Description of the Invention: [Technical Field] The present invention relates to a display panel driving device and a driving method thereof, and particularly to a display panel driving device using a single gamma curve and Drive method. [Prior Art] In order to improve the display quality, the display technology enables the human eye to correctly sense the color gradation of each primary color. Usually, the gamma curve is used to map the color gradation of each primary color to the driving voltage required by the display device. . The figure depicts a graph of the gamma curve of each of the primary colors of the organic light-emitting diode. The horizontal axis is the color gradation and the vertical axis is the voltage. The red gamma curve 101 and the blue gamma curve 102 almost overlap, and are represented by a curve in the figure, and the green light curve 103 is different from the curve 101 and the curve 1〇2.显^: Figure 2 depicts an electrical diagram of a conventional organic light-emitting diode display. The organic light emitting diode display comprises a source _ ddVer) 2 organic light emitting diode panel 22, with (10) (phase. source drive brain 21 receiving data to ^^ device (= light group gamma voltage, these three groups of gamma mA voltage eight, "1 three primary color gamma curve sampling value. Source drive; T light, blue gamma voltage will input three data in the data, three sets of drive light, green three sets of drive voltage, the three sets of drive voltage; excellent The color gradation is converted to the panel 22, respectively, and the signal control gate driver oscillating to the organic light-emitting diode board 22 is sequentially scanned. Since three sets of gamma-coded electricity are required, the surface noise of the luminescent diode is greatly improved, and product development is extended. When ^, this circuit is repeated in a few years of product research 5 200809714 V 19216twf.doc / g in the process of goods also - 〇 ^ Mao risk. Figure 3 depicts another - custom road block diagram. Organic light 1 organic light two The electric organic light-emitting diode panel 3 of the polar body display 300 includes the source driver 3, and the data is input to the source driver 33. The external device (not a gamma curve-3) Gamma & source driver 31 according to the color scale of light Switching to the drive ^璧 will input the red, green, and blue 32. The gate driver 33 is input to the organic light-emitting diode panel 32 to perform sequential sweeping. Sex-signal control and organic light-emitting The polar body driver 31 directly refers to FIG. 1 and FIG. 3I according to the same, and since the source gamma curve is a red light gamma, the color light (4), for example, may generate a voltage excessively large, and check the Wang Bai screen. When the green light is green, the gamma curve is 1〇3, and the surface will be greenish. However, if the gamma curve is used, the voltage will be obviously insufficient. King: The picture is 'for red and blue light'. The I surface will still be greenish. The object of the present invention is to provide a panel-saving device that can save cost and reduce circuit complexity, and can be verified. 〃 X reduction ^ development time, and another object of facilitating testing of the present invention is Providing a reduction in circuit complexity and cost, and:: the board driving method, there may be color deviation. h, 1, 1 incorrect color, not mouth mouth, Mao Ming proposed a display panel drive unit and source driver. :, 匕3 夕 姆照表No. 'Multiple comparison table unit according to a monochrome letter gamma curve and a plurality of primary color gamma 200809714 w / ν / ^ νιι W 19216twf. doc / g curve between the color gradation control relationship, the multiple primary colors should be single - A plurality of gamma curves are converted into Zhao (4), Ba-Bai white to μ ^ -- ..., color center value. The source driver is electrically connected to the evening table to receive a plurality of control color scale values. And converting the plurality of control color gradation values into a plurality of driving powers 6 to input the pressure to the display panel according to the single gamma code 2, the μ- is used to electrically drive the plurality of driving lights in an embodiment of the present invention. In the middle, the er, the er, The table unit is configured to receive a plurality of contrast gradation values, and the perturbation mechanism is performed by the number of traversing parameters, and the plurality of pairs of gradation values are converted to == more than one straight, and the plurality of two=source drivers are based on a single > ij] v Tff π relationship, the gradation of the plurality of gradation combination lines is used to input a plurality of combined driving voltages to the display panel. :··动=曲:乂 The above multiple comparison table cells will have multiple ^ drive voltages. Moreover, each of the color gradations having the same drive = on the singular-gamma curve corresponds to the display panel driving of the above-mentioned display panel. The panel driving method, the main steps, clearly propose a kind of display. According to a cover and a private ^ • hundred first, receiving a plurality of primary color letter relationship, a plurality of: color gamma curve between the gradation pairs of the plurality of contrast gradation values: corresponding to the single-gamma curve voltage The relationship is to compare the plurality of driving voltages of the gamma curve of the gamma curve of the plurality of contrast gradations, and input a driving voltage of 200809714 19216 twf.doc/g to a display panel. μ The present invention adopts a structure in which a plurality of _ tables are combined with a perturbation mechanism and a gradation is used to convert a gradation to a corresponding voltage, unlike the conventional technology=the gamma gamma voltage of the annihilation group, thereby saving cost and reducing circuit complexity, ^ Less development time and easy testing and verification. Moreover, in this case, the gradation of the primary color gamma curve is converted to the correct driving power] ',,: = display incorrect color' does not have color deviation. If the invention is a light-emitting diode display panel, the source of the organic light-emitting diode display panel can be directly replaced by a thin-film transistor liquid crystal display panel. Reducing the complexity and cost of the circuit can be of great help. The above-mentioned and other objects, features and advantages of the present invention will become more apparent from the following detailed description of the present invention. The driving method, only the gamma curve to convert the color gradation to the corresponding driving voltage. Single-gamma == lies in the driving voltage range covering multiple primary color signals 'f color W (such as red light (four), blue light signal, green light signal), due to the various color light positive mechanism, the exclusive primary color gamma (4) The ::yuan::: line correctly presents all primary color gradations'. The present invention utilizes the contrast gradation of the dynamic voltage of the show area. Due to the choice of a single gamma curve, the available color gradations of some primary colors are greatly reduced. For this problem, 8 200809714 ^ 19216twf.doc/g can use the perturbation mechanism to display the quality of the original available color gradation. Thus, the source driver can output a corresponding gamma circuit block diagram by expressing the driving voltage corresponding to the single-gamma curve by increasing the voltage.
