Problems solved by technology

Therefore, even if a built-in capacitive touch sensor is provided in the display device, there is still a problem that the change in capacitance caused by the user's touch cannot be sensed due to the back electrode, resulting in erroneous operation.
The capacitance is discharged to the outside through the back electrode, so the touch cannot be recognized
[0007] Therefore, it is necessary to solve the problem of unrecognizable touch caused by the back electrode

Embodiment

[0057]0.6 g of PEDOT:PSS solution and 15 g of polysilazane solution were added to a solvent containing a mixture of 39.4 g of water, 5 g of acetylacetone, 20 g of isopropanol, and 20 g of propylene glycol methyl ether to make a composition. The resulting composition was stirred for about 24 hours to well disperse the PEDOT:PSS and polysilazane in the solvent. Next, the prepared composition was loaded into a slit coater, and then coated on a glass substrate. Thereafter, the glass substrate was annealed in a chamber at a temperature of 140° C. for about 10 minutes, thereby removing the solvent. Accordingly, a back electrode formed of PEDOT:PSS and polysilazane was formed on the glass substrate.

[0058] The water vapor permeability WVTR of the as-prepared back electrodes over time was measured and shown in image 3 middle. In addition, the surface resistance of the back electrode over time under high temperature conditions of 80°C was measured and shown in Figure 4 middle. ...

Abstract

A conductive coating composition includes 0.1 to 10 parts by weight of a conductive polymer, 5 to 30 parts by weight of polysilazane, and 30 to 60 parts by weight of a solvent.

Description

[0001] This application claims priority from Korean Patent Application No. 10-2013-0033294 filed on Mar. 28, 2013, which is hereby incorporated by reference for all purposes as if fully set forth herein. technical field [0002] Embodiments of the present disclosure relate to conductive coating compositions. More particularly, the present disclosure relates to a conductive coating composition for manufacturing a transparent conductive film used in a display device and a display device including the composition. Background technique [0003] Recently, various input devices such as keyboards, mice, trackballs, joysticks, and digitizers have been used to interface users with home appliances or various types of data communication equipment. However, using an input device causes inconveniences such as learning how to use the input device and taking up space. Therefore, there are difficulties in increasing the integrity of the product. Therefore, the demand for a convenient and ...
