Description
Technical field
The present invention relates to field of display, especially a kind of one liquid crystal display.
Background technology
Display common in the market is all made up of liquid crystal module (be commonly called as that liquid crystal display wherein comprises that liquid-crystalline glasses and sequential control circuit and TCON circuit form, SCALER decoding deck, power panel and constant current source plate).Production and processing repeatedly and assembling can be needed like this, material, logistics, personnel, Production and quality control are all very billow expense and loaded down with trivial details.Owing to being made up of polylith PCB, wiring is complicated, and poor anti jamming capability, also limit the contour structures of machine like this, thus profile be difficult to design attractive in appearance, the thickness of machine is also difficult to accomplish ultra-thin.
Summary of the invention
The technical scheme realizing the object of the invention is: one liquid crystal display, comprise liquid crystal display, liquid crystal display backlight circuit and liquid crystal display drive circuit, liquid crystal display is all connected in liquid crystal display drive circuit with liquid crystal back light circuit.
As prioritization scheme of the present invention, liquid crystal display also comprises Power Management Unit, for providing voltage to liquid crystal display, liquid crystal display backlight circuit and liquid crystal display drive circuit.
As prioritization scheme of the present invention, liquid crystal display drive circuit comprises:
TCON unit, for sequential control;
Gamma unit, for generation of gray scale voltage;
With SCALER unit, export for generation of LVDS signal and input signal is detected.
As prioritization scheme of the present invention, one liquid crystal display thickness is less than 9mm.
As prioritization scheme of the present invention, one liquid crystal display provides two kinds of input ports, is USB interface and DVI interface respectively.
The present invention has positive effect: TCON circuit, SCALER circuit, backlight circuit, gamma circuitry, all combine, with a power management, allow and do not need the power-off of work, power consumption can be reduced, all functions are completed by one piece of pcb board, enhance productivity greatly, huge leap is all achieved for store keeping, quality control and production technology, and saved cost.Solve between original PCB feature board and need by a lot of connector communication, large problem is disturbed in the test for EMI.Because display screen can arbitrarily change different models, so have the aesthetics of very strong versatility and outward appearance.Without the need to designing corresponding casing because of inner structure problem, the thickness of below 9mm is almost the thickness of liquid crystal display entirely, more slim, more portable.
Accompanying drawing explanation
In order to make content of the present invention more easily be clearly understood, below according to specific embodiment also by reference to the accompanying drawings, the present invention is further detailed explanation, wherein
Fig. 1 is structural drawing of the present invention;
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
As the structural drawing that Fig. 1 is the present invention's 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, export for generation of LVDS signal and Low Voltage Differential Signal and input signal is detected, this liquid crystal display drive circuit 2 uses an IC chip just can realize these functions, need different IC to realize before overcoming, or even different PCB versions realizes, because connector too much easily produces interference, the problem that the test for EMI all has a great impact, use liquid crystal display drive circuit 2 to not only avoid interference, and save space and cost.Liquid crystal mesogens display has two kinds of input port USB interface and DVI interface, signal is from DVI interface and USB interface input, enter SCALER unit 23 and carry out data channel selection, picture catching process, image scaling, the process such as matrixing becomes LVDS signal and exports, and SCALER unit 23 also carries out key-press input and detects and the Automatic level control of LED light and DVI and VGA signal input detection etc.Then LVDS signal enters TCON unit 21 and carries out color management, brilliance control, jitter elimination etc., and TCON unit 21 can also export source drive, gate driver circuit task driven control signal and the control signal in order to realize different display modes.
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 constant current of leading up to drives provides supply voltage for liquid crystal display backlight circuit 4, separately leads up to BUCK DC/DC circuit and buck circuit to be depressured to 5V.5V has three purposes:
1, reduce to 3.3V and 1.8V respectively through two LDO and low pressure difference linear voltage regulator and provide voltage to SCALER unit 23;
2,3.3V is reduced to TCON unit 21 by LDO;
3, boost to 11.24V through a BOOST DC/DC circuit and boost circuit, 11.24V has 4 purposes:
1) liquid crystal display drive circuit is supplied to;
2) 32V(Vgh is become by charge pump circuit and charge pump) and-6.2V(Vgl), Vgl, Vgh are liquid crystal display switching voltage.When for Vgl, liquid crystal display is closed; When for Vgh, liquid crystal display is opened;
3) 64 GTGs are controlled by dividing potential drop;
4) to 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 power consumption be reduced like this, reduce costs.
Liquid crystal display 1 can be changed.At present a lot of display all cannot general all casings on the market, and after each casing external form change, all needing again to change plate could match with casing.Owing to being that one piece of pcb board completes all functions now, as long as together with fixing on liquid crystal display nation be exactly a liquid crystal display, can be general for existing commercially all casings, without the need to needing 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 machine the thinnest on the market, and external form can be done very attractive in appearance.Traditional machine is all that side is thin, and the position on electric discharge road, center is thick, and whole external form unsightly.Above-described specific embodiment; object of the present invention, technical scheme and beneficial effect are further described; be understood that; the foregoing is only specific embodiments of the invention; be not limited to the present invention; within the spirit and principles in the present invention all, any amendment made, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
