The picture receiving unit is configured to receive picture data and transmit the picture data to the scan needle. The driving unit is configured to perform a picture scanning process by moving the scan needle to scan in a vertical direction relative to the first surface of the picture display screen at a predetermined frequency. The scan needle is configured to emit light, representative of the picture data, to the first surface of the picture display screen to project image lines, each image line being projected by the scan needle during the scan. The picture display screen is configured to receive the emitted light on the first surface and display an image comprising the image lines on the second surface.

An electronic device includes a display panel and image processing circuitry.
