5. The information handling system of claim 3 , wherein the orientation sensor is selected from a pressure sensor and a strain sensor.
6. The information handling system of claim 3 , further comprising:
a basic input/output system to communicate with the orientation sensor, the basic input/output system to receive the signal, and to determine, via a processor, an angle between the first and second display platforms based on the signal.
7. The information handling system of claim 1 , wherein the first region is located proximate to a hinge connecting the first and second display platforms of the information handling system.
8. The information handling system of claim 1 , wherein the first region includes:
a plurality of sub-regions, a hardness level of each of the plurality of sub-regions alternates from a high hardness level to a low hardness level.
9. The information handling system of claim 8 , wherein the high hardness level sub-regions are approximately equal to the third hardness level.
10. An information handling system comprising:
a flexible display screen having first and second surfaces, and a first hardness level;
first and second display platforms, the flexible display screen movably mounted to the first and second display platforms along the second surface; and
a coating in physical communication with the first surface of the flexible display screen, the coating including:
a first region of the flexible display screen including a plurality of sub-regions, a hardness level of each of the plurality of sub-regions alternates from a high hardness level to a low hardness level, wherein the high hardness level and the low hardness level are both greater than the first hardness level of the flexible display screen; and
at least one sub-region having a third hardness level, the third hardness level being different than the high hardness level, low hardness level, and the first hardness level.
11. The information handling system of claim 10 , wherein the hardness level of each of the sub-regions varies based on a thickness of the sub-regions.
12. The information handling system of claim 10 , wherein the hardness level of each of the sub-regions varies based on a material composition of the sub-regions.
13. The information handling system of claim 10 , wherein a transition of one of the sub-regions to the next is undetectable by a human finger is based on a width of each of the sub-regions.
14. The information handling system of claim 10 , further comprising:
a cover in physical communication with an edge of the first display platform opposite of the flexible display screen and an edge of the second display platform opposite of the flexible display screen, the first region having a sub-region having a fourth hardness level, the fourth hardness level being greater than the first hardness level.
15. The information handling system of claim 14 , further comprising:
an orientation sensor located within the cover, the orientation sensor to detect flexing of the cover, and to provide a signal indicating an amount of flexing to the information handling system.
16. The information handling system of claim 10 , further comprising:
a basic input/output system to communicate with the orientation sensor, the basic input/output system to receive the signal, and to determine, via a processor, an angle between the first and second display platforms based on the signal.
17. A method for providing a coating on a flexible display screen of an information handling system, the method comprising:
applying a first coating layer of a coating to a first surface of the flexible display screen, wherein the flexible display screen has a first hardness level and the first coating layer on the flexible display screen has a second hardness level greater than the first hardness level;
applying a mask on top of the first coating layer;
applying a second coating layer of the coating to the first coating layer, wherein the mask prevents the second coating layer from being applied to a masked region of the first coating layer where the mask is applied, wherein the second coating layer with the first coating layer in unmasked regions has a third hardness level greater than the second hardness level;
removing the mask from the coating;
movably mounting the flexible display screen to first and second display platforms along a second surface; and
operatively coupling a cover to a back surface of the first display platform and the second display platform opposite of the flexible display screen, the cover including a cover region having a fourth hardness level being greater than the first hardness level.
18. The method of claim 17 , wherein the mask further prevents the second coating layer from being applied to particular strips of the first coating layer within a region aligned with a hinge.
19. The method of claim 17 , wherein the wherein the mask prevents the second coating layer from being applied to a plurality of sub-regions of the first coating layer within a region aligned with a hinge.
