Description

COF product capable of driving multiple display screens

Technical Field

The invention relates to a COF product capable of driving multiple display screens, and belongs to the technical field of double-screen manufacturing.

Background

Nowadays, mobile phones have become indispensable communication tools in people's daily life, and with the development of mobile phones, comprehensive screens, curved screens and even double screens slowly appear in the market. Due to the screen design, the operation of a consumer can be facilitated, and the experience interest of the consumer in using the smart phone is improved.

The existing mobile phone is generally provided with a display module, when the mobile phone is used for realizing different requirements, the configuration of only one display module is increasingly not suitable for the use of various scenes, and the mobile phone with double screens gradually appears for pursuing the maximization of a display screen and meeting various operation requirements. Therefore, a display module is additionally arranged on the back of the mobile phone, and the two display modules are completely deviated from each other due to the display surface, so that simultaneous display and operation cannot be realized. This has the following disadvantages: 1. as the mobile phone tends to be light and thin, the thickness of the mobile phone is increased by using the dual-mode set to realize the dual-screen mobile phone. 2. The dual-screen mobile phone is realized through the dual-mode set, so that each display screen is driven independently, and the simultaneous driving of two screens cannot be realized.

Disclosure of Invention

In order to solve the technical problem, the invention provides a COF product capable of driving multiple display screens, which can realize that a single IC drives two or more display screens, thereby not only realizing the double-screen requirement of a mobile phone, but also meeting the requirements of simultaneous display and operation of the two screens.

The invention is realized by the following technical proposal, a COF product capable of driving a plurality of display screens,

the COF product is formed by arranging at least two output ends, a drive IC and an input end on the COF; the input end transmits signals to the output end through the driving IC;

the display is provided with a display input end for receiving signals;

the module is bound through the output that will show on input and the COF product, realizes the module.

The preferable scheme of the COF product capable of driving the multiple display screens in the invention is as follows: two output ends, namely an output end I and an output end II, are arranged on the COF; and the output end I and the output end II are respectively connected with an ACF (anisotropic conductive film) at the display input end of the display, so that double-screen display and operation are realized.

The preferable scheme of the COF product capable of driving the multiple display screens in the invention is as follows: the COF product adopts an arc-shaped structure.

The invention has the beneficial effects that: 1. the dual-screen simultaneous driving can be realized, and different experiences are brought to users. 2. The double-screen simultaneous driving is realized, and the utilization rate of driving products is increased. 3. The volume and weight of the end product can be reduced.

Detailed Description

The invention is further illustrated by the following examples and figures.

Example 1

A COF product capable of driving a multi-display as shown in fig. 1 to 3, the COF product is formed by providing at least two output terminals, a driver IC11, and an input terminal 12 on a COF; the input end 12 transmits signals to an output end through a driving IC 11;

a display 20 on which a display input 21 for receiving signals is provided;

the module 30 is implemented by binding the display input terminal 21 with the output terminal on the COF product.

Two output ends, namely an output end I13 and an output end II 14, are arranged on the COF; and the output end I13 and the output end II 14 are respectively connected with the display input end 21ACF anisotropic conductive film of the display 20, thereby realizing double-screen display and operation.

The COF product adopts an arc-shaped structure.

The working principle is as follows: the invention can drive the input end 12 of the COF product of the multi-display screen to be connected with the mainboard, and the input end 12 is transmitted to the output end I13 and the output end II 14 through the drive IC, thereby driving the display screen.
