Abstract: The present invention provides a LED package assembly and a backlight module. The LED package assembly provides three adjacent individual LED package structures separated from each other, for generating red light, green light and blue light, respectively, all of which are mixed with each other to form white light. The foregoing design can ensure that each color light can not be absorbed or scattered by other color fluorescent powders, so that it is advantageous to individually control each color, enhance the luminous efficiency of each color light and expand the color gamut of white light.

Abstract: 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.

Abstract: 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.
