Embodiment
Embodiment 1
As shown in Figure 1, visual programming liquid crystal display in the present embodiment, comprise MCU, control circuit, driving circuit, LCD MODULE, memory circuit, the data input/output terminal of MCU connects the data input/output terminal of memory circuit, the control signal output ends of MCU connects the signal input end of control circuit, the signal output part of control circuit connects the signal input part of driving circuit, and the signal output part of driving circuit connects LCD MODULE.
Described MCU receives (data processing equipment is sent here) pattern data, and send into memory circuit and preserve, then call the interior pattern data of memory circuit according to receiving the picture and text control signal, and give control circuit with control signal, control circuit is given driving circuit with display data transmissions after receiving control signal, driving circuit changes into the needed voltage of LCD MODULE to the video data that transmits, provide LCD MODULE required voltage accurately, LCD MODULE is according to the variation of liquid crystal voltage, under the effect of extraneous light, produce the B﹠W effect, demonstrate the required content of client.Interim used various patterns and standard Chinese character storehouse (by data processing equipment and MCU communication) pre-deposit in the memory circuit in the display interface.
