Organic light-emitting short-term visual stimulation platform for brain function control

A visual stimulation platform comprising:

• an OLED module comprising an anode electrode and a cathode electrode which are made of a semi-permeable film or a transparent conductive film;
• a controller configured to control an operation of the OLED module;
• and
• a power supply configured to supply operating power to the OLED module and the controller,
• wherein the visual stimulation platform is configured as a wearable device to project light generated from the OLED module to eyes of a user according to control of the controller,
• wherein the controller comprises a wavelength setter, a time setter, a brightness setter, a frequency setter, and a duty ratio setter for light generation of the OLED module,
• wherein the OLED module is configured to generate light in at least one wavelength range of W (white), R (red), or G (green) through the wavelength setter,
• wherein the controller is configured to control:
• a first mode in which light generated from the OLED module stimulates the user's eye, and
• a second mode in which, when the light generation of the OLED module is turned off, a field of view of the user wearing the visual stimulation platform is secured through the OLED module,
• wherein in case of operating in one selected from among the first mode and the second mode, a time set through the time setter has a greater value in the second mode than in the first mode to ensure an equivalent level of visual stimulation in both modes, and
• wherein in case of operating in the second mode, while a light generation on and off frequency driving set through the frequency setter is performed to simultaneously enable visual stimulation and field of view securing:
• a brightness of light during a turn-on period of the OLED module set through the brightness setter has a smaller value in the second mode than in the first mode, and
• at an identical frequency set through the frequency setter, a duty ratio set through the duty ratio setter has a smaller value in the second mode than in the first mode.
