  • Publication number: 20140160065
    Abstract: A time slot scanning method that enables the capacitive touch screen to implement multiple scanning modes, where the said capacitive touch screen comprises the capacitance matrix and data processing modules that are electrically connected thereto; the said scanning method refers to a data acquisition mode where the signal scanning is initiated in a cycle and the received data generated due to scanning are acquired. The present invention enables the touch screen to execute multiple scanning modes with the time slot scanning method. Under the circumstances where the master scanning mode is executed, the scanning course of the slave scanning mode will be inserted in sections into the scanning course of the master scanning mode.

  • Publication number: 20120062510
    Abstract: A capacitance touch screen with mesh electrodes includes a first electrode group and a second electrode group made of transparent conductive material. Particularly, at least either the first electrode or the second electrode includes at least two sub-electrode plates, all the sub-electrode plates in the electrodes which are the same are arranged in accordance with a mesh structure. The capacitance distribution of the prior art is changed from concentrated capacitance to decentralized distributed capacitance through the mesh electrodes, to ensure the touch screen to have higher effective capacitivity even in suspended state, the waterproof performance of the touch screen is increased, and the properties including ESD resistance, aging resistance, etc. of the capacitance touch screen are enhanced.

  • Publication number: 20110221700
    Abstract: A mutual capacitance touch screen with electrodes arranged on dual conductive material films, which comprises an upper electrode film and a lower electrode film, and the two electrode films respectively comprise an electrode plane made of transparent conductive materials and an insulated plane made of transparent insulating materials. The insulated planes of the two electrode films are fused together. Lower electrode plates are arranged on the electrode plane of the lower electrode film separately, and shielding electrode plates are arranged in the clearance between the lower electrode plates. Therefore, the lower electrode plates and the shielding electrode plates are distributed to the whole electrode plane of the lower electrode film. The touch screen of the present invention can isolate interference from the display screen in the conditions that the thickness is not increased and the shielding electrode film is not required to be arranged individually.
