Abstract
Description
本發明係關於一種驅動系統、顯示裝置及其驅動方法。The present invention relates to a drive system, a display device, and a method of driving the same.
液晶顯示裝置係利用液晶分子會因應電場變化而轉動的特性，來控制光線的穿透量，進而使液晶顯示裝置產生豐富的影像。雖然液晶顯示裝置已慢慢成熟，但是仍存在許多問題待解決，其中之一為饋穿(feed through)效應。所謂的饋穿效應是因為顯示面板中的薄膜電晶體與掃描線之間具有寄生電容，當脈波式的掃描訊號在開關薄膜電晶體時，會使得存在於液晶電容中的電荷藉由寄生電容釋出，因而造成顯示錯誤的灰階。The liquid crystal display device controls the amount of light penetration by utilizing the characteristics that the liquid crystal molecules rotate in response to changes in the electric field, thereby causing the liquid crystal display device to generate a rich image. Although liquid crystal display devices have matured slowly, there are still many problems to be solved, one of which is a feed through effect. The so-called feedthrough effect is due to the parasitic capacitance between the thin film transistor and the scan line in the display panel. When the pulse wave type scan signal is used to switch the thin film transistor, the charge existing in the liquid crystal capacitor is caused by the parasitic capacitance. Released, thus causing grayscales that display errors.
為解決饋穿效應的情形，在液晶顯示面板的驅動架構中設計有一切角電路，請參照圖1A所示，切角電路依據一原始驅動訊號VGHP而輸出一切角驅動訊號VGH，使得放電速度能延緩，以降低饋穿效應及線失真(Line distortion)。請參照圖1B所示，其為習知的一種切角產生電路1之一示意圖，其包含一第一切換元件11、一第二切換元件12及一第三切換元件13。其中，第一切換元件11及第二切換元件12係分別依據時序控制單元(圖未示出)所輸出之第一切換控制訊號GVOFF 及第二切換控制訊號GVON 進行切換，而操作於導通或截止狀態。當第一切換元件11操作於導通狀態時，第二切換元件12係為截止狀態。此時，切角產生電路1將輸出掃描線訊號之直流成分。反之，當第一切換元件11操作於截止狀態，第二切換元件12係為導通狀態。此時第二切換元件12將提供切角產生電路1一放電路徑，另外由於第一切換元件11為截止狀態導致第三切換元件13操作於截止狀態，驅動訊號因開路而無法輸出，藉此可以產生切角驅動訊號VGH。In order to solve the feed-through effect, all corner circuits are designed in the driving structure of the liquid crystal display panel. Referring to FIG. 1A, the chamfering circuit outputs all angular driving signals VGH according to an original driving signal VGHP, so that the discharge speed can be Delay to reduce feedthrough effects and line distortion. Please refer to FIG. 1B , which is a schematic diagram of a conventional chamfering generating circuit 1 , which includes a first switching component 11 , a second switching component 12 and a third switching component 13 . The first switching element 11 and the second switching element 12 are respectively switched according to the first switching control signal GV OFF and the second switching control signal GV ON outputted by the timing control unit (not shown), and are operated to be turned on. Or cutoff status. When the first switching element 11 is operated in the on state, the second switching element 12 is in an off state. At this time, the chamfering generating circuit 1 outputs the DC component of the scanning line signal. On the contrary, when the first switching element 11 is operated in the off state, the second switching element 12 is in an on state. At this time, the second switching element 12 will provide a discharge path of the chamfering generating circuit 1. In addition, since the third switching element 13 is in the off state due to the first switching element 11 being in the off state, the driving signal cannot be output due to the open circuit, thereby A chamfer drive signal VGH is generated.
承上所述，放電電路中的放電電阻R1 必須承載切角產生電路所有的電流，而放電電阻R1 的溫度會因為負載端有許多的電荷而逐漸上升，若提高更新頻率，而放電電阻R1 無法增加散熱速度時，則會導致熱問題的加乘效應，因此在現階段必須仰賴多顆大尺寸電阻並聯在放電電阻R1 的路徑上，底下則有大面積的散熱墊，使得熱能平均分散開來，而不致使電阻燒毀，然而此方式會因為這些電阻排列緊密，仍使該區域的溫度偏高。As described above, the discharge resistor R 1 in the discharge circuit must carry all the current of the chamfering generating circuit, and the temperature of the discharging resistor R 1 gradually rises due to a large amount of electric charge at the load end, and if the update frequency is increased, the discharge resistor is increased. When R 1 cannot increase the heat dissipation rate, it will cause the additive effect of the thermal problem. Therefore, at this stage, it is necessary to rely on a plurality of large-sized resistors in parallel on the path of the discharge resistor R 1 , and at the bottom there is a large-area heat-dissipating pad to enable thermal energy. It is evenly dispersed without causing the resistor to burn out. However, this way, because these resistors are closely arranged, the temperature in the region is still high.
