Description
Technical field
The utility model relates to a kind of liquid crystal display, especially a kind of one liquid crystal display.
Background technology
Common display is all comprised of liquid crystal module (be commonly called as liquid crystal display wherein comprises liquid-crystalline glasses and sequential control circuit is TCON the electric circuit constitute, SCALER decoding deck, power panel and constant current source plate) in the market.Can need so production and processing and assembling repeatedly, be all that very billow takes and be loaded down with trivial details on material, logistics, personnel, Production and quality control.Owing to being comprised of polylith PCB circuit board, wiring is complicated, and poor anti jamming capability has so also limited the contour structures of machine, and attractive in appearance thereby profile is difficult to design, the thickness of machine is also difficult to accomplish ultra-thin.
Utility model content
For overcoming above-mentioned the deficiencies in the prior art, the utility model provides one liquid crystal display.
The technical scheme that realizes the utility model object is: one liquid crystal display, comprise liquid crystal display, liquid crystal display backlight circuit, liquid crystal display drive circuit and Power Management Unit, it is characterized in that: Power Management Unit is connected with described liquid crystal display, liquid crystal display backlight circuit, liquid crystal display drive circuit respectively, liquid crystal display is all connected in described liquid crystal display drive circuit with liquid crystal back light circuit, and described liquid crystal display backlight circuit, liquid crystal display drive circuit and Power Management Unit is integrated on a pcb board.
As prioritization scheme of the present utility model, liquid crystal display drive circuit comprises:
TCON unit, for sequential control;
Gamma unit, for generation of gray scale voltage;
With SCALER unit, for generation of LVDS signal, export and input signal is detected.
As prioritization scheme of the present utility model, one liquid crystal display thickness is less than 9mm.
As prioritization scheme of the present utility model, one liquid crystal display provides two kinds of input ports, is respectively VGA interface and DVI interface.
The utlity model has positive effect: TCON circuit, SCALER circuit, backlight circuit, gamma circuit, all combine, with a power management, allow and do not need the power-off of work, can reduce power consumption, by a pcb board, complete all functions, enhance productivity greatly, for store keeping, quality control and production technology, all obtained huge leap, and saved cost.Solve between original PCB feature board and need, by a lot of connector communications, for the test of EMI, to disturb large problem.Because display screen can arbitrarily be changed different models, so there is the aesthetics of very strong versatility and outward appearance.Without designing corresponding casing because of inner structure problem, the thickness below 9mm, is almost the thickness of liquid crystal display entirely, more slim, more portable.
Accompanying drawing explanation
For content of the present utility model is more easily expressly understood, according to specific embodiment also by reference to the accompanying drawings, the utility model is described in further detail below:
Fig. 1 is structural drawing of the present utility model;
Fig. 2 is the structural drawing of liquid crystal display drive circuit;
Fig. 3 is the structural drawing of Power Management Unit 3;
Wherein: 1, liquid crystal display, 2, liquid crystal display drive circuit, 3, Power Management Unit, 4, liquid crystal display backlight circuit, 21, TCON unit, 22, constant current source unit, 23, SCALER unit.
Embodiment
If Fig. 1 is the structural drawing of the utility model one liquid crystal display, this liquid crystal display comprises liquid crystal display 1, liquid crystal display backlight circuit 4, liquid crystal display drive circuit 2 and Power Management Unit 3, liquid crystal display 1 is all connected in liquid crystal display drive circuit 2 with liquid crystal back light circuit 3, as shown in Figure 2, for the structural representation of liquid crystal display drive circuit 2 comprises: TCON unit 21, for sequential control; Gamma correction unit 22, for generation of gray scale voltage; With SCALER unit 23, for generation of LVDS signal, be Low Voltage Differential Signal output and input signal is detected, this liquid crystal display drive circuit 2 is used an IC chip just can realize these functions, before having overcome, need different IC to realize, or even different PCB versions realizes, because connector too much easily produces and disturbs, the problem all having a great impact for the test of EMI, use liquid crystal display drive circuit 2 not only to avoid interference, and saved space and cost.Liquid crystal mesogens display has two kinds of input port VGA interfaces and DVI interface, signal is from DVI interface and the input of VGA interface, enter SCALER unit 23 and carry out data channel selection, picture catching processing, image scaling, the processing such as matrixing become the output of LVDS signal, and SCALER unit 23 also carries out level control and DVI and the VGA signal input detection etc. of key-press input detection and LED light.Then LVDS signal enters TCON unit 21 and carries out color management, brilliance control, jitter elimination etc., and source drive, gate driver circuit task driven control signal can also be exported and in order to realize the control signal of different display modes in TCON unit 21.
Be the structural representation of Power Management Unit 3 as shown in Figure 3, Power Management Unit 4 is for providing voltage to liquid crystal display 1, liquid crystal display backlight circuit 3 and liquid crystal display drive circuit 2.External input voltage is 12V, and the constant current of leading up to drives as liquid crystal display backlight circuit 4 provides supply voltage, and the BUCK DC/DC circuit of separately leading up to is that buck circuit is depressured to 5V.5V has three purposes:
1, through two LDO, be that low pressure difference linear voltage regulator is reduced to respectively 3.3V and 1.8V provides voltage to SCALER unit 23;
2, by LDO, reduce to 3.3V to TCON unit 21;
3, through a BOOST DC/DC circuit, be that boost circuit boosts to 11.24V, 11.24V has 4 purposes:
1) offer liquid crystal display drive circuit;
2) by charge pump circuit be charge pump become 32V (Vgh) and-6.2V (Vgl), Vgl, Vgh are liquid crystal display switching voltage.When being Vgl, liquid crystal display is closed; When being Vgh, liquid crystal display is opened;
3) by dividing potential drop, control 64 GTGs;
4) give repair line chip power supply, be used for repairing liquid crystal display.Use Power Management Unit 4 can adjust separately and control in the sequential of work.Allow and do not need the power-off of work, can reduce power consumption like this, reduce costs.
Liquid crystal display 1 can be changed.At present a lot of displays all cannot general all casings on the market, after each casing external form changes, all need correcting again to match with casing.Owing to being that a pcb board completes all functions now, as long as be exactly a liquid crystal display together with fixing on liquid crystal display nation, for casings all on present market, be all can be general, without need the circuit of multiple corresponding casing because of inner structure problem, so be very strong in the adaptability of casing structure.
One liquid crystal display thickness is less than 9mm.Being exactly the thickness of liquid crystal display 1 like this, is the thinnest on the market machine, and external form can be done very attractive in appearancely.Traditional machine is all that side is thin, and the position on electric discharge road, center is thick, and whole external form is not attractive in appearance.
Above-described specific embodiment; the purpose of this utility model, technical scheme and beneficial effect are further described; institute is understood that; the foregoing is only specific embodiment of the utility model; be not limited to the utility model; all within spirit of the present utility model and principle, any modification of making, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
