Description
Affiliated field
Patent of the present invention relates to measurement and the debugging technique that video shows product, especially is suitable for the photochromic automatic adjusting and testing system's constructive method and the device thereof of plasma (PDP) TV and liquid crystal (LCD) TV one class panel TV.
Background technology
Adopt the television set of liquid crystal (LCD), plasma (PDP) flat panel display device to be referred to as panel TV.As everyone knows, the distinguishing feature of panel TV is thin thickness, in light weight, power consumptive province, flicker free, radiationless; In addition, the rich interface of panel TV, the vision signal that can receive cable TV radio frequency (RF), VCD video (AV), computer (RGB), digital DVI and simulate YPrPb.Because panel TV can satisfy the needs of Digital Television well, it has become the main flow of colour TV development of future generation, will become the strongest competitor of TV market of future generation dominance.
Panel TV is as the digital information display terminal, and its photochromic performance is very important techniques performance index.Panel TV is compared with traditional C RT colour TV, in vividness, the authenticity of color reproduction; Both still there are differences the uniformity of color, contrast, visual angle aspects.Compare with traditional C RT colour TV in view of panel TV and to have many significant advantages, thereby market is growing to the demand of panel TV.International and domestic display industry all is devoted to the exploitation of panel TV, constantly has new product to introduce to the market.In the overall situation of market economy, the competition of like product is very fierce, in the industry even the outer good panel TV business opportunity of enterprise of industry and squeeze body one after another in wherein.
The competition intension of panel TV, except improving the technical performance of product, and constantly study and improve outside the flat panel television display part self character, businessman also very focuses in the panel TV production process its photochromic performance detection and adjustment, make the panel TV product can reach optimum photochromic performance, satisfy the needs of people to Digital Television, simultaneously, the enterprise operator pursues the low cost of the photochromic performance measuring and adjusting system of product and high-effect again.Thereby the method and apparatus that proposition is used for photochromic Performance Detection of panel TV and adjustment is necessary, is again vital.
People are not difficult to find that there is following defective in it from prior art:
(1) present, many enterprises adopt traditional photochromic regulating and measuring system constructive method of TV, transfer the master plate TV, its capital equipment is made up of the color analyzer of two kinds of different models and single colourity probe, the dedicated video signal source that is disposed thereof usually, the equipment of system is separate, it is very complicated to constitute configuration, and effective utilization is difficult to performance.
(2) liquid crystal (LCD) TV that belongs to panel TV together adopts different display devices with plasma (PDP) TV, and its characteristics of luminescence has evident difference.Thus, LCD TV and plasma electrically apparent are produced with link such as test and must be adopted different equipment and technical measures.At present, must adopt different color analysis instruments to measure the colorimetric characteristics of LCD TV and plasma television: chromaticity coordinate and brightness.The main distinction of the color analyzer that adopts is to use different colourity probes.Brightness difference on the LCD TV all directions must adopt the colourity probe that has the optical imagery camera lens, measures the color on certain direction.The PDP TV can think to have identical brightness on all directions, can adopt the color analyzer of measuring common CRT colour TV to measure.
(3) belong to liquid crystal (LCD) TV and plasma (PDP) TV of panel TV together, in the assembling and setting process, to the production line body require identically, thereby LCD TV and plasma television are generally all produced on same production line.Yet, LCD TV must adopt different color analyzers to measure again with plasma television, thereby, on the identical station of production line body altogether, need to place two cover color analyzers, cause the station space crowded and the measuring equipment investment increases and instrument is alternately idle and reduce benefit.
(4) panel TV can receive analog and digital signal.Because the difference of signal processing circuit, the colorimetric characteristics of panel TV can be variant with the variation of input signal kind.In order to guarantee best photochromic display characteristic, under different signals, need to adjust the TV set circuit parameter, to guarantee consistency, vividness and the authenticity of color reproduction.At present, the debugging of the panel TV of market sale provides the detection signals such as photochromic, several picture, sound accompaniment of RF, AV, RGB, DVI, YPrPb equisignal system formula with signal source, be mainly used in the visual relatively photochromic performance of colour TV, this type of professional signal source design requires high, circuit is very complicated, photochromic test and adjustment inconvenience automatically, the price comparison costliness.In fact, use instrument that panel TV is carried out photochromic test and automatic adjustment, only need the controllable grey scale signal of brightness, obviously, use above-mentioned professional signal source, waste greatly construction system cost height.
(5) colourity of panel TV is transferred and is surveyed the technology that main employing contact hand-held or the microphone tripod is manually adjusted the colourity probe, because all size panel TV screen size is big, hand-held contact is manually adjusted the shake easily of colourity probe, it is slow again that the contact of microphone tripod is manually adjusted the speed of colourity probe positions, be difficult to satisfy the colourity accent mass metering of LCD colour TV and PDP colour TV and the efficient requirement that all size screen sizes panel TV is transferred survey, and, increased personnel and the cost of measuring technology.
