Description of the Invention: [Technical Field] The present invention relates to a special application integrated circuit and an application method thereof, and particularly to an apparatus and method for suppressing startup noise suppression of a flat freshman. [Prior Art] Since the optoelectronics industry is actively investing in R&D and adopting large-scale production equipment, the quality of liquid crystal display (LCD) continues to increase. Beckham continues to decline, making the application field of liquid crystal displays rapidly expanding. In terms of computer applications, LCD monitors not only make the display screen of notebook computers progress from the early small-size general image quality to the current medium-sized high-definition quality, but also step into a larger-sized monitor field, ready to replace the display. The cold cathode tube TV market. People's livelihood applications, such as car navigation systems and LCD TVs, have become more viable due to the low cost and high quality of liquid crystal displays. The liquid crystal display material, the front signal receiving end of the circuit structure is a liquid crystal display control circuit, including an analog digital converter (ADC), a digital image input decoding receiver (DVI), a scale control circuit (Scaler), a screen adjustment circuit. (〇sd), microprocessor (MCU), etc.; the middle section of the circuit has a timing controller (T_c〇N), DC boost converter iDCfC.C〇nVerter) (Gamma Voltage Generator), etc. The liquid crystal display drives the integrated circuit: including the gate drive integrated circuit (gated_IC) and the source drive integrated circuit (Zhuo Lili. I Tian night _ not for the moment when the drive circuit is started at the start, if there is instability When the material or the miscellaneous Hit condition occurs, it will affect the normal input driving signal of the liquid crystal display. At this time, the surface will immediately display an abnormal picture. In general, the cause of the startup redness can be divided into two parts. _, is the gate circuit is not set to off, or the open __ gate circuit is unstable, resulting in the noise caused by the residual charge of the source 200818076 circuit, which affects the startup screen; the second is After a short period of time after power-on, the gate circuit is turned on to make the external data wheel out to the liquid crystal display, but at this time, the external input data signal has not reached a steady state, resulting in an abnormal output signal, showing an abnormal picture. US Patent No. US5257105 discloses a noise The device and method for processing must pre-determine the position where the noise appears on the screen as a basis for inserting black data, increasing the complexity of the circuit components, and additionally using a synchronous signal as feedback control, so that the system cannot be simplified. The purpose of the present invention is to provide a special application integrated circuit and an application method thereof, which utilizes a black picture generating unit to generate a full black picture data, so that the display displays a full picture, effectively Block any noise from causing poor display on the flat panel display when starting up, solve the noise caused by the residual charge of the source circuit, and avoid abnormal images when starting up.

Furthermore, in step S13, an image data is rotated. When the processing unit % receives the image of the whole love and there is no: the furnace, the black image is rotated to the data transmission unit 55, and finally transmitted to the signal transmission interface driver. II and display the all-black image on the flat panel display; in addition, if the processing unit 54 is connected to the (4) data job, the data signal is transmitted to the display device to display the image screen. According to the above, when the present invention detects that the input voltage Vi is greater than the startup voltage V(10), and the data of the external antenna is not =, the processing unit S4 transmits the all-black image to the data unit 55. Black screen; when the input voltage Vi is greater than the startup voltage Vact' and the stable data ship tiger is detected, the processing unit it 54 transmits the external data degradation level by (4) the transmission unit 55 to the display age data crane The picture. The trunnion of the present invention is used as a timing diagram such as the third @ and fourth®, special application chip=SIC) integrated with the daily sample controller in the wafer, and the input of the special application chip: L is 'the voltage at which the normal operation can be started. For Vact, when Vm is greater than vact, the source integrated circuit start pulse (source IC startpulse, 8 200818076 STH), source integrated circuit latch pulse (s〇urce IC iatchpulse, Lp), The gate IC clock (CLKV) and the gate IC 〇utput enable (OE) signal are scanned. First, the source integrated circuit start-up clock (STH) signal appears first, the source integrated circuit (sourceIC) starts to receive the data signal; when the data enable (DE) is south (HIGH), the special application chip judges the read Whether the data is valid data, the source packet path stores the received data in the scratchpad; when the source integrated circuit latch pulse (Lp) acts, the source integrated circuit (source 1C) converts the data into an analog voltage signal output. To drive the liquid crystal panel, when the gate clock (CPV) is high (high), a horizontal line of the panel is turned on and the analog data output by the source integrated circuit is read, and the gate clock (cpv) is lower than w). Stop reading the analog voltage. When the scan integrated circuit output enable (〇E) is high (_), it will force the gate integrated circuit to open (gateICGff) to avoid interference between the two horizontal display lines. , according to an embodiment of the invention, a timing diagram when a special application chip does not detect an external turn-in signal, when the initial input voltage Vin (3 3v) rises above (90/〇Vin) 4 and Special application 曰曰曰# does not side to the stable external wheeled data, at this time, the application chip internally generates black screen data (blaekdata), _ its data = energy (1) E) signal and other control signals transmitted by the dragon transmission unit The black surface data is stored in the circuit and stored in the temporary storage n, and then the source integrated body lock pulse (Lp) i pole Japanese pulse, (cpv), scan integrated output start ((10) and other control ship y crystal panel A black screen is displayed. The liquid crystal t diagram is a timing diagram for describing a special application chip when the input signal is input according to an embodiment of the present invention, when the initial input voltage % rises higher than the mouth application application chip is turned to three external parts.
