摘要： Embodiments of the present invention set forth methods and systems for driving display devices. In one embodiment, a first set of image data to be displayed on a display panel is stored. During a first time period, a reset signal is asserted to set the display panel associated with a common panel voltage to a predictable state. Subsequent to the first time period, a control signal is asserted to load the first set of image data for a first subframe within a frame on the display panel, wherein this first set of image data is further adjusted by a first adjustable reference voltage. A designated light for the display panel is turned on to display the first set of image data in parallel with the storing of a second set of image data for a subframe within the frame to be displayed.

摘要： The invention relates to an LED current driving system. The LED current driving system comprises an LED driver. The LED driver comprises at least one LED driving unit for outputting a driving current to an LED. Each LED driving unit comprises a plurality of current sources and a plurality of switches. The switches are connected to the corresponding current source. Each switch controls the ON/OFF state of the corresponding current source in accordance with the duty cycle control signal and a current control signal. Therefore, by integrating the LED driver on the LCOS panel, the LED current driving system of the invention can decrease the pin number of the LCOS chip, the overall area and the system cost so as to improve the yield of the LED current driving system. Besides, the LED current driving system utilizes the current sources to form the driving current to stably and precisely control the driving current flowing through the corresponding LED so that the color quality of the image can be improved.
