Fabrication and performance evaluation of microfluidic organic light emitting diode

Multi-color microfluidic electrochemiluminescence cells

“…In our previous work, we proposed microfluidic technologies to obtain patterned liquid emitters on a single device [16]. The negative photoresist SU-8-based microfluidic device with a matrix of light-emitting pixels was fabricated using photolithography and heterogeneous bonding technique through the use of amineand epoxy-terminated self-assembled monolayers (SAMs).…”

Recent Advances in Research and Development of Microfluidic Organic Light-Emitting Devices

“…In order to integrate individual multiple liquid OLEDs on one substrate, we fabricated single-m-thick electro-microfluidic devices using MEMS process and heterogeneous bonding technology through the use of amine-and epoxy-terminated self-assembled monolayers (SAMs) [20][21][22][23][24]. Figure 2 shows the design of a prototype microfluidic OLED that consists of a 3 x 3 array of light-emitting pixel in SU-8-based microchannels.…”

“…3. The detailed information could be found in our previous work [20][21][22][23][24]. The ITO-coated glass and PEN substrates were used as the anode and cathode substrates, respectively ( Fig.…”

“…Toward next-generation display, our research group has proposed multi-color microfluidic OLEDs that combined liquid OLEDs with electro-microfluidic devices [20][21][22][23][24][25][26]. The concept of the microfluidic OLED display is shown in Fig.…”

Tunable and flexible solvent-free liquid organic distributed feedback lasers

“…Liquid organic semiconductors also allow for convectional circulation of active materials in microfluidic structure, which can lead to degradation-free characteristics. 5,6 To date, various organic optoelectronic applications including photorefractive devices, 7 organic light-emitting diodes, [8][9][10] dye-sensitized solar cells, 11 and bistable memories 12 have been demonstrated using liquid organic semiconducting materials. The regeneration of the active areas of devices by a simple injection of a fresh batch of materials cannot be achieved in solid-state organic and polymer thin films but was demonstrated in fluidic OLEDs based on a solvent-free liquid semiconducting layer.…”
