Problems solved by technology

[0004] In the future, electronic equipment will gradually develop towards curved surface design and flexible screen design. However, touch modules made of conventional transparent conductive films are often not suitable for frequent bending.
The production of conductive films in the prior art usually has the following technical problems. The production process is complicated, and the product quality cannot be stably controlled, and the yield rate is low. Restricted, does not conform to the trend of ultra-light and ultra-thin development of existing touch screens, and the cost is high
With the increasingly higher requirements for bending of touch screens, the traditional external touch screen structure design can no longer meet the market demand, and the flexible screen has higher requirements for structural thickness than ordinary screens. Therefore, it is necessary to develop a thin, A flexible touch display with good bending resistance is also necessary

Embodiment 1

[0051] Such as figure 1 As shown, the present embodiment discloses a touch conductive film for a flexible touch display screen, which includes a transparent substrate 1, on which a first UV glue layer 2 is provided, and the first conductive layer 3 is formed by a pattern The conductive material is embossed on the first UV adhesive layer 2 in a plurality of grid grooves; the transparent reinforced insulating support layer 4 is provided with a third UV adhesive layer 5, and the second conductive layer 6 is composed of The pattern embossed on the third UV adhesive layer 5 is composed of conductive materials in a plurality of grid grooves.

[0052] It should be noted that the third UV adhesive layer containing the second conductive layer is arranged on the second UV adhesive layer (reinforced insulating support layer) cured after imprinting, which can greatly improve the first conductive layer and the second conductive layer. Insulation strength between, to avoid the problem of cond...

Embodiment 2

[0095] Such as Figure 4 As shown, this embodiment discloses another touch conductive film for a flexible touch display screen, which includes a transparent substrate 1, a first conductive layer 3 disposed on the transparent substrate, and a second conductive layer 3 disposed on the first conductive layer. Two conductive layers 6, a transparent reinforced insulating support layer 4 is provided between the first conductive layer 3 and the second conductive layer 6, and the second conductive layer 6 is provided on the cured reinforced insulating support layer 4;

[0096] The difference from the first embodiment is that the first conductive layer of the second embodiment is formed of conductive material filled in grid grooves opened on the transparent substrate 1.

[0097] It should be noted that compared with the first embodiment, the second embodiment has the first UV glue layer removed, which is equivalent to a thinner touch conductive film, but the effect of directly imprinting the...

Abstract

The invention discloses a flexible touch display screen which comprises an OLED display layer, and a bonding layer, a touch conductive film, a bonding layer and a hardened protective layer are sequentially arranged on the OLED display layer. The touch conducting film comprises a transparent substrate layer, a first conducting layer, a reinforced insulation supporting layer and a second conductinglayer, and the first conducting layer and the second conducting layer are both of an embedded metal grid structure in a transparent polymer layer to form a capacitive touch layer, wherein the transparent polymer layer is made of bending-resistant high polymer material imprinting glue, and the embedded metal grid structure is formed by curing high-toughness thermosetting conductive slurry; and thereinforced insulating supporting layer is an independently arranged UV adhesive layer. The flexible touch display screen is optimized in structure, low in cost, stable in quality and wide in application scene.

Description

Technical field [0001] The invention relates to the technical field of flexible screens, in particular to the technical field of flexible touch screens. Background technique [0002] OLED display technology has self-luminous characteristics. It is made of very thin organic material coatings and glass substrates. When current passes through, these organic materials will emit light. Moreover, the OLED display screen has a large viewing angle and can save power, so the application is very widely. [0003] Since September 2017, Apple has used OLED panels on its iPhone X products for the first time, making OLED panels gradually become the mainstream of high-end smart devices, and with the continuous development of OLED technology, many OLED manufacturers have successively mass-produced flexible OLEDs screen. For OLED manufacturers, how to implement flexible touch technology on flexible screens will be a new technical issue. [0004] In the future, electronic equipment will gradually de...
