1 TipatOr Liquid metal switch (LMS) display technology Avi Fogel

2 Who is behind TipatOr TipatOr emerged from a merger of 2 expert groups in the fields of MEMS and Displays TipatOr technology is in development for over 3 years TipatOr is seeking an investment of $1M for prototype development

3 Display market ~$110B for all display types TVs and smart-phones account for largest market portions Dominant technology is LCD OLED is emerging as next gen technology. Currently applicable only for small displays like smart-phones and watches

4 Display backplan All hi resolution displays are driven by an active matrix made of thin film transistors (TFT) LCD TFT used are a-si, IGZO OLED TFT used are LTPS, Organic TFT, Metal Oxide TFT. LTPS is the dominant technology LCD TFT can not be used for OLED displays

5 What is liquid metal switch (LMS) LMS is MEMS switch used in active matrix for emissive (OLED) displays as TFT replacement LMS turns OLED into the dominant display technology because it makes it the cheapest and most efficient display technology TipatOr will be the largest display brand in a $100B market outperforming all other major players LMS can be manufactured by OLED fabs without any capital investment

6 Liquid metal switch (LMS) structure

7 Smart-phone display Consumes ~40%-50% of smart-phone energy Very poor efficiency Most expensive smart-phone sub system Made of glass = breakable and costly High capital for manufacturing

8 LCD energy loss contributors Polarizer - 50% Color filters - 67% Grayscale rendering - ~60% (White pixel and black pixel consume the same energy) Aperture and optical coupling - 30% A perfect LCD (100% efficient elements) will have less than 5% efficiency

9 Emissive displays - OLED Should be 20 times more efficient than LCD AMOLED smart-phones displays like Samsung s Galaxy are actually not more efficient than LCD Where is the juice?

10 Thin film transistors (TFT) used in active matrix (AM) for emissive displays - OLED Low electron mobility - limited power, very low efficiency Low yield High cost High variations Degradation over time

11 LMS value proposition LMS is deployed as MEMS switch placed between a power source and an OLED pixel Actuation is achieved by changing the shape of a liquid metal micronic droplet. An electrostatic field as low as 1.5V is sufficient Single LMS replaces multiple TFTs and capacitors in display active matrix (AM) pixel cell Last state is preserved, thus LMS is a bi-stable device that does not require refresh

12 LMS value proposition (cont) Zero power loss - 100% efficiency 2000% (x20) efficiency improvement over second best Doubles smart-phone use time between charges No wear High yield, low cost. process can be scaled to any substrate size. LMS-OLED is the cheapest display technology for any display size Mainly metal process applicable to any metal process equipment/tools found in OLED fabs Can be manufactured over flexible/rigid substrates

13 Droplet actuation simulation Droplet end side is clamped with electrode

14 Technology status A POC device was built and tested in a university laboratory Device electrical and mechanical properties measurements matched simulations 2 patents were applied. 1 granted, 1 pending. More are in preparation.

15 POC device actual pictures

16 Business strategy License manufacturing process over glass substrates + driver chips to OLED fabs Develop LMS process for flexible, roll to roll, substrates Launch TipatOr display brand. Manufactured by subcontractors (low cost OLED fab)

17 Project time line 12 months - Prototype backplan 18 months - Prototype with OLED stack and FPGA driver - Marketing ready 24 months - Prototype + Si drivers - 1st customer 30 months - F.C.S 60 months - TipatOr branded plastic displays
