Abstract
The present invention relates to a display control device with a double-direction interface, which comprises a buffer, a decoder, a double-direction transmitter and a controller. The present invention is used in a communication device, receives data provided by the communication device to display the data on a display, and can also transmit the received data to other circuits for use.
Description
The present invention relates to a kind of control device of display, particularly a kind of display control apparatus with bidirectional interface.
The known communication device, as phone, the control of its display mostly is microprocessor (Micro Processor), thus, just must there be tens of legs to link up control between microprocessor and display, just must be connected between display and microprocessor, so increase the complexity of circuit and the instability of circuit with bus.
The applicant once proposed a Taiwan and applies for solving the problems referred to above No. 80214375, its calcspar as shown in Figure 1, comprise: a dialer 1, a LCD driver 2 and a LCD 3, wherein the interface of 1 of LCD driver 2 and dialer is a kind of unidirectional interface, be after the data (time, date, timer) of dialer 1 output are passed to display driver 2, display driver 2 can't be passed to these data extraneous other circuit and use, and so will limit the property applied flexibly of LCD driver 2.
Fundamental purpose of the present invention is to provide a display control apparatus with bidirectional interface, it can be passed to internal data again other circuit and use, and has increased the property applied flexibly of controller, and only with two-lines, do not need a bus, data can be passed to other circuit and use.
The present invention relates to a kind of display control apparatus with bidirectional interface, it is used in the communication device, can receive the data that this communication device provides and makes this data presentation in a display, also the data that received can be sent to other circuit to use; Comprise: an impact damper, in order to store the data that this communication device provides, when it goes out stored data transmission, and without detriment to the integrality of its inner former deposit data; One demoder is electrically connected on this impact damper, can receive the data of this impact damper, and with its decoding, and with this data presentation in this display; One two-way transmitter is electrically connected on this impact damper, provides this impact damper a path that interior data is transferred to this remaining circuit; One controller is electrically connected on this transmitted in both directions device, and whether the ON/OFF of this transmitted in both directions device of may command should use to other circuit this data transmission to determine this impact damper.
This impact damper is a shift register (shift register); It is its operating clock pulse signal that this shift register uses the clock pulse signal in this communication device.
This communication device also comprises: a timing signal generator, be electrically connected on this impact damper, and this impact damper chronometric data can be provided; One time signal generator is electrically connected on this impact damper, and this impact damper time data can be provided; This timing signal generator of this controller may command and this time signal generator carry signal to give the operation of this impact damper, and this impact damper is exported to the data class of this demoder.
Described other circuit refers to the dialer or the microprocessor of communication device, and described display can be LCD or light-emitting diode display.This display control apparatus with bidirectional interface can be used for a Caller ID system.
The present invention can understand in depth by following accompanying drawing and detailed description.
Fig. 1 is the block schematic diagram of prior art.
Fig. 2 is a preferred embodiment block schematic diagram of apparatus of the present invention.
See also Fig. 2, be a preferred embodiment synoptic diagram of the present invention, the display controller 5 that the present invention has bidirectional interface comprises: impact damper 51, demoder 52, controller 53, transmitted in both directions device 54; Wherein, demoder 52 is connected to a display 1,51 in impact damper is connected to the dialer (Dialer) 2 and timing signal generator (Timer) 3 and clock signal generator 4 (clock) in the communication device (is example with the telephone device), dialer 2 is sent numeric data code and control code into impact damper 51 storages via transmitted in both directions device 54,53 of controllers are complied with these control codes and are determined whether making transmitted in both directions device 54 to provide impact damper 51 1 feedback path f.p. that data sent back to dialer 2, under the situation of one-way transmission, (be that transmitted in both directions device 54 cuts off feedback path f.p.,), control circuit 53 makes impact damper 51 output datas to demoder 52, impact damper 51 stored data have the name from dialer 2, or data such as number, the time data that also has the chronometric data that produced from timing signal generator 3 and clock-signal generator 4 to be produced, controller 53 can determine impact damper 51 should send any data to demoder 52, demoder 52 just can be shown in it display 1 after these numeric data codes are decoded.
When controller 53 is learnt when answering transmitted in both directions by this control code, even this transmitted in both directions device 54 is connected feedback path f.p, make the data in the impact damper 51 can pass dialer 2 again back, use for other circuit.And this impact damper 51 can be a shift register (shift register), display controller 5 extraneous being provided are provided shift register 51 employed time clock, that is from time clock CLK that dialer provided, whenever, promptly import 1 numeric data code through a time clock and give shift register 51, when feedback path f.p is switched on, because time clock CLK number is identical with the phase inverter phase place of forming shift register 51, so rely on the circuit characteristic of shift register, can give external circuitry with original data in shift register 51, still can preserve its inner data.
In sum, the invention provides a display control apparatus with bidirectional interface, with the next impact damper as storage data in the display control apparatus of a shift register, data that can it is inner offer external circuitry again and use, and have increased the property applied flexibly of control device.In addition, the employed time clock of device of the present invention is by being provided by display controller 5 external worlds, so must additionally not add the synchronous circuit of using, escapable cost; In addition, shift register only needs two-lines can transfer data to extraneous the use, and need not use a bus.Certainly, this display can be the display of any kind of, as LCD or light-emitting diode display etc., and the present invention has the dialer or microprocessor use of display control apparatus in cooperating communication system of bidirectional interface, also can be applied in some other separately and need show data parts such as timing time, name, for example Caller ID of telecommunication bureau etc.
The present invention can be changed and be retrofited by those of ordinary skills, yet does not break away from the scope of claims.
