Problems solved by technology
However, since the known semi-transmissive display only uses a single TFT to deliver a predetermined driving voltage to simultaneously drive the transmissive sub-pixels and the reflective sub-pixels, it cannot properly address the difference in driving voltage between the transmissive pixel electrode and the reflective pixel electrode. Adjust the working parameters of the driving circuit in a timely manner, so that the optimization of the picture cannot be achieved

Embodiment Construction
[0016] Please refer to figure 1 , figure 1 It is a schematic diagram of a pixel region of the semi-transmissive display of the present invention. Such as figure 1 As shown, the transflective display includes a plurality of pixels 1 arranged at the intersection of multiple columns of scan lines 2 and multiple rows of data lines 3, and each pixel 1 includes a transmissive sub-pixel 11, a reflective sub-pixel 12, and a pixel driving circuit TFT 4 for driving the transmissive sub-pixel 11 and the reflective sub-pixel 12. TFT 4 includes a gate electrode connected to the scan line 2 for receiving a pixel switching / addressing signal, a source electrode connected to the data line 3 for receiving a pixel display signal, and a drain electrode connected to To the transmissive pixel electrode 11 and the reflective pixel electrode 12 of the pixel 1 . Wherein the drain electrode 5 forms a storage capacitor (storage capacitor, Cs) with a common electrode (common electrode) 7 and a dielec...

The invention provides a driving method for half-transmitting monitor; the monitor includes several image elements which are set at the cross point of several data lines and several scanning lines, and each image element includes a transmitting sub-element, a reflection element and a driving circuit for driving the two kind of elements. The driving method is: it carries on a examining program at first, in order to examine the operation mode of the half-transmitting monitor, then adjusts the parameter of the driving circuit according to the result of the examining program, in order to make the operation mode reach a best displaying effect. When the operation mode is a transmitting operation mode, the parameter is used to make the transmitting sub-element to reach the best effect; when the mode is a reflection operation mode, the parameter is used to realize the best effect of the reflection sub-element.
Description
technical field [0001] The present invention relates to a driving method of a display, in particular to a driving method of a transflective display. Background technique [0002] With the vigorous development of today's electronic products, the display device used as one of the human-machine interfaces has stricter quality requirements. Among them, liquid crystal displays have gradually become the mainstream of the market due to their excellent qualities such as non-radiation, light and thin, and low energy consumption, and are widely used in notebook computers (notebooks), personal digital assistants (personal digital assistants, PDAs), Portable electronic information products such as digital cameras and mobile phones. Liquid crystal displays are flat panel displays that emit light passively, so an external light source is needed to provide the light required for screen display. According to the type of external light source, liquid crystal displays can generally be divide...
