Foot transmission display signal, while being powered using VBUS power supply.
There are two Full Featured USB-C (TYPE-C) interfaces by the present invention, comprising: power supply, agreement communication, USB2.0, video
Signal), the function of the two signaling interfaces is completely the same.
Workflow explanation:
Equipment (computer, mobile phone, plate) is connected to one of TYPE-C interface, and VBUS first provides fundamental power supply to association
Chip power supply is discussed, protocol chip and equipment carry out capacity of power communication, request power supply, and equipment provides power supply power supply to display screen,
And USB port switch is controlled, allow the USB port of equipment (computer, mobile phone, plate) to become " uplink port " (host side), this
There is USB-HUB (i.e. USB serial port chip) on the display Driver Card of invention, can support multiple USB devices while connect, together
When equipment can read the EDID of display screen, understand the display capabilities that display screen can be supported, and send out display signal, show signal
It is shown by Scaler master control processing (showing signal processing circuit) driving display screen；There is another identical equipment access
When；Protocol chip, which first can carry out linking up with the equipment being followed by, understands its power input, fan-out capability, to determine which system set by
Available electricity, and other equipment charge is given, the USB2.0 accessed afterwards can be assigned to " down going port " and (be similar to keyboard, mouse, U
Disk) interface, it can solve the compatibling problem of power supply and USB2.0 equipment in this way.At this time, have plant-grid connection (or first connect power supply,
Access device afterwards) when；If the equipment being inserted into below is only power-supply device, protocol chip can be linked up first with the equipment being followed by
Understand its power supply fan-out capability, and requests suitable power supply to the equipment charge first accessed and give us display device power supply.
Switch chip is to support to show the anti-problem of signal sequence in the positive anti-plug of USB-C.It is assisted in positive anti-plug
View chip can detect, and notify Switch chip.
USB port switch is that the equipment that protocol chip is used to control access is connected with USB-HUB " uplink port "
Or with " downlink port " connection, the equipment of access is that power supply then connects " downlink port ", and the equipment of access is (computer, hand
Machine, plate), then what is first accessed is " uplink port ".
It is the explanation of the working principles of our double USB-C display Driver Cards, control logic and the order of connection above.
Embodiment is solely for for chip pin schematic diagram of the Fig. 2 into Figure 14 and circuit structure diagram, to its circuit
In capacitance, resistance value be not construed as limiting, and the analogous circuit of other structures can be also used in the technical program, also cope with it
It is protected.
Two TYPE-C interfaces on display Driver Card all have signal reception, data transmission and PD power management
Function, one TYPE-C interface can be used for power input when in use, another TYPE-C interface for data pass
It is defeated, it is convenient and efficient；In addition, in use, when only one the connection equipment connection of two TYPE-C interfaces, display is driven
Protocol chip on movable plate card can be connected by communication control circuit with equipment is connect, and from connection equipment power-extracting, take electricity failure
Then display screen does not work；It takes electricity success then to light display screen, and USB HUB chip is connected by connection USB port switch,
And multiple USB interfaces for data connection are extended by USB HUB chip.
When accessing two connection equipment:
1. power unit: the equipment power-extracting that system can be strong from power supply fan-out capability, and the equipment charge weak to capacity of power；
The coupling part 2.USB2.0: if the equipment first accessed has been " upper port ", the equipment accessed afterwards is lower end
Mouthful, the equipment such as first accessed does not use " upper port ", then the equipment connection " upper port " accessed afterwards.
3. showing signal section: the case where according to equipment, keeping it from changes, (equipment is exported, then receives display；It does not export,
It does not show).
The present invention detects different connection equipment by TYPE-C interface so that TV, mobile phone or plate it is aobvious
Display screen can be provided when needing power supply by connecting equipment, and preferentially select the stronger connection equipment of power supply capacity,
And charge for weaker equipment, using effect of the invention is improved, is brought great convenience to the use of people.
