Touch color filter and manufacturing method thereof, touch display panel

Abstract

The invention discloses a touch type colored light filter, and in particular relates to an optical touch type colored light filter. The optical touch type colored light filter comprises a substrate, a first electrode layer which is arranged on the substrate to define a plurality of sub-pixel areas and equipped with an X electrode, a semiconductor layer positioned above the X electrode, a second electrode layer which is positioned above the semiconductor layer and equipped with a Y electrode, and a color resistance layer which comprises a plurality of colored filter units that are respectively distributed in the sub-pixel areas; the Y electrode, the Y electrode and the semiconductor layer between the X electrode and the Y electrode form a photoelectric diode sensing element which is of a sandwich structure; the photoelectric diode is in a reversed stopping state when no strong light irradiates, the sensing element suffers from small current leakage, namely closing state occurs; in case of irradiating by light, the photoelectric diode can generate more than 100 times current, and current flows through the device, namely, opening state occurs. The touch type colored light filter, is simple in manufacturing process, and the sensitivity of light touch can be improved.

Description

technical field [0001] The present invention relates to the field of a color filter, a manufacturing method thereof, and a display panel, and in particular to an optical touch color filter, a manufacturing method thereof, and an optical touch display panel. Background technique [0002] In recent years, with the rapid development and application of information technology, wireless mobile communication and information home appliances, in order to achieve more convenient, lighter and more humanized purposes, many information products have traditional input devices such as keyboards or mice. Switch to using a touch panel as an input device. Among them, the touch LCD panel, as the most popular touch panel, has been widely used in consumer electronic products such as personal digital assistants, smart mobile phones, and satellite navigation. [0003] The existing touch LCD panels are mainly built-in capacitive touch panels as the mainstream products. The integration of touch ele...

Problems solved by technology

Since the ambient light is non-polarized light, only about 50% of the light can pass through the upper polarizer, so it is easy to reduce the touch sensitivity in a dark room

[0005] Furthermore, the touch signal wires of the existing optical touch control and the semiconductor devices of the display array substrate are on the same substrate, and since the touch wires need to be arranged under the condition of ensuring the aperture ratio of the display, the wires of the touch array and the display array The wires are arranged in parallel at close positions, which will inevitably lead to signal coupling and lead to defective products. At the same time, due to the complicated semiconductor manufacturing process, the defective photoelectric switch further reduces the yield rate of the display array substrate. Therefore, mass production It is difficult to improve the yield

In addition, embedding a touch sensor in a pixel reduces the area available for display, which is one of the main causes of image quality degradation
