“…A highly efficient color filter is critical in the development of the high-performance LCDs [3,4]. Notably, dyebased color filters have particular technical advantages in regard to their optical properties owing to reduced light scattering due to the small particle size in the film state; this causes color filters and displays to exhibit superior transmittance to pigment-based one [5].…”

Six novel red perylene dyes were synthesized by modifying the bay-and terminal-positions of perylene main body to improve the optical performances of liquid crystal display (LCD) color filters. The absorption properties, solubility in industrial solvents and thermal stabilities of the dyes were examined to evaluate the dyes for dye-based LCD color filter. Mill bases and spin-coated color filters were formulated and fabricated using the synthesized dyes. Transmittance, dye aggregation and thermal stabilities of the prepared color filters were investigated using a color spectrophotometer. Geometric structures of the synthesized dyes were optimized by using Gaussian program. Five of the synthesized dyes showed acceptable optical properties as colorants for LCD color filters. Also, the synthesized dyes and prepared color filters exhibited suitable thermal stability for the application. Furthermore, the prepared color filters exhibited superior transmittances than pigment-based color filters at 650 nm. Their physical properties were closely related with chemical structures investigated by geometry optimization.

“…In the manufacturing process of TFT-LCDs, the fabrication of color filter (CF) is an indispensable step because white lights are the typical light source for the color display. CF is always deposited on a clear glass substrate which typically includes the black matrix, CF layer, overcoat layer, and indium tin oxide film [1][2][3]. In order to obtain CF of good quality, a large amount of purified water is needed as the CF fabricating process uses lots of photo resists, organic solvents, and pigments.…”

A B S T R A C TIn this study, the energy consumption and the operation cost of using the H 2 O 2 /UV process to treat wastewater from the color filter (CF) fabrication were evaluated by the electrical energy per order (E EO ). The results showed that both decolorization and mineralization followed the pseudo-first-order reaction. For the UV power of 13 W, as the H 2 O 2 dose increased from 50 to 150 mg/L, E EO reduced from 26.5 to 12.8 kW h m −3 order −1 for total organic carbon (TOC) and from 11.3 to 5.7 kW h m −3 order −1 for color. That is, by increasing the amount of H 2 O 2 , the electrical energy efficiency became better due to faster reaction as shown by the larger reaction constant k. Moreover, the electrical energy efficiency was better for the removal of color than for the removal of TOC as E EO,TOC > E EO,color . Moreover, irrespective of TOC and color removals, the E EO values for both UV intensities of 13 and 9 W were close to each other, implying that a higher intensity could be applied by saving the operation time. Through the obtained E EO , the achievable optimum costs to treat CF wastewater for reuse were 0.713 US$/m 3 for decolorization and 1.214 US$/m 3 for mineralization.

“…In the CF manufacturing process, the red (R), green (G), blue (B), and black matrix (BM) film patterns are produced by coating, developing, and postbaking of appropriate photo-resists (Pa 2008;Hwang and Shin 2007). The primary materials and chemicals used include alkaline soluble resins, multifunctional monomers, photo-initiators, organic solvents, and pigments (Ji et al 2009); their usages end up with a large amount of wastewater which has to be treated either for meeting the discharge requirements or for reuse.…”

This study evaluated the feasibility of treating color filter effluent by H 2 O 2 /UV pre-oxidation and membrane postseparation for in-house reuse. The effluent qualities were TOC of 5.8-34 mg/L, color of 46-138 ADMI, and conductivity of 1020-3500 μS/cm. Although the RO separation could directly remove TOC, color, and conductivity effectively, the serious fouling problem still existed. Through H 2 O 2 /UV pre-oxidation (UV = 13 W, H 2 O 2 = 200 mg/L), organic and biofouling were inhibited to increase the normalized flux decline from 5% to 77%. That is, H 2 O 2 /UV pre-oxidation could mitigate the permeate flux decline as well as to improve the water quality for water reuse. ARTICLE HISTORY
