Roll-to-roll systems are taken notice as manufacturing process of flexible display which is expected to next generation display. These systems could be used in converting systems. Register error is the one of the most important problem in roll-to-roll flexible display systems. So, the technique of register control must be researched and developed steadily. This paper presents a mathematical model of register error. And the dynamics of register error is simulated under various conditions. Register error is affected by both roll velocity and tension between the front and back span. And the induced register error in arbitrary span generates another register error in next span.

Register control of roll-to-roll printing system for printed electronics requires accurate measurement of register errors. The register marks used for the recognition of patterns position between layers have inherently defects due to low printability of register marks themselves, which brings out inaccurate register accuracy and consequently low performance of printed electronics devices. In this study, the compensation methods for the unrecognized or missing register data are proposed to improve the recognition and consequently the control performance of register accuracy in roll-to-roll printing equipment. The compensation methods using the prior data and the linear interpolation are proposed and compared with the case without compensation for the simulation as well as experiment. Only the linear interpolation method could successfully compensate the missing data and consequently improve the register control performance. We should apply the compensation process of the register errors to improve the register control accuracy in the roll-to-roll printing equipment.

In R2R process, to guarantee mobility of printed electronic material on flexible substrate, optimal drying or curing time is required. Therefore, operating speed is restricted to low level in R2R printed electronic system. The register error that affects the mobility of printed conductive pattern on flexible substrate can be increased, because tension transfer phenomenon depends on time constant that is evaluated from operating speed and a span length of R2R printed electronic system. In this paper the relationship between register error and settling time of tension disturbance is analyzed. To minimize the register error in R2R printed electronic system, the advanced controller was proposed. Through transfer functions of the second-order system with tension model of a span and with desired maximum overshoot and settling time, the advanced controller that can yield minimizing the register error was derived. Simulation results demonstrate the compensation of tension disturbance within the time constant and the effectiveness of the proposed advanced controller for minimizing the register error.

Recently, it is concentrated on productivity improvement in high speed operation by converting industries. Register error is becoming the one of the most issued problem. Moreover register control is the key to product flexible displays through roll-to-roll systems. This paper presents a derivation of register error modeling. And the dynamics of register error is simulated under various conditions. Register error is affected by both roll velocity and tension between the front and back span. And dynamics of register error is to be an interaction in succeeding spans.
