Description

A kind of charactron with touch function

Technical field

The utility model relates to charactron field, especially a kind of charactron with touch function.

Background technique

Charactron, due at low cost, easy to use and developmental research is mature, though liquid crystal display popularize now still So deep welcome by market, charactron is all on the computer board for need to be assemblied in client, because of existing number all the time Pipe, only has the function that simple luminous, control field is shown, user still stops the interaction control mode of charactron In the way of key control, such as by the way that by the opening/closing of key control charactron, function shows switching etc., it is not integrated with touch or only The function of vertical control display.The charactron of integrated touch or integrative display control, but touch signal have been gradually appeared in the market Transmission and display control also need client computer plate to handle.Because just there is PCB in charactron itself, client computer plate It is to be made of PCB, thus causes waste, and also make troubles in exploitation.

Summary of the invention

For overcome the deficiencies in the prior art, the utility model provides a kind of charactron with touch function.This is practical Technical solution used by its technical problem of novel solution is:

A kind of charactron with touch function, including shell, touch electrode and the intracorporal PCB component of shell, the PCB group It is provided with LED, input/output interface, the chip with touch sensible and LED driving function on the PCB of part, is set on the shell It is equipped with pad pasting, the input/output interface of the PCB component is arranged in PCB in the following, sealing in the shell by casting glue PCB, input/output interface pass through casting glue and stretch out shell.

As a preference, it is provided with touch electrode on the PCB of the PCB component, wherein the touch electrode surrounds LED is arranged on PCB.

As a preference, display silk-screen is provided on the pad pasting, the pad pasting is arranged with touch electrode, described Tail band is additionally provided on pad pasting.

As a preference, the PCB is equipped with tail band socket, the touch electrode by tail band, tail band socket with Chip connection.

The beneficial effects of the utility model are: this charactron integrated level is high, charactron can individually complete display board All working meets the general requirment of client, without individually exploitation display board, saves a pcb board, overall plan is more Cost is saved, cooperates burning chip program, realizes different control modes, the control of input/output interface and client can also be passed through Unit processed interaction, and touch electrode, chip are all potted in charactron has Water-proof and oil-proof, oxidation resistant specific, will not It is influenced by external environment.

Detailed description of the invention

The present invention will be further described with reference to the accompanying drawings and examples.

Fig. 1 is a kind of structural schematic diagram of embodiment of the utility model；

Fig. 2 is a kind of top view of embodiment of the utility model；

Fig. 3 is the structural schematic diagram of the utility model another embodiment.

Fig. 4 is the top view of the utility model another embodiment.

Specific embodiment

It is with reference to the accompanying drawings and embodiments, right in order to which the objects, technical solutions and advantages of the application are more clearly understood The utility model is further elaborated.For the thorough explanation present invention, some spies can be related in following description Determine details.And in these no specific details, the invention can still be realized, i.e., the technical staff in fields uses this These of place describe and state that the others skilled in the art into fields can more effectively introduce their work essence.

Referring to Fig.1, Fig. 3, a kind of charactron with touch function, including the PCB in shell 1, touch electrode and shell 1 Component 2 is provided with LED3, input/output interface 4 on the PCB of the PCB component 2, with touch sensible and LED driving function Chip 5 is provided with pad pasting 6 on the shell 1, and the input/output interface 4 of the PCB component 2 is arranged in PCB in the following, the shell PCB is sealed by casting glue in body 1, input/output interface 4 passes through casting glue and stretches out shell 1.

5 inside burning of chip has program, can write according to the requirement of client, realizes personalized demand.Chip 5 is There is the singlechip chip of touch sensible and LED driving function simultaneously, such as close the band LED/LCD driving function of safe (HOLTEK) Touch control key Flash single-chip microcontroller: BS82B12A-3/BS82C16A-3/BS82D20A-3.LED driving function can also pass through journey Sequence realizes that most touch chips can realize the function in this way using common I/O port.

Input/output interface 4 includes except power supply and ground, and input/output interface 4 further includes having in I2C, UART, SPI A kind of or several digital interface.It is also possible to and client's self-defining digital signal exchange way.In addition, input and output connect Mouth 4 further includes having common I/O port, individually controls the function element on the computer board connecting with charactron.In addition, input and output connect Mouth 4 further includes the burning interface for having chip, realizes the functions such as program upgrading, the modification of client.

In actual use, which be assemblied in below the control panel of consumer product, the icon on charactron It is corresponded with position controllable on control panel.When corresponding icon on manpower touch control panel, touch electrode is generated Capacitance change signal, i.e. touch signal can be according to cores after sensing corresponding touch signal with the chip of touch electrode connection The logic of 5 internal program of piece, controls lighting and extinguishing for LED3, while by the state of the touch signal sensed or chip 5 itself It is sent in the form of digital signal input/output interface, client computer can also be received by input/output interface 4 Information on plate, to control lighting or extinguishing for LED3.

Referring to Fig.1, it is provided with touch electrode on Fig. 2, the PCB of the PCB component 2, wherein the touch electrode surrounds LED3 is arranged on PCB, and in actual use, the touch electrode is the induction copper foil 9 on the PCB, and this design touches Electrode is very close at a distance from chip 5, and capacitance interference falls below minimum, loss of signal minimum.
