## Abstract

A system and method for driving a multi-layer transparent display, the multi-transparent display including a first transparent display layer and a second transparent display layer is provided. The system includes an input module to receive a stimulus to present content via the multi-transparent display; a display module to determine whether the content is presented via the first transparent display layer or the second transparent display layer; and a layer driver to determine, in response to a condition, whether the content is displayed via the first transparent display layer or the second transparent display layer.

## Claims

### Claim 1

A method for driving a multi-layer transparent display, the multi-transparent display, implemented in a vehicle's instrument cluster, including a first transparent display layer and a second transparent display layer, comprising:
receiving a stimulus to present content via the multi-transparent display;
determine whether the content is presented via the first transparent display layer or the second transparent display layer; and
detecting a dangerous road condition via a forward looking sensor;
switching whether the content is displayed via the first transparent display layer or the second transparent display layer in response to a condition, the condition being defined as an indication that the vehicle is approaching the detected dangerous road condition;
wherein the switching further comprises repeatedly switching the content from the first transparent display layer to the second transparent display layer, and vice-versa, until an indication is received to stop the switching.

### Claim 2 (depends on 1)

The method according to claim 1, wherein the determination further comprises, determining whether the content is presented via the first transparent display layer or the second transparent display layer based on a lookup table, and the lookup table includes a corresponding priority associated with the content.

### Claim 3 (depends on 1)

The method according to claim 1, wherein the switching further comprises, switching the content via the first transparent display layer and the second transparent display layer at a predetermined rate.

### Claim 4 (depends on 1)

The method according to claim 1, wherein in response to engaging a selection option, switching the content presentation from the first transparent layer and the second transparent layer.

### Claim 5 (depends on 1)

The method according to claim 1, wherein the first transparent layer and the second transparent layer overlap each other.

### Claim 6 (depends on 5)

The method according to claim 5, wherein the multi-transparent layer is embedded in an automobile.

### Claim 7 (depends on 6)

The method according to claim 6, wherein at least one of the first transparent layer or the second transparent layer is capable of touch-based detection.

### Claim 8 (depends on 7)

The method according to claim 7, wherein in response to a second content item being received by the input module, determining whether the second content item's priority is higher or lower than the content, and displaying the second content item via the first or second transparent layer based on the determination.
