Description of the Invention: [Technical Field] [0001] The present invention relates to a driving voltage, and more particularly to a driving circuit for a display panel that saves circuit area. [Prior Art] [〇〇〇2] Press, today's technology is booming, information products are innovating, and 满足 meets the different needs of the public. Most of the early displays were cathode ray tube (CRT) displays, which were extremely large in size and power consumption, and the radiation generated was a 'hazard to the body for users who used the display for a long time. As a result, today's displays on the market are gradually replacing the old CRT displays with liquid crystal displays (LCDs). Liquid crystal displays have the advantages of being thin and light, low in radiation and low in power consumption, and thus have become the mainstream in the current market. Furthermore, with the rapid leap forward in panel production technology in recent years, the production cost of touch panels has been greatly reduced. Therefore, touch panels have been widely used in general consumer electronic products, such as mobile phone handsets. Small electronic devices such as digital cameras, digital music players (Mp3), personal digital assistants (PDAs), and satellite navigation devices (GPS). On these electronic products, the touch panel is configured on the display screen of the electric appliance to allow Users can perform interactive input operations, greatly improve the user-friendliness of the communication interface between people and machines, and improve the efficiency of input operations. 100123749 In order to solve a wide range of power supply specifications in the application of a single power supply for mobile phones, For example, 2. 3V~4. 6V, and reducing the area of the driving chip of the driving display panel, and simultaneously proposing the driving modes of the two kinds of demand form number A0101, page 3 / total 25 one hundred 1002040239-0 201222521.

If the storage capacitor is disposed in the driving circuit 1', The area of the drive circuit 1' is increased. Therefore, how to solve the above problem is to provide a novel driving circuit for saving the circuit area of the display panel, which can reduce the area occupied by the storage capacitor externally connected to the driving circuit, and even eliminate the need for an external storage capacitor, so that the above problem can be solved.

The storage inductor 704 is coupled to the control transistor 7 〇〇 and the diode 7 〇 2 to store the energy of the input voltage vIN, and One end of the output capacitor 7〇6 is coupled to the storage inductor 704. The other end of the output capacitor 706 is connected to the ground to store the energy of the input voltage vIN, and generates a supply voltage for output to the driving units 50, 52. In summary, the driving circuit of the display panel for saving circuit area of the present invention is generated by converting a single pixel data by a complex digital analog conversion circuit to generate a pixel signal, and the plurality of driving units are respectively coupled to the digital analog conversion circuits. 'to amplify the pixel signal, generate a driving signal, and transmit the driving signal to the display panel to display a picture, and a plurality of booster shirts are connected to the driving units, and according to a control supply-supply voltage To the multiple (four) cells of the material panel, to reduce the external storage capacitor area, and even do not need external storage capacitors, to achieve the purpose of saving circuit area. The delay and the available users of the industry shall comply with the special requirements and requirements of the Patent Law of the People's Republic of China. In the case of Geng, the invention shall be filed in accordance with the law, and the patent shall be granted at an early date. The 100123749 signal generates a supply voltage and supplies the supply voltage to the drive units separately. Thus, the present invention is provided by the above-mentioned boosting materials, respectively, and the form number is Α0101, page 10/total 25 pages 201222521, but the above is only a preferred embodiment of the present invention, and is not used The scope of the present invention is defined by the scope of the invention, and the equivalents and modifications of the shapes, structures, features and spirits of the present invention are intended to be included in the scope of the present invention.
