Embodiment Construction

[0033] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the associated drawings. Preferred embodiments of the invention are shown in the accompanying drawings. However, the present invention can be embodied in many different forms and is not limited to the embodiments described herein. On the contrary, these embodiments are provided to make the understanding of the disclosure of the present invention more thorough and comprehensive.

[0034] It should be noted that when an element is referred to as being “fixed” to another element, it can be directly on the other element or there can also be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and similar expressions are used herein for purposes ...

Abstract

The invention relates to a transparent conductive film which comprises a base material, an optical adjusting layer and a functional layer. A first surface and a second surface of the base material areeach sequentially provided with an optical adjusting layer and a functional layer, and at least one of the optical adjusting layers is provided with a plurality of particles. Protrusions are formed on the surface of the functional layer through the particles, so that the anti-adhesion effect is achieved. Moreover, in a direction parallel to the surface of the flat portion and perpendicular to thesurface of the flat portion, the sizes of the protrusions are respectively 5-30 micrometers and 0.1-3 micrometers. Therefore, the size in the vertical direction is far smaller than the size in the parallel direction, and the slope of the protrusion is small, and the protrusion smoothly transits to the flat part. Therefore, light reflection, transmission, refraction and the like generated at the protrusion and the flat part are relatively uniform, and formation of an overlarge abrupt change fall is avoided, so that the optical effect of the transparent conductive film is effectively improved.In addition, the invention also provides a touch screen and a thin film resistance strain type pressure sensor.

Description

technical field [0001] The invention relates to the technical field of conductive film materials, in particular to a transparent conductive film, a touch screen, and a film resistance strain type pressure sensor. Background technique [0002] Transparent conductive films are the core components of electronic components such as capacitive touch screens and thin-film resistive strain sensors. With the rapid development of smart terminal technology, the demand for transparent conductive films is also increasing. A transparent conductive film generally includes a base material and intermediate protective layers and functional layers disposed on both sides of the base material. [0003] At present, high-performance transparent conductive films generally use amorphous polymer films as substrates. However, amorphous polymer films are more fragile than crystalline polymer films. When curled into a cylindrical shape, the outermost layers of adjacent transparent conductive films ar...
