Embodiment
As shown in Figure 1, it is the flow chart of steps of the electrostatic protection method of a preferred embodiment of the present invention display unit, and described display unit comprises host computer system and demonstration module, and described method comprises the steps:
Step S101, described host computer system generates the first check code by data message through preset algorithm.
In the present embodiment, host computer system be processor integrated the cell phone mainboard of MIPI-DSI function, show the demonstration module of module for matching with cell phone mainboard power, operating voltage etc.Transfer of data between cell phone mainboard and demonstration module is followed MIPI-DSI communications protocol, and MIPI-DSI is that MIPI alliance proposes the serial line interface of a kind of high speed, low-power consumption for mobile device, can meet high-resolution and show, reduces the requirement of display module power consumption.Cell phone mainboard need to be according to CRC(cyclic redundancy check (CRC) when showing that module sends data message) or ECC (error checking and correction) algorithm generate the first check code.Step S102, described host computer system is encapsulated as Packet Generation to described demonstration module by described data message and described the first check code.
Be that aforesaid the first check code and corresponding data information send to demonstration module in the lump.The effect of check code is, when data message produces mistake in transmitting procedure, data message receiving terminal can show that the data message of reception is whether identical with the data message sending by the first check code, even can check out the position of misdata in the data message of reception and correct according to the first check code.
As: in MIPI-DSI communication protocol, host computer system sends the data messages such as Pixel Information or control command to showing module in the mode of serial, and follows specific communication mode in the process of transmission, comprises data packet format and error correcting and detecting mechanism.Information transmits and adopts data packet format, comprises long data bag and short packages.
In the present embodiment, the first check code can be ECC code.Host computer system is added respectively start bit and check code in the front and back of data message, is packaged into together packet, and take packet and send to demonstration module as unit.
Step S103, described demonstration module receives and resolves described packet and obtains described data message and described the first check code.
As: show the packet that module Receiving Host system sends and follow the parsing of MIPI-DSI communications protocol to obtain data message and ECC code, and the data message in a plurality of packets is combined and reverted to original data information sequence.
Step S104, described demonstration module generates the second check code according to described preset algorithm and the described data message receiving.
As: show that module is according to and host computer system generates the algorithm that CRC that the first check code uses or ECC etc. are identical and the data message receiving calculates the second check code.
Step S105, more described the first check code of described demonstration module and described the second check code, when different, produce error flag information from described the second check code at described the first check code.
Described error flag information exchange conventional " 0 " or " 1 " represents, be stored in the drive circuit register that shows module, different with the actual data message sending for the data message that represents to receive, follow-uply can take countermeasure according to this error flag position, as data message is retransmitted, or carry out error correction etc.
Step S106, described host computer system detects and responds described error flag information, sends initialization information to described demonstration module.
Step S107, described demonstration module carries out initialization according to described initialization information.
Described initialization information is the setup code that described host computer system sends to described demonstration module, described demonstration module completes the parameter configuration such as voltage of register in drive IC according to setup code, the brightness, contrast, colour vividness of described demonstration module displays etc. are set, then wait for signals such as receiving data message that described host computer system sends and control command.Because applicant is in long-term mobile phone electrostatic test process, find that static causes showing when module is abnormal, wherein this static can make described packet information change on certain probability, and then produce corresponding error flag information, for this reason, said method is found to show abnormal method and approach to showing that module carries out initialization, increasing, is made to show that the display performance of module is higher when producing above-mentioned error flag information.
As shown in Figure 2, it is the functional block diagram of the display unit 20 of a preferred embodiment of the present invention, comprise: host computer system 201 and demonstration module 203, in the present embodiment, host computer system be processor integrated the cell phone mainboard of MIPI-DSI function, show the demonstration module of module for matching with cell phone mainboard power, operating voltage etc.Described host computer system 201 comprises: verification unit 211, encapsulation unit 212 and control unit 213.Show that module 203 comprises: resolution unit 231, authentication unit 232, indexing unit 233 and initialization unit 234.
Indexing unit 233 is for more described the first check code and described the second check code, at described the first check code, when different, produces error flag information from described the second check code.
Described error flag information exchange conventional " 0 " or " 1 " represents, be stored in the drive circuit register that shows module, different with the actual data message sending for the data message that represents to receive, follow-uply can take countermeasure according to this error flag position, as data message is retransmitted, or carry out error correction etc.
For this reason, above-mentioned display unit 20 is found to show abnormal method and approach to showing that module 203 carries out initialization, increasing, is made the display performance of display unit 20 higher when producing above-mentioned error flag information.
The above embodiment has only expressed several execution mode of the present invention, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the scope of the claims of the present invention.It should be pointed out that for the person of ordinary skill of the art, without departing from the inventive concept of the premise, can also make some distortion and improvement, these all belong to protection scope of the present invention.Therefore, the protection range of patent of the present invention should be as the criterion with claims.
