipment, this feature can be particularly relevant when evaluating display integration within the system, where electromagnetic compatibility is an important aspect of the project.
7" — WF70-1024600A8H#EP3-FC
The P/N WF70-1024600A8H#EP3-FC is a 7" 1024 × 600 TFT display featuring IPS technology, a typical brightness of 450 cd/m² and a viewing angle of 85/85/85/85. It integrates a control board with LT6911C, HDMI/DVI input and a PCAP touch interface managed by an ILI2130 controller with USB interface. The integrated PCBA has undergone third-party EMI testing and passed Class B requirements.
The combination of a compact form factor, HDMI and capacitive touch makes it suitable for embedded HMI systems where space and ease of integration are relevant factors.
10.1" — WF101-1280800LH#VSP3D-FC
The WF101-1280800LH#VSP3D-FC brings the same approach to a 10.1" format, with a 1280 × 800 resolution, IPS technology and high brightness of 900 cd/m².
The module features an HDMI interface, capacitive touch with a GT928 controller and USB interface, as well as dedicated connectors for integration with Raspberry Pi platforms. The EMI specification is listed as Class B, with a reported limit of 40 dBµV/47 dBµV.
The 10.1" format therefore provides an intermediate configuration for HMI interfaces requiring a larger display area than the 7", while maintaining an architecture based on HDMI and integrated touch.
21.5" — WFN2150HA2#0PN0-FC
For applications requiring a large-format display, the P/N WFN2150HA2#0PN0-FC offers a 21.5" Full HD 1920 × 1080 display, an IPS panel with a 89/89/89/89 viewing angle and a typical brightness of 500 cd/m².
The module integrates a control board with LT6911C, HDMI/DVI input and a 3H anti-glare surface. Here too, the PCBA has undergone third-party EMI testing and passed Class B requirements. The product is also indicated for medical devices, as well as industrial control equipment, information displays and kiosks.
A version with CTP, USB/I2C interface and OCR Bonding is also available for configurations requiring touch and optical bonding integration.
Three sizes, one common requirement
From the compact 7" interface to the large-format 21.5" Full HD display, this family makes it possible to evaluate different TFT sizes while maintaining a common element: a PCBA with verified Class B EMI performance. For a new medical project, the display size can therefore be evaluated together with the interface, touch, brightness, dimensions and system integration requirements.
