How to Choose a Display?
Display
One-size does not fit all
IPS (In-Plane Switching) offers TV-like quality viewing, it is not best for dark room operations.
TN offers fastest response time but has gray-inversion and poor “directional” viewing experience.
Color
Vivid color is perceived quality, Color depth determines true color.
Color Gamut is an important factor to content creator. IPS has the highest color gamut - a large range of colors available in color reproduction. Wide-gamut RGB color allows LCD displays more lifelike colors.
Backlight
Brightness enhancements such as high-bright film and backlight are standard for outdoor applications.
Proper backlight thermal design and panel selection are essential to avoid solar clearing (panel darkening), mura (clouding) and other unwanted optical artifacts in the field.
Contrast
Contrast ratio is critical to readability. Contrast ratio of VA (Vertical Alignment) is highest which is between 3000 to 6000:1 compared to most IPS and TN at 1000:1.
Contrast ratio of emissive displays are measured in total darkness, actual ratio is lower depending on reflection of light from display surface.

How to Choose a Touch?
Technology
Projected Capacitive, IR, Resistive, SAW
Projected Capacitive (PCap) is ubiquitous.
Selection between GFF, GF, GG2 and GG depends on weight, thinness and cover decorative designs
Resistive is low cost but offer single touch.
Glove
PCap with superior high Signal and Noise Ratio (SNR) touch controller is ideal for glove operations.
Field Application Support is available in fine tuning devices to accept multiple inputs such as fingers, stylus, latex or thick work gloves.
Contaminates
Oil, salt-water, sand affect PCap touch accuracy. Industrial design consideration must be given at the beginning.
Resistive touch is an option however it has lowest image clarity. Also, outer polyester film is vulnerable to damage from sharp objects.
Surfaces
9H surface hardness for glass front solution is available. LCD sometimes are bonded with PET to pass drop and safety tests.
Other front panel materials include Plexiglas, polycarbonate and PMMA to address flammability, safetly and weight concerns.

Shock & Vibration
Silicone is soft which enhance external shock and vibration
Reduced Parallax
Touch deviation is a major user interface headache, optical bonding reduced parallax
Reflection
Reduced internal reflection light loss to achieve better optics
Condensation
Air gap elimination to avoid possible condensation and dust in the viewing areas
Clarity
Reduced sunlight reflection to improve contrast
