Field of the Invention The present invention relates to a control circuit, a control method therefor, and a display device therefor, and more particularly to a gamma control circuit, a control method thereof, and a display device therefor. [Prior Art] Since consumer electronics are on display! I has more enhanced data processing capabilities, more saturated colors and higher performance requirements, making the cathode ray tube (CRT), which once dominated the market, apparently giving way to liquid crystal displays, plasma displays and projections. Many new displays, such as monitors, show that the modern display (4) technology can accurately represent the brightness and color changes of the physical world. Among them, common image adjustment parameters are: color temperature, gamma value, contrast , grayscale value, brightness, tilt angle, chroma... and more. For example, for a factory-displayed display, the gamut space formed by the three primary colors should have been standardized, that is, the color of the three primary colors in the display, the seat 'has been recognized' and simultaneously The white point chromaticity coordinate value corresponding to the three primary colors is also within the characteristic chromaticity coordinate range. In addition, the third important parameter is the control of the car Z, and the eye is controlling the gamma value. The method is mainly based on =! know: Γ _ circuit block: its == complex control unit 14 and complex signal line 18, and in this implementation = (four) early element 12 and gamma (four) unit 14 system = = t = Several drive units 10 are based on different design two == mA drive unit 14 different components to carry the substrate", 13 Ϊ: Γ 蝴 控制 control unit 彳 4 series _ several external operation amplification "TM 16 and number of turns The electrical connection resistor (4) in series is connected to an independent driving unit 1〇, wherein in the control circuit of 5 200849207, it must be _ complex oblique stalking amplifier 16 = self- 驱 驱 鲜 fresh 1 The screaming Jia Wei pressure value fresh phase factor = so 'flow county f 141 141 depends on the gorge Wei value door ^ and its ί ==., gang - ride shaft axle method [invention content] The main purpose of this U is to propose a kind of display device for the gamma, ^ application, which is not used The additional external hanging type == square = the area of the substrate carrying the substrate, and at the same time achieving the effect of reducing the cost L; to, for the purpose of the above, the present invention first provides the ς driving unit system and control The single-connected gamma control unit is connected and blocked, and the resistors are arranged in the final wheel of the serial drive unit to generate corresponding gamma adjustment signals for adjustment, and the circuit and the display group are electrically connected. The connected driver, ",", display module, and backlight module are driven by the driver module to generate a plurality of numbers, and the second one's one-month silk group provides a light source, and the number of wires is _ backlight enemy and test, so that the light source can be 200849207 Under the pre-set conditions, the person enters the display group and displays the image. The shooting and conversion module has at least the control unit, the complex drive unit and the galaxy control element. Each of the drive elements includes a plurality of operational amplifiers, and The control unit has a complex number : The connected resistor 'and the per-resistance _ corresponding to the singular operational amplifier with = gamma voltage. Therefore, the display device using the gamma control circuit not only has a smaller component arrangement to reduce the size of the carrier substrate in the display device, but the circuit space design of the overall display device can be more flexible. The number of components used by the coffee maker to control the power is reduced, thereby reducing the burden on the overall cost. The effect of the invention, the technical content, the characteristics and the effects achieved by the invention are further exemplified by the concrete _ ___ plus _, #. [Embodiment] In order to enable the touch device to maintain the good gamma voltage value of Victoria County, and at the same time to show the component cost of the device, the present invention proposes a display of the gamma control circuit and its control method and application. In the following, the main technical features and the spirit of the invention are combined with the actual sample collection. Please refer to Figure 2 for the implementation of the gamma control circuit disclosed in the present invention. The gamma control circuit includes a plurality of control units, a moving unit 20, and a gamma control unit 24, wherein the control unit 22 drives the 単兀20 and the gamma control unit 24 by a complex signal. The line 28 is used as a medium for transmitting messages and includes a plurality of resistors 241 in the gamma control unit 24, and the resistors 241 are electrically connected in series, and at the same time, because the drive is originally set in the drive For example, in the repair circuit, the material signal is amplified to facilitate the long-distance repair line. The correct data signal can still be displayed. Therefore, each resistor 241 Department of death The corresponding signal line 28 is electrically connected to any two of the operational amplifiers 26 disposed in the driving unit 2Q. The gamma control unit 24 in this embodiment is known from the structure of the gamma-controlled woven road disclosed by the second bicycle. The unit and the control unit 22 are integrated in the same component. The moving unit 2G is disposed on the other independent component carrying substrates 21, 23. Therefore, when the control unit 2: carries the gamma value for calculation, it simultaneously borrows From 'early 7^20 required and corresponding to each-resistance 241 drive" 9 working system early 24% of the resistance 241 electric 1 outside the squatting early 20 inside the tube to the female crying χ A driving unit 20 calculates a corresponding voltage value °, and is connected between the driving unit 20 and the gamma control unit 24, and transmits the signal to the shaft unit 2Q through the connecting signal. The value can be reached - set. In order to make the peaches move as early as 20, and then on the actual configuration structure of the control circuit of Gamma, please continue to refer to Figure 3, which is the current version Schematic diagram of the block, similarly, in this gamma control electricity 24 = Ϊ 二 system early ^ 22, a plurality of drive units 2 〇 and a gamma control unit Ί lack of work early ^ 22, drive unit 2 〇 and gamma control The unit 24 is also used as a medium for transmitting messages by the number ^^28, and in the gamma control unit “ "(4) village connection (four) resistance 241 'and these resistors 241 are part of the signal line 28 is electrically connected to the operator % in the corresponding driving unit 2, but in order to shorten the configuration length of the signal line 28 to reduce the area of the component carrying substrate 21, 23, %' in this embodiment Based on the resistance in the Gamma control unit 24, such as the control unit between the operator 26 in the driving material 2G, as a basis for the control of the Gamma control unit (10), according to the statement, As shown in the graph of Fig. 3, since each drive unit 2 corresponds to the electricity in the Gamma_particle 24 241. Therefore, for one of the driving units 2〇1, one of the resistors 241 corresponding thereto and the driving unit 2〇1 are disposed on the same component, and the component board disposed on the control unit 22 is disposed. 25, so, the spacing between the _ 201 and the gamma control unit 24 is shortened, so that the signal line 28 connected between the driving unit 兀 = 〇 1 and the gamma control unit 24 is also corresponding. The shortening of the ground can not only reduce the complexity of the wiring of the positive body, reduce the use of the material, but also reduce the overall product of the 200849207, and at the same time, the signal line can be controlled by the shorter signal line 28 to reduce the signal in the driving unit 2. The problem is caused by the transfer between the control, therefore, the control system is more energy-saving and more energy-efficient. Overall, for the common liquid crystal display device, the above-mentioned drive unit material drive unit (source driver) And the sweeping unit (gate dnVer). In addition, according to the above two kinds of real sample wipes provided by the gamma control circuit structure 2: ! = unit in the unit, that is to control this - drive unit At least π: an operational amplifier Therefore, for the wood structure 5, in addition to the circuit structure disclosed in the above two embodiments, the electrical connection electrically connected to the gamma control unit only specifies the driving unit in which it is located. That is to say, in this issue = and ^ transport ~, more _ ground, when - resistance and its electric crane unit, for this operation _ say, (10) can be located in _^== control or 疋 not located In the control of the fresh element, it is located in other drive units. However, regardless of the circuit structure shown in Figure 2 or Figure 3 above, the control method can be continued in Figure 4 The method of the disclosed method is not described below. In the following, the reference to FIG. 2 and the fourth embodiment of the method is shown in step S1, which is to receive an input signal; and in the step, the root is calculated to calculate the complex number. Corresponding to the Gamma control view to meet the _ district ^ ϋ, ^ its Pei County - Jia _ _ so that the control of Gamma in the early several μ of the different resistance 241 can pass through the 2 的 咖 咖 咖 咖 咖 咖Corresponding value, and this is used to adjust the gamma voltage value of the early το 20, and finally, in step S4, Gamma ^ ^ can be based on the received gamma voltage value, to update the display crack element 20 200849207 into the "Wen Ren Xun Lin can be used as a material - the input of the human β as the second itself through the operation Lose the signal and pass it. All of the above signals of σ σ' are transmitted via the signal line 28, and a display device using the gamma circuit is also provided, and the group is connected to the 农 农 植, a backlight module and the electrical connection.
