Description
Technical field
The utility model relates to a kind of display correction device based on the LVDS interface.
Background technology
Some portable products, as medical B ultrasonic machine, because the restriction of volume, mainboard and display control unit are structure as a whole, it utilizes the LVDS signal of directly output to go control display screen to show that such controlling schemes does not all show calibration function usually, and display effect is relatively poor relatively, but the demonstration of medical B ultrasonic machine needs the correction of gamma and colour temperature to guarantee image effect again, for therapeutic process provides basis for estimation.Therefore, design a kind of display correction device, the LVDS interface is realized the correction of gamma and colour temperature by it, guarantees display effect, just becomes problem to be solved in the utility model.
Summary of the invention
The purpose of this utility model is to adopt a kind of display correction device based on the LVDS interface of programmable logic device (PLD) design, and to realize the gamma and the color temperature correction process of LVDS interface signal, the control display screen display effect guarantees display quality.
The utility model is achieved through the following technical solutions:
A kind of display correction device based on the LVDS interface comprises LVDS receiving element, RAM data storage cell, look-up table stores unit and gamma and color temperature correction unit, and the output signal of gamma and color temperature correction unit is connected with external TTL/CMOS interface display screen.
The LVDS receiving element is responsible for the reception of LVDS signal, and the LVDS form shows signal that receives is converted to the TTL signal.
TTL signal data information after the RAM data storage cell storage LVDS conversion.
The data look-up table of usefulness is proofreaied and correct in look-up table stores unit editor, storage.
Gamma and color temperature correction unit adopt frame per second control algolithm or time-sharing procedure to realize more GTG or color range level, and according to suitable GTG or the color range of look-up table output, finish the GTG or colored demonstration of TTL/CMOS interface display screen.
A kind of display correction device based on the LVDS interface, also comprise the LVDS transmitting element, the LVDS transmitting element is connected between gamma and color temperature correction unit and the external LVDS interface liquid crystal display, and the LVDS transmitting element is packaged as the LVDS signal again with the TTL signal and sends to LVDS interface liquid crystal display.
Described gamma and color temperature correction unit are the synchronous correction of gamma and colour temperature.
Display correction device based on the LVDS interface described in the utility model, the employing programmable logic device (PLD) designs, and has realized the LVDS interface signal is carried out the trimming process of gamma and colour temperature, has guaranteed display quality, improve display effect, satisfied the demonstration needs of instruments such as portable type b ultrasonic machine.Its one-piece construction is simple, practical, and the hardware design to simplify has as far as possible realized the most concise and to the point function, and volume is little, easy to use, and being specially adapted to some images demonstrations needs in the demonstration control procedure of gamma and color temperature correction.
Description of drawings
Fig. 1 is a structured flowchart of the present utility model.
Embodiment
Be further described below in conjunction with 1 pair of the utility model of accompanying drawing:
Display correction device based on the LVDS interface described in the utility model adopts the programmable logic device (PLD) design to realize.Concrete structure comprises LVDS receiving element 1, RAM data storage cell 2, look-up table stores unit 4, gamma and color temperature correction unit 3 and LVDS transmitting element 5.Wherein, LVDS transmitting element 5 is used for being connected with external LVDS interface liquid crystal display 6, to guarantee the normal demonstration of LVDS interface liquid crystal display 6.LVDS transmitting element 5 is connected between gamma and color temperature correction unit 3 and the external LVDS interface liquid crystal display 6.
LVDS receiving element 1: be responsible for the reception of LVDS signal, the LVDS form shows signal that receives is converted to the TTL signal.
RAM data storage cell 2: the TTL signal data information after the storage LVDS conversion, call in order to follow-up gamma and color temperature correction unit 3.
Look-up table stores unit 4: be used to edit, store the data look-up table of proofreading and correct usefulness, proofread and correct shows signal according to look-up table.
Gamma and color temperature correction unit 3: adopt the frame per second control algolithm to realize more color range level, and export suitable color range according to look-up table in the mode of gamma and colour temperature synchronous correction, the assurance procedure for displaying in order, accurately, reliably carry out.
LVDS transmitting element 5:LVDS transmitting element 5 is a signal conversion unit, and LVDS transmitting element 5 sends on the LVDS interface liquid crystal display 6 after being responsible for the TTL signal is packaged as the LVDS signal again, finishes the normal procedure for displaying on the LVDS interface liquid crystal display 6.
Certainly, in the said structure,, then do not need LVDS transmitting element 5 to carry out conversion of signals if display screen is the interface display screen of TTL/CMOS, output signal after gamma and 3 processing of color temperature correction unit directly is connected with external TTL/CMOS interface display screen, finishes the normal demonstration of signal and gets final product.Gamma and color temperature correction unit 3 equally also can adopt the spatial jitter method to realize more color range or GTG level, and according to suitable color range or the GTG of look-up table output, and then finish colour or GTG demonstration.
In the use, at first will calculate good data look-up table and write look-up table stores unit 4, determine that gamma and colour temperature are synchronous correction; Then, utilize LVDS receiving element 1 to receive the shows signal of LVDS form, and store in the RAM data storage cell 2 after being converted into the TTL signal; At last, gamma and color temperature correction unit 3 adopt the frame per second control algolithm to realize more color range level, and according to the suitable color range of look-up table output of storing in the look-up table stores unit 4, after LVDS transmitting element 5 is repackaged into the LVDS signal with the TTL signal, send on the LVDS interface liquid crystal display 6, realized clear, the reliable demonstration on LVDS interface liquid crystal display 6 after gamma and the colour temperature synchronous correction, remedied and originally do not proofreaied and correct not fogging clear, the inaccurate drawback that procedure for displaying may bring, improved display quality.
