We propose a new tactile display, which stimulates each type of mechanoreceptors separately. We call these stimuli "tactile primary colors" after three primary colors(RGB)in vision. To realise this, we use electrical current from skin surface and activate nerve inside. Although there have been many works on electrocutaneous displays, most of them stayed ad-hoc system, which could only generate strange "electrical feeling". We propose two methods as follows. One is to use array electrodes that are properly weighted. The other is to use anodic current stimulation as well as cathodic current. We developed and tested experimental system with seven array electrodes. Qualitative results supported that the designed stimuli succeeded in activating desired mechanoreceptors' axons. Finally we combined them and generated sensation of elasticity, touch and movement.
