Description of the new type: [Technical field to which the new type belongs] This creation is an improvement of the structure of the converter transformer, especially a kind of output capable of stabilizing the induced voltage, so as to improve the stability and reliability of its luminous efficiency. More uniform backlight. [Previous technology] Press, the general LCD panel uses a discharge iamp such as a cold cathode fluorescent lamp (CCFL) as the backlight of the panel (back ligh0), this capture lamp is passed through the inverter (Inverter) circuit to drive, and in order to meet the requirements of high voltage output, usually use a converter transformer to drive; as shown in the first figure, it is a schematic diagram of the general converter transformer, which is mainly a winding frame (Bobbin) 1, the first iron core 12 and the second iron core 13, and the winding frame (B0bbin) l is provided with a plurality of separation grooves u on the side edges, and is formed into a primary side winding area 1 Π and The secondary winding area 112 is used to wind the primary winding 14 and the secondary winding 15 respectively to further connect the power source and the load. However, due to the increasing size of the LCD panel, the length and number of lamps used have also increased. The driving voltage is also increased accordingly. Therefore, in general applications, the principle of the voltage division of the interval U between the separation grooves is used, and the number of the separation grooves Π is set in accordance with the south of the use of the packing pressure to make the product reliable. Improved; The load use state (see Figure 2), which passes through the cold cathode tube (CCFL) 2 is a characteristic load with negative temperature equivalent impedance, plus its temperature rises and its impedance decreases after conduction, making it based on cost For consideration, a secondary winding 15 is often used to correspond to two cold cathode tubes (ccFl) 2 in parallel. M269553 'However, because the two cold cathode tubes (CCFL) 2 have different impedances, it is easy for cold cathode tubes (CCFL) 2 The shunt effect at the tube end causes the current of the cold cathode tube (CCFL) 2 to be uneven, resulting in a large difference in brightness; (see Figure 3) To overcome the above situation of the cold cathode tube (ccfl) 2 current unevenness, -General industries are all through the addition-matching balance coil 3 :: basin cold cathode tube (CCFL) 2_ Qian Xiang should be fine to get "balanced money" and the brightness has also been effectively improved. However, considering the cost, a matching balance is added. The coil 3 not only relatively increases its cost, but also causes the space usage of the circuit board to be limited. Therefore, it is not a good design in practice. Therefore, after considering the characteristics of the discharge lamp, the stability of the backlight light source is uniform. hair The characteristics of the converter transformer have been greatly improved, and this kind of converter transformer structural improvement has been successfully developed.
