The Sharp Aquos Phone is waterproof, dust proof, has a 8MP camera, 1.5ghz dual-core processor, and a second "ticker display" that shows time/notifications. We take a closer look at this fascinating device. Find Sharp phones: https://goo.gl/1j9dpb

The IS13SH utilized a dual-screen design to provide information without waking the main panel: 
Main Display: 4.2-inch "New Mobile ASV" LCD with a QHD resolution of 540 x 960 pixels.
Sub-Display: 2.1-inch monochrome "Memory LCD" (56 x 304 resolution) located below the main screen for showing clocks and notifications while the main display is off.

While Sharp's use of a dedicated Memory LCD for an always-on secondary display was relatively rare, they released several models around the same era that shared this hardware philosophy or featured unique dual-display setups.

Models with Secondary "Memory LCD" Displays:
These devices used the same low-power monochrome sub-display technology as the IS13SH to show notifications and clocks without draining the battery.

Sharp AQUOS PHONE IS17SH: This was the direct successor to the IS13SH on the au by KDDI carrier. It maintained the same core concept, featuring a 2.1-inch Memory LCD sub-display located below the main 4.2-inch screen.

Sharp AQUOS PHONE SL IS15SH: A unique slider phone that combined a touchscreen with a physical numeric keypad. While its primary focus was the slider form factor, it utilized a similar sub-display strategy to provide persistent information.

Sharp AQUOS PHONE CL IS14SH: Another slider model from the same generation that focused on a compact design while incorporating Sharp's energy-efficient display technologies for secondary information.

Sharp experimented heavily with other ways to provide "secondary" viewing experiences during this period: 

Sharp AQUOS PHONE IS11SH: A vertical slider focused more on the physical keyboard experience than the sub-display but shared the same "New Mobile ASV" main LCD technology.

Sharp AQUOS PHONE IS12SH: This model featured a glasses-free 3D display and dual rear cameras for 3D photography, offering a different kind of "secondary" visual depth rather than a separate notification screen.

Sharp AQUOS Keitai Series (e.g., 601SH, 805SH): For those interested in the sub-display concept, Sharp's "Keitai" flip phones (ガラホ) almost universally feature a 0.7-inch to 1.0-inch EL sub-display on the outer shell to show the time and caller ID when the phone is closed.

In modern smartphones, Sharp has transitioned away from physical secondary LCDs in favor of Always-On Display (AOD) features on their high-refresh-rate Pro IGZO OLED panels (i.e. Sharp Aquos R9, Sharp Aquos R10).
