Flat panel display with built-in touch panel

摘要

A flat panel display with a built-in touch panel includes a display panel having a lower substrate, an upper substrate, and a plurality of touch sensing patterns on the upper substrate. The plurality of touch sensing patterns includes a plurality of sensing cells on a bottom surface of the upper substrate that faces the lower substrate, a plurality of outer lines on the bottom surface of the upper substrate that connect lines of sensing cells of the plurality of sensing cells along at least one of a first direction or a second direction to a driving circuit, a plurality of connection lines that correspond to respective outer lines on the lower substrate. The plurality of outer lines are connected to the driving circuit via the plurality of connection lines on the lower substrate, and the plurality of outer lines are electrically connected to the corresponding connection lines.

1. A flat panel display with a built-in touch panel, the flat panel display comprising:
a display panel including a lower substrate, an upper substrate, and a plurality of touch sensing patterns on the upper substrate, the lower substrate including a display region and a non-display region, the non-display region defining a periphery of the lower substrate and enclosing the display region; the plurality of touch sensing patterns including a plurality of sensing cells on a bottom surface of the upper substrate that faces the lower substrate, the plurality of touch sensing patterns overlapping the display region on the lower substrate; a plurality of outer lines on the bottom surface of the upper substrate that connect lines of sensing cells of the plurality of sensing cells along at least one of a first direction or a second direction to a driving circuit, the outer lines including first raised portions that face the lower substrate; and a plurality of connection lines that correspond to respective outer lines on the lower substrate, the connection lines including second raised portions that face the upper substrate, wherein: the plurality of outer lines are connected to the driving circuit via the plurality of connection lines on the lower substrate the first raised portions of the plurality of outer lines are electrically connected to the second raised portions of corresponding connection lines, the first raised portions of the outer lines and the second raised portions of the connection lines being only in the non-display region, and the first raised portions of the outer lines being in constant and direct contact with the second raised portions of the connection lines, and step forming patterns between the first raised portions of the outer lines and the upper substrate and between the second raised portions of the connection lines and the lower substrate, heights of the respective step forming patterns being set such that first raised portions and second raised portions are in constant contact with each other.
