摘要： The present invention discloses a liquid crystal display (LCD) panel and the method for manufacturing the same. A transparent electrode layer serving as a pixel electrode is laid out and simultaneously, a transparent electrode layer is laid out on top of a thin-film transistor (TFT) acting as a shift register. The transparent electrode layer can mask the influence of the common voltage of the common voltage electrode layer on the TFT. Therefore, the shift in the I-V characteristics of the TFT can be prevented due to the common voltage of the common voltage electrode layer. In this way, not only power consumption of the TFT in operation can be reduced to increase the life span of the TFT, but also power chips can be prevented from malfunctioning due to an overabundant flow of electric current which causes display abnormality.

摘要： The present invention discloses a backlight module with a related liquid crystal display (LCD) which activates light emitting diodes (LEDs) by utilizing an alternate control method. The present invention utilizes two inverters to individually activate two sets of LEDs through an alternate method. During the same switching cycle period, the two sets of LEDs take turns turning on/off; that is, the two set of LEDs are in a closed state in a duty cycle of 50 percent. Since each set of the LEDs are in a closed condition in half the time during a switching cycle period, both of excess temperature produced by all of the LEDs when lightened simultaneously and thermal power generated during the lighting of the LEDs can be effectively reduced.

摘要： A liquid crystal display (LCD) device is disclosed. The LCD device comprises a plurality of pixel units arranged in the form of a matrix. Each of the pixel units comprises: a scan line; a data line; a first storage capacitor; a liquid crystal capacitor; and a first TFT, having a source electrically connected to the data line, a gate electrically connected to the scan line, and a drain electrically connected to the first storage capacitor. Each of the pixel units further comprises a second TFT, having a gate, a source electrically connected to the drain of the first TFT, and a drain electrically connected to the liquid crystal capacitor. The gates of the second TFTs are electrically connected with each other to control the second TFTs to be turned on simultaneously so as to tilt the liquid crystal molecules. Because this shortens the time to wait for scanning of the gates is shortened and increases the time duration in which the backlight can emit light, the number of LEDs can be reduced to lower the cost.

摘要： A backlight module detecting abnormal lamp tubes and an LCD employing such a backlight module are proposed. The LCD includes a voltage calculator for detecting voltage applied on ends of a lamp tube to monitor the lamp tube. Once the lamp tube becomes abnormal, the voltage varies accordingly. The voltage calculator calculates a voltage signal from a plurality of lamp tubes and produces a voltage value. A protection circuit regards the voltage value as a feedback signal to decide if there are any abnormalities. Once any of the lamp tubes is abnormal, the protection circuit transmits the voltage signal to a pulse-width modulated integrated circuit (PWM IC) to activate a protective function. The protection circuit of the present invention obtains the protection signal by sampling the voltage signal of the ends of the lamp tube and then gets the control signal by means of the calculation of the voltage calculator. Thus, voltage level retrieved from the protection signal are less easily affected by dimming and temperature.
