Select the driver library¶
The driver library comes in different versions, based on the screen film and size, and the edition.
Only screens with an iTC driver are supported.
The name of the driver library starts with Pervasive_, then includes the film and ends with the family based on the size of the screen.
Example
Let’s consider the screen with product number CE2271KS094.
Film¶
The film defines the features of the screen, with the associated library.
| Letter | Film | Feature | Update |
|---|---|---|---|
Q |
BWRY |
Black, white, red, yellow | Normal |
K |
Wide |

Fast |
Touch |

Example
The film of the example is K for film Wide.
The name of the driver library starts with Pervasive_Wide.
Tip
For screens non listed here, for example monochrome screens (film C), monochrome screens with embedded fast update (film P) or colour black-white-red screens (film J), refer to the Legacy drivers and library.
