Then, measure the output voltage when each intersection of the 10mm lattice enclosed by A and B which are located only a certain distance inside the visible area is pressed as shown in Fig. 2. 10mm Y axis 5V A 10mm X axis Bus bar Transparent electrode B Fig. 1 Fig. 2 Plot the output voltage for each measurement position as shown in Fig. 3, and label the difference between the voltage value on the lattice enclosed by A and B and the output voltage at the same position as (Ex, Ey). Linearity is defined as the ratio between (Ex, Ey) and the potential difference between A and B (EABx, EABy). Transparent tablet linearity (X) = (Ex/EABx) x 100% Transparent tablet linearity (Y) = (Ey/EABy) x 100% EBX EBY Measurement value Ex Ey EAX A Measurement value B Measurement position EAY A Measurement position B Fig. 3 - 16 - ACX709AKM Linearity Measurement Connect wiring as shown in Fig. 4, and use the maximum value of the error absolute values when each intersection of the lattice shown in Fig. 5 is pressed as the measurement value. 1 (Y) 4 (X) 3 (Y) 2 (X) 1 (Y) V 4 (X) 3 (Y) 2 (X) V DC5V DC5V Fig. 4 Fig. 5 - 17 - ACX709AKM [Separate Sheet 2: Chattering Measurement Method] * Measuring equipment: HIOKI 8802 MEMORY Hi CORDER * Measurement conditions: Measurement voltage: 5V Test resistor: 100k Switching operation: Holding a R8 silicon rubber rod, perform on and off operation behavior with the same load and speed as normal finger input. Rise, fall time setting: Rise: When the switch changes from off to on, the voltage at both ends of the transparent tablet in the measurement circuit shown below follows a curve such as that shown in the chart below. The rise time is the time from 10% to 90% of the stable measurement voltage. Fall: When the switch changes from on to off, the voltage at both ends of the transparent tablet in the measurement circuit shown below follows a curve such as that shown in the chart below. The fall time is the time from 90% to 10% of the stable measurement voltage.

The load at which the voltage value stabilizes is the operating force for that point. For pen operation, use a R0.8 Polyacetal pen. Tension gauge R8 Hs60 silicon rubber Tablet Finger input measurement Tension gauge Polyacetal pen (R0.8) Tablet Pen input measurement - 19 - ACX709AKM [Separate Sheet 4: Notes on Handling] This touch panel is designed for use in standard applications (OA and other office equipment, industrial and communications-related equipment, consumer use equipment, etc.). Avoid use in applications where malfunction or misoperation may pose the risk of direct harm to people, or for special applications (aerospace, nuclear power control, medical life support, etc.) which require extremely high reliability. Touch panel a) Do not rub or press on the touch panel with sharp blades or other pointed objects. b) Do not excessively fold or bend the touch panel. c) When storing the touch panel, use a packing box and store within the recommended storage temperature range. Also make sure that an excessive load is not applied to the touch panel in the stored condition. d) Avoid storing or using the touch panel under conditions exposed to water and organic solvents, or in an acidic atmosphere. e) Avoid using the touch panel in locations exposed to direct sunlight. f) Do not peel apart or disassemble the touch panel. g) Do not hold the touch panel by just the tail portion; hold the panel glass itself. h) If the touch panel becomes dirty, wipe it clean using a cloth moistened with a neutral detergent or alcohol. Should any chemicals adhere to the touch panel, wipe them off immediately in a manner that does not pose an effect to the human body. i) The glass edges are not beveled, so be careful not to cut yourself when handling the touch panel. Structure a) The environmental, mechanical and electrical characteristics and other specifications are guaranteed only for the input area. b) Condensation forming inside the touch panel does not indicate a malfunction. Condensation will disappear naturally as the touch panel approaches room temperature, but avoid use in the condition where condensation has formed as this may result in malfunction. Electrical specifications and software a) Contact resistance occurs in the conduction between the upper and lower electrodes, and this contact resistance changes according to the finger or pen pressure. Design the software so that data is loaded after the contact resistance stabilizes. b) There are always individual differences in the resistance between pins of analog resistor film type touch panels, and this resistance may also change over time or due to the environment. When designing the software, be sure to provide calibration functions to align the display position with the input position. c) Analog resistor film type touch panels have a structure such that when two points are pressed at the same time, a dot is judged to have been input at the center of the line connecting those two points. Therefore, do not compile software that requires two-point input. d) When drawing with pen input, the line may be broken when the pen passes over a dot spacer. Therefore, corrective functions should be included in the software. - 20 - ACX709AKM [Separate Sheet 5: Notes on Mounting] (1) Bezel tip Make sure the bezel tip falls between the input area and the transparent area. If the bezel tip extends into the input area, when the bezel is pressed the tip may press on the touch panel and result in input. (2) Gap between the bezel and the touch panel Provide a gap of approximately 0.5mm between the inside of the bezel and top surface of the upper electrode of the touch panel. A narrow gap between the bezel and the upper electrode of the touch panel may result in unanticipated input. (3) Use of buffer materials When installing buffer materials between the inside of the bezel and the upper electrode of the touch panel, provide a certain amount of leeway to absorb differences in expansion and contraction between the bezel and the upper electrode due to temperature changes. If the buffer materials are firmly clamped, they may be unable to fully absorb the expansion and contraction, which may cause warping or deflection of the upper electrode of the touch panel, possibly affecting both the appearance and performance of the touch panel. In addition, be sure to insert the buffer materials to the inside of the insulated area. (4) Tolerance The touch panel and the tail dimensions have tolerances of 0.2 to 0.3mm, so be sure to provide leeway of this amount between the case and the connector. 5) Tail bending Do not use a structure where the tail is strongly clamped, bent sharply at the base, or otherwise subject to stress due to case pressure or other factors. Otherwise, insulation defects or disconnected circuits may result. (6) Mounting the touch panel Be sure to use a structure that supports the touch panel from the bottom such as by adhering the touch panel to the display. If the structure adheres the inside of the bezel to the upper electrode of the touch panel, the joint between the upper and lower electrodes will be subject to stress and easily damaged. - 21 - Bezel Input area Transparent area Bezel 0.5mm Upper electrode Bezel Buffer material Insulated area Upper electrode 0.2 to 0.3mm Case Tail Bezel Display ACX709AKM (7) Input prohibited area The area 2mm to the inside from the insulated area has a structurally weak durability. Particularly if this area is pressed during pen input, the film may stretch and be damaged, so make sure the bezel opening does not extend into this area. (8) Ventilation holes Some touch panels have ventilation holes to equalize the internal and external air pressure. Be sure not to block these ventilation holes when mounting the touch panel. In addition, moisture accumulating near ventilation holes may seep into the touch panel, so take care to prevent moisture from accumulating. Also avoid situations where pressure from inside the equipment causes the upper film of the touch panel to bulge.
