Touch screen HQ CH0039 — 4.3-inch 4‑pin resistive touchscreen, active area 105×64 mm

HQ CH0039 is a 4.3‑inch resistive touchscreen with a 4‑wire (4‑pin) interface and an active area of 105×64 mm. It is intended as a replacement panel or input surface for devices that use a standard 4‑pin resistive touch connection, providing a compact touch control solution for car GPS/navigation units, portable media players and other equipment that match these dimensions.

Advantages

The HQ CH0039 offers a defined active area of 105×64 mm and a standard 4‑pin resistive interface for straightforward replacement or integration. Its compact 4.3‑inch size fits many small displays and projects. The resistive touch technology works with a stylus, gloved finger or bare finger and requires a simple 4‑wire connection, which simplifies compatibility with common controllers.

Suitable for

• Car GPS and navigation head units
• Portable MP4/MP5 players and small multimedia devices
• Industrial displays and control panels with 4‑wire resistive input
• Handheld devices and DIY electronics projects
