Embodiment Construction

[0013] The I2C (Inter-Integrated Circuit, inter-integrated circuit) bus has the characteristics of less signal lines and easy operation. In many fields, the I2C bus has been more and more widely used. The I2C bus is a serial bus composed of a data line SDA (Serial Data, serial data) and a clock line SCL (Serial Clock, serial clock), which can send and receive data, between the CPU and the controlled IC, between the IC and the IC Two-way transmission between ICs, the maximum transmission rate can reach 100kbps. There are three types of signals transmitted by the I2C bus:

[0014] Start signal: When SCL is high level, SDA jumps from high level to low level, indicating the start of data transmission;

[0015] End signal: When SCL is low level, SDA jumps from low level to high level, indicating the end of data transmission;

[0016] Response signal: After receiving the 8bit data, the IC that receives the data sends a specific low-level pulse to the IC that sends the data, indic...

Abstract

The invention provides a temperature reading method for a plasma display and a device; the method comprises the following steps: detect the temperature of the plasma display and change the control waveform of a low-voltage control module of the plasma display according to the temperature, so as to lead the waveform generated by a high-voltage driving circuit module of the plasma display for driving the voltage to be changed along with the change of the temperature; the invention realizes to improve the technical effect of plasma display effect and the stability.

Description

technical field [0001] The invention relates to the field of displays, in particular to a control method and device for a plasma display. Background technique [0002] In a conventional plasma display, the control waveform generated by the low-voltage control module is usually used to control the on-off of the MOS tube in the high-voltage drive circuit module, so that the high-voltage drive circuit module can generate a driving voltage for driving the plasma display screen for normal display. [0003] During the implementation of the present invention, the inventor found that the control waveform generated by the low-voltage control module in the related art remains unchanged, so that the waveform of the driving voltage generated by the control waveform control also remains unchanged. However, when the temperature of the plasma display changes, if the waveform of the driving voltage remains unchanged, the display effect and stability of the plasma display will be affected. ...
