Serial thermal printing light emitting display

Abstract

A serial thermal printing light emitting display is of a different-combination laminated structure composed of a panel, electrodes, an electroluminescent layer and auxiliary function layers. The lattice of the electroluminescent layer or other auxiliary function layers is generated through serial digital thermal transfer printing of an LED serial printing thermal transfer ribbon [LED SP-TTR] (narrow) containing at least one material of the layer directly or indirectly, once or multiple times and in a collocation or multilayer overlay mode, and the lattice can be cross-linked after transfer printing. The display area and display resolution are only limited by the ITO capability, a roll-to-roll (R2R) continuous production process can be adopted more often, and the production process is applicable to the production of super-QXGA or WUXGA full-color displays. The transfer lattice can be generated without a 'mask plate' or 'slot hole'. The process is simplified, and the cost is reduced. The maximum pixel of the display is 2400PPI. Manufacture of a large-size display is no longer limited by the size of an evaporating dish (VTE) or a reaction chamber (OVPD).

Description

Technical field [0001] A display (screen), a digital printing type electroluminescence display. The present application is a serial thermal transfer electroluminescence display. [0002] Serial thermal transfer electroluminescent display [STP-LED: SerialThermalPrintingLightEmittingDisplay] has a laminated structure of different combinations of panels, electrodes, electroluminescent layers [EML] and its auxiliary functional layers. The transfer dot matrix of the light-emitting layer or other auxiliary functional layer is made of LED serial thermal transfer ribbon containing at least one of these layer materials [LEDSP-TTR: LEDSerialPrintingTTR] directly or indirectly, one or more times, juxtaposed [Collocation ] Or superimposed [MultilayerOverlay], serial thermal transfer generation, and cross-linking after transfer [Cross-linkingafterTransfer] option. [0003] The above-mentioned [0002] serial thermal transfer electroluminescence display, including: liquid crystal display [LCD] [AM...

Problems solved by technology

[0031] 3. The laser-induced thermal imaging ribbon and the printing surface are not transferred immediately after point-to-point thermal transfer, but are uncovered after full-scale photothermal scanning. The transfer layer lacks the temperature gradient necessary for thermal transfer. Viscous gradient, not conducive to the reliable and complete transfer of the transfer layer to the printing surface

However, the generation technology of its electroluminescent body lattice is the most complicated etching process: after the inorganic electroluminescent powder "converting material" is mixed with UV photoresist, it is coated on the blue fluorescent layer, and then irradiated by UV light, Forming, and then removing excess material, the subsequent layer is also produced in the same steps..." Inorganic electroluminescent powder has a high particle size and high specific gravity, and the generation of luminous body lattices is difficult to choose from other printing methods, inkjet technology, laser Heat-induced thermal transfer is even more impossible
