This module was designed by our partner O-Film in China.
The O-Film haptic computer trackpad module uses the BOS1901 driver with a piezo actuator. This hardware allows thinner, less complex, better performing and less power consuming trackpads than leading haptic trackpad currently on the market.
Piezo actuators can replicate with extremely high fidelity the tactile feeling of using a mechanical clicking trackpad. Our BOS1901 can also sense when pressure is apply to a piezo actuator, allowing both haptic feedback and pressure sensing capabilities from the same piezo actuator.
Let's see how the O-Film Piezo Haptic Trackpad Module compares to other technologies.
Trackpads with Piezo Haptics are Better
Different computer trackpad technologies comparison. Key advantages of the O-Film Piezo Haptic Computer Trackpad:
- Lower Power Consumption
- Thinner Solution
- Better Haptic Feedback
- Simplier Structure
|Characteristics||Traditional Click Pad||Leading LRA Trackpad||O-Film Piezo Trackpad|
|Thickness (Touch + Haptics)||4 mm||3 mm||<2.8mm|
|Haptic Feedback||No||Yes - LRA (narrow bandwidth)||Yes - Piezo Actuator (wide bandwidth)|
|Pressure Sensing||N/A||Yes - With additional sensing hardware||Yes - With same Piezo Actuator|
|Response Time||> 50 ms||> 20 ms||< 5 ms|
|Power Consumption||N/A||60 mW||5 mW|
|Weight||45 g||65 g||35 g|
The O-Film Piezo Haptic Computer Trackpad Module is less complex thant its mechanical and LRA based counterparts. Using the BOS1901 piezo driver allows pressure sensing without additionnal hardware, making the integration simplier, more reliable and cost effective.
