In this embodiment, the first frame body 16 further covers a touch panel 162 , and the touch panel 162 is disposed on the first substrate 12 .

Next, please refer to the third figure to describe the structure of each first pixel unit 14 in the display 10 in detail. The first pixel unit 14 includes a second substrate 140 and a first colloid 141 . The second substrate 140 is electrically connected to the device. There are at least one ultraviolet light emitting diode 142, at least one red light emitting diode 144, at least one green light emitting diode 146 and at least one blue light emitting diode 148, and the ultraviolet light emitting diode 142, the red light emitting diode 142 The arrangement of the light emitting diodes 144 , the green light emitting diodes 146 and the blue light emitting diodes 148 is arranged on the second substrate 140 in the form of sub-pixels, and the rows are arranged in a rectangular shape.

The second substrate 140 is electrically connected to the first substrate 12 so that the control command output by the control device 20 can be transmitted to the second substrate 140 through the first substrate 12 to control the ultraviolet light emitting diodes 142 and the red light emitting diodes 144. The green light emitting diode 146 and the blue light emitting diode 148 emit light. In this embodiment, the ultraviolet light emitting diodes 142 , the red light emitting diodes 144 , the green light emitting diodes 146 and the blue light emitting diodes 148 are integrated and installed in one with sub-millimeter light emitting diodes.
