Technical requirements rarely stop at the LCD itself. A custom display may require specific brightness, interface, touch, cover glass, optical bonding, FPC, operating temperature, and mechanical integration.

Electromagnetic interference (EMI) is one possible cause of touch instability, but similar symptoms can result from other electrical or configuration issues. Identifying the actual cause requires testing the touchscreen in the context of the complete industrial system.

FANNAL Electronics is exhibiting at the 26th China International Industry Fair (CIIF 2026), taking place from October 12 to 16 at the National Exhibition and Convention Center (NECC) in Shanghai, China.

Most LED-backlit LCD modules use two common configurations: direct-lit and edge-lit LED backlights. The appropriate choice depends on the display size, target luminance, available installation space, optical requirements, and cost constraints.

Bar type displays provide an alternative when conventional display formats do not match the mechanical or interface requirements of a product. Their elongated form factor can be useful for industrial equipment, transportation systems, automotive interfaces, kiosks, and other specialized applications.

The key to selecting a bar-type display is to evaluate the complete system rather than focusing only on aspect ratio or diagonal size. Mechanical dimensions, active area, resolution, interface, touch, optical structure, and environmental requirements should be defined together.

Marine displays must maintain clear visibility and reliable touch operation under sunlight, humidity, salt spray, vibration, and changing temperatures. This guide explains the key display, touch, and environmental requirements for marine control systems.

Reflective, transmissive, and transflective LCDs differ in how they use ambient light and backlighting. This guide explains their working principles, key trade-offs, and how to select the right LCD architecture for changing lighting conditions.

LCD display devices use different combinations of addressing methods, liquid-crystal modes, TFT backplanes, backlights, and interfaces. This guide explains the main LCD technologies, how they relate to each other, and how to select a suitable LCD configuration for industrial, medical, automotive, and other applications.

Explore FANNAL's latest TFT-LCD modules and PCAP touchscreens at the 5th Global Digital Trade Expo (GDTE) in Hangzhou, highlighting advanced industrial HMI and optical bonding solutions.

Optical bonding adhesives use different resin systems to provide optical clarity, adhesion, flexibility, and environmental resistance in display assemblies. This guide explains acrylic, silicone, epoxy, and other optical bonding materials, their key properties, and how to select a suitable material for different display applications.
