| WiViTouch's IR dual-touch screen(two touchpoints) (Size from 17'' to 65'')has two types:
With frame and glass or with frame no glass. You can choose with glass or without glass as you like.
WiViTouch's IR dual-touch screen(two touchpoints) (Size over 65'') usually has no glass. Two reasons:
* The size is too big, there is no glass suit for it.
* Too big size glass installed in the frame, it is easy to be broken in shipping.

| What is IP62, IP65, IP68? |
 |
| The IP Code (or International Protection Rating, sometimes also interpreted as Ingress Protection Rating) consists of the letters IP followed by two digits and an optional letter. As defined in international standard IEC 60529, it classifies the degrees of protection provided against the intrusion of solid objects (including body parts like hands and fingers), dust, accidental contact, and water in electrical enclosures. The standard aims to provide users with more detailed information than vague marketing terms such as waterproof. The digits (characteristic numerals) indicate conformity with the conditions summarized in the tables below. Where there is no protection rating with regard to one of the criteria, the digit is replaced with the letter X.
- IP62 means the touch screen is protected against dust and Dripping water when tilted up to 15°.
- IP65 touch screen is protected against dust and water jet.
- IP68 means a touch screen is protected against dust and continuous immersion in water beyond 1 m.

Solids, the first digit The first digit indicates the level of protection that the enclosure provides against access to hazardous parts (e.g., electrical conductors, moving parts) and the ingress of solid foreign objects.

Dust protected |
Ingress of dust is not entirely prevented, but it must not enter in sufficient quantity to interfere with the satisfactory operation of the equipment; complete protection against contact |
| 6 |
Dust-tight |
No ingress of dust; complete protection against contact |
Liquids, second digit Protection of the equipment inside the enclosure against harmful ingress of water.

| 1 |
Dripping water |
Dripping water (vertically falling drops) shall have no harmful effect. |
Test duration: 10 minutes Water equivalent to 1mm rainfall per minute |
| 2 |
Dripping water when tilted up to 15° |
Vertically dripping water shall have no harmful effect when the enclosure is tilted at an angle up to 15° from its normal position. |
Test duration: 10 minutes Water equivalent to 3mm rainfall per minute |
| 3 |
Spraying water |
Water falling as a spray at any angle up to 60° from the vertical shall have no harmful effect. |
Test duration: 5 minutes Water volume: 0.7 liters per minute
Pressure: 80–100 kN/m² |
| 4 |
Splashing water |
Water splashing against the enclosure from any direction shall have no harmful effect. |
Test duration: 5 minutes Water volume: 10 liters per minute
Pressure: 80–100 kN/m² |
| 5 |
Water jets |
Water projected by a nozzle (6.3mm) against enclosure from any direction shall have no harmful effects. |
Test duration: at least 3 minutes Water volume: 12.5 liters per minute
Pressure: 30 kN/m² at a distance of 3m |
| 6 |
Powerful water jets |
Water projected in powerful jets (12.5mm nozzle) against the enclosure from any direction shall have no harmful effects. |
Test duration: at least 3 minutes Water volume: 100 liters per minute
Pressure: 100 kN/m² at a distance of 3m |
| 7 |
Immersion up to 1 m |
Ingress of water in harmful quantity shall not be possible when the enclosure is immersed in water under defined conditions of pressure and time (up to 1 m of submersion). |
Test duration: 30 minutes Immersion at depth of 1m |
| 8 |
Immersion beyond 1 m |
The equipment is suitable for continuous immersion in water under conditions which shall be specified by the manufacturer. Normally, this will mean that the equipment is hermetically sealed. However, with certain types of equipment, it can mean that water can enter but only in such a manner that it produces no harmful effects. |
Test duration: continuous immersion in water Depth specified by the manufacturer |
