Advanced driver-assistance system (ADAS) information displays
Integrated navigation and vehicle information displays
Cockpit control centers for high-end vehicle models
A 12.3-inch display allows for a richer visual layout of content such as navigation, vehicle status, driver assistance information, media controls, and energy management.
For new energy vehicles, large-size displays also help automakers create smart cockpits with a more high-tech feel.
It should be noted that in this article, the 12.3-inch size is primarily analyzed as a typical custom size and market application direction for in-vehicle touchscreen displays; it does not represent the standard 12.3-inch stock products currently listed on Hangzhou Hongxiao Technology’s official website.
Hongxiao Technology possesses the capability to customize PCAP touchscreens and touch display modules. According to publicly available information on its official website, its PCAP product range spans 1.3 to 65 inches, and the company offers related customization services such as LCD/TFT, optical full lamination, and cover glass. Therefore, in-vehicle sizes like 12.3 inches can be designed according to specific project requirements.
The 15.6-inch size is a key representative of larger in-vehicle displays.
As automotive interior space and entertainment features continue to evolve, 15.6-inch displays can be used for:
passenger-side entertainment screens, rear-seat entertainment screens, commercial vehicle cabins, large center-console displays, and smart mobile terminals.
For front-seat passengers, a 15.6-inch display offers a more expansive visual experience for audio-visual entertainment, navigation assistance, information browsing, and in-vehicle applications.
In MPVs, commercial vehicles, and high-end new energy vehicles, 15.6-inch screens can also be used in rear-seat entertainment systems, providing passengers with a user experience closer to that of a tablet or mobile display device.

According to Hongxiao Technology’s publicly available product documentation, these 15.6-inch products can also support glove touch, water touch, and cover glass surface treatments such as AG, AR, and AF, depending on project requirements.
This means that 15.6-inch displays not only meet the demand for large-size displays but can also further optimize the touch experience and display performance for different in-vehicle environments.
From Single-Touch Functionality to Multi-Touch Interaction
The value of in-vehicle capacitive touchscreens goes far beyond simply “tapping.”
Modern PCAP capacitive touchscreens support multi-touch, enabling users to perform complex human-machine interactions through gestures such as tapping, swiping, and zooming.
For example:
Navigation Maps: Pinch to zoom the map.
Audio System: Swipe to browse songs.
Vehicle settings: Tap to adjust the air conditioning, lights, and driving modes.
Entertainment system: Use multi-touch gestures to control audio and video content.
This makes capacitive touchscreens an essential component of the digital experience in smart cockpits.
The Automotive Environment Places Higher Demands on Touchscreen Reliability
The interior environment of a vehicle differs significantly from that of ordinary consumer electronics.
In-vehicle touchscreens must withstand:
High and low temperatures, sunlight exposure, vibration, electromagnetic interference, dust, and frequent touch interactions.
