Definitions
- the present disclosure relates to organic electroluminescent technology, and more particularly to a blue polarizing film, a method of fabricating the same, and a blue backlight and a liquid crystal display device.
- blue light emission In the development of organic electroluminescent devices, how to achieve blue light emission has always been a core issue due to the scarcity of blue light materials. If blue light emission can be achieved, it can further form a three primary color emission with the green and red light emitting materials, thereby obtaining white light emission.
- the blue polarizing film provided by the present disclosure is a multilayer film formed by alternately depositing magnesium aluminum hydrotalcite and tris(8-hydroxyquinoline-5-sulfonic acid) aluminum.
- the multilayer film is 4-10 layers.
- the magnesium aluminum hydrotalcite layer has a thickness of 10 nm to 20 nm; and the tris(8-hydroxyquinoline-5-sulfonic acid) aluminum layer has a thickness of 10 nm to 20 nm.
- the fluorescence spectrum has a maximum emission value of 470 nm to 490 nm.
- the blue polarizing film is obtained by immersing the substrate in a 10 g/L-20 g/L magnesium aluminum hydrotalcite solution for 10 min to 15 min, taking out drying, and then immersing in 3 g/L to 10 g/L.
- 8- The hydroxyquinoline-5-sulfonic acid) aluminum solution is taken out for 10 min to 15 min, and taken out and blown dry, thus completing a cycle, and the multilayer film obtained by the above cycle is repeated.
- the preparation method of the blue polarizing film provided by the present disclosure comprises immersing the substrate in a 10 g/L-20 g/L magnesium aluminum hydrotalcite solution for 10 min to 15 min, taking out and drying, and then immersing in 3 g/L to 10 g/L three (8).
- the hydroxyquinoline-5-sulfonic acid) aluminum solution is taken out for 10 min to 15 min, and blow-dried is taken out, thus completing a cycle, and the multilayer film obtained by the above cycle is repeated.
- the above cycle is repeated 2-5 times.
- a blue light backlight provided by the present disclosure, comprising the blue light polarizing film of any of the above.
- the liquid crystal display device comprises an upper polarizing plate, a color film substrate, a liquid crystal layer, an array substrate, a lower polarizing plate and a backlight, wherein the backlight is the blue light backlight.
- the blue-light polarizing film of the present disclosure has a maximum emission value of 470 nm to 490 nm in the blue light region and a fluorescence anisotropy value of 0.1-0.2, and has polarization characteristics, which can be used for a liquid crystal display backlight, and has both light-emitting characteristics. There is also a polarization characteristic that changes the disadvantages of conventional liquid crystal displays using both a polarizer on the side of the backlight and a luminescent material in the backlight.
- the blue polarizing film of the present disclosure is a multilayer film formed by alternately depositing magnesium aluminum hydrotalcite and tris(8-hydroxyquinoline-5-sulfonic acid) aluminum.
- the film obtained by the alternate deposition method is uniformly dense and since the thickness of the single layer film can be precisely controlled and the thickness of the repeatedly deposited film is controllable, the luminescence intensity of the film can be precisely controlled by controlling the number of layers deposited.
- the blue light material (formed by the tris(8-hydroxyquinoline-5-sulfonic acid) aluminum thin film) used in the alternate deposition method of the present disclosure has a low concentration, and the magnesium aluminum hydrotalcite acts to isolate the two blue light material films, thereby avoiding Fluorescence quenching of blue light materials. Therefore, the more the number of layers of the multilayer film, the more blue light material is deposited, and the higher the blue light intensity.
- the multilayer film is 4-10 layers
- the magnesium aluminum hydrotalcite layer has a thickness of 10 nm to 20 nm
- the tris(8-hydroxyquinoline-5-sulfonic acid) aluminum layer has a thickness of 10 nm to 20 nm.
- the maximum emission value of the fluorescence spectrum of the blue polarizing film is 470 nm to 490 nm, both of which are in the blue light region.
- the blue polarizing film is obtained by immersing the substrate in a 10 g/L-20 g/L magnesium aluminum hydrotalcite solution for 10 min to 15 min, taking out drying, and then immersing in 3 g/L to 10 g/L.
- 8- The hydroxyquinoline-5-sulfonic acid) aluminum solution is taken out for 10 min to 15 min, and taken out and blown dry, thus completing a cycle, and the multilayer film obtained by the above cycle is repeated.
- a blue light backlight of the present disclosure comprising the blue light polarizing film of any of the above.
- the liquid crystal display device comprises an upper polarizing plate, a color film substrate, a liquid crystal layer, an array substrate, a lower polarizing plate and a backlight, wherein the backlight is the blue light backlight.
- Magnesium-aluminum hydrotalcite the structural formula of which is Mg 2 Al(OH) 6 NO 3 LDH ([Mg 2 Al(OH) 6 NO 3 ].xH 2 O), and weighs Mg (NO) according to a molar ratio of 2:1.
- a 3 g/L aqueous solution of tris(8-hydroxyquinoline-5-sulfonic acid) aluminum was prepared with water, and the solution was negatively charged.
- the ITO substrate was immersed in the magnesium aluminum hydrotalcite solution for 10 min, dried and then immersed in a solution of tris(8-hydroxyquinoline-5-sulfonic acid) aluminum for 10 min to blow dry to complete a cycle. The above cycle was repeated 3 times to obtain a blue light polarizing film.
- the magnesium aluminum hydrotalcite and the tris(8-hydroxyquinolin-5-sulfonic acid) aluminum in the blue polarizing film are bonded together by electrostatic action. (The thickness of the magnesium aluminum hydrotalcite and the tris(8-hydroxyquinolin-5-sulfonic acid) aluminum layer was determined by scanning electron microscopy to be 10 nm)
- the wavelength of the excitation light is 360 nm.
- the results are shown in Table 2.
- the maximum emission value of the fluorescence spectrum of the blue polarizing film prepared in this example was 476 nm in the blue light region.
- Magnesium-aluminum hydrotalcite having a structural formula of Mg 2 Al(OH) 6 NO 3 LDH ([Mg 2 Al(OH) 6 NO 3 ].xH 2 O).

- the ITO substrate was immersed in a magnesium aluminum hydrotalcite solution for 15 min, blown dry, and then immersed in a tris(8-hydroxyquinoline-5-sulfonic acid) aluminum solution for 15 minutes to blow dry to complete a cycle. The above cycle was repeated 3 times to obtain a blue light polarizing film.
- the magnesium aluminum hydrotalcite and the tris(8-hydroxyquinolin-5-sulfonic acid) aluminum in the blue polarizing film are bonded together by electrostatic action. (The thickness of the magnesium aluminum hydrotalcite and the tris(8-hydroxyquinolin-5-sulfonic acid) aluminum layer is 20 nm by scanning electron microscopy)
