IPS TFT Displays from Relec Electronics

IPS (In-Plane Switching) technology was designed to solve the main limitation of conventional TN (Twisted Nematic) TFTs, i.e. restricted viewing angles and grey scale inversion when viewed away from the preferred viewing direction. Instead it offers a complete viewing angle from any direction. IPS involves arranging and switching the alignment of the crystal molecules between the glass substrates, this change reduces the amount of light scatter in the matrix.  The benefits of wide viewing angles is not just having the perfect colour balance from every viewing point, but also allowing the LCD to be mounted in either landscape or portrait orientation.

The newest offering in Relec’s displays portfolio comes from our partner, DigiWise.  This is a range of 7” TFTs that incorporate IPS technology and a very high resolution of 1024×600, built to the higher standards required for industrial applications as achieved by our other LCDs.  Further features & optical performance of this range are:

• 7” 1024 x 600 (WSVGA) resolution
• Active area dimension of 154.21 x 85.92mm
• 6-bit LVDS interface
• Wide operating temperature range: -20°C to +70°C
• 800:1 contrast ratio
• IPS technology for complete viewing angles
• Brightness level options: 600 cd/m² or 1500 cd/m²
• Anti-glare surface treatment
• Long life LED backlight: up to 70k hours

There are two different options available in the 13-070XILB0G, both units offer all the above features, with the only difference being the level of brightness. The 13-070XILB0GH1-S has a brightness level of 600 cd/m² suited to most indoor and ambient light environments; whereas the 13-070XILB0GH6-S has an extremely high brightness of 1500 cd/m² aimed at outdoor applications and direct sunlight environments, such as marine, drone surveillance and portable instrumentation.

Both of these new modules are available with various options that can further enhance the displays performance depending on your application. Options such as:

• Touch panels, either resistive or projective capacitive
• Optical Bonding for improved ruggedness & daylight viewing
• Surface treatments for: Anti-fingerprint; Anti-bacterial; Anti-glare
• Conductive mesh to enhance EMC immunity
• Custom interface cards for connecting directly to a PC, with all cables
• Thick cover glass for additional protection & the option of custom printing the glass
