Detailed Implementation
[0018] Embodiments of this application will now be described in more detail with reference to the accompanying drawings. While embodiments of this application are shown in the drawings, it should be understood that this application may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided to make this application more thorough and complete, and to fully convey the scope of this application to those skilled in the art.

These terms are only used to distinguish information of the same type from one another. For example, without departing from the scope of this application, first information may also be referred to as second information, and similarly, second information may also be referred to as first information. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.
[0020] Unless otherwise expressly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.
[0021] TCON is a timing control chip, mainly used to drive the row drive signals, column drive signals, data enable signals, pixel clock signals, etc. required by the panel, and to control the data transmission timing and charging time. When the ambient temperature changes, the TCON output voltage and timing do not change with the ambient temperature, resulting in wasted power consumption.
[0022] To address the aforementioned issues, embodiments of this application provide a method, system, electronic device, and storage medium for adjusting TCON power consumption based on temperature. This method can automatically adjust the TCON voltage and timing according to changes in ambient temperature, thereby avoiding power waste.
[0023] The technical solutions of the embodiments of this application are described in detail below with reference to the accompanying drawings.
[0024] Figure 1 This is a schematic flowchart illustrating a method for adjusting TCON power consumption based on temperature, as shown in an embodiment of this application.
[0025] See Figure 1 A method for regulating TCON power consumption based on temperature includes: Step S101: Obtain the real-time temperature value of TCON, and determine whether the real-time temperature value of TCON is greater than the over-temperature protection threshold. If yes, run the forced protection strategy; otherwise, output the temperature range.
[0026] It should be noted that, firstly, the TCON enters the initialization phase upon power-up. After the TCON chip powers on, the VDD voltage stabilizes at 3.3V, and the internal reset circuit completes the reset of all registers, caches, and state machines. The TCON main controller reads the temperature threshold, voltage parameter table, and timing parameter table stored in the EEPROM via the I2C interface and stores them in the internal RAM cache. Then, it outputs control signals to the DC-DC converter, configures the default voltages Vcore=1.0V and Vio=3.3V, writes the default timing to the timing register, sets the pixel clock to 180MHz, and sets the timing redundancy to 20%. Finally, it outputs the normal display timing to the display panel, completing the panel lighting and normal display initialization.
[0027] Furthermore, the temperature detection module inside the TCON collects the real-time temperature value of the TCON and determines whether the real-time temperature value exceeds the over-temperature protection threshold. The over-temperature protection threshold here is 90℃. When the real-time temperature value of the TCON exceeds the over-temperature protection threshold, a forced protection strategy will be executed.
[0028] The forced protection strategy is as follows: immediately shut down unnecessary drive channels, respond to the forced voltage adjustment command, forcibly write timing parameters, and output an alarm level signal. In other words, the TCON chip immediately shuts down unnecessary drive channels, sends a forced voltage adjustment command to the DC-DC converter of the voltage adjustment module, configuring the TCON core voltage Vcore to 0.7V and the I / O port voltage Vio to 1.8V; simultaneously, it writes forced timing parameters to the register of the timing adjustment module, specifically a pixel clock of 90MHz and a timing redundancy of 5%; it synchronously sets the alarm GPIO pin, outputs an alarm level signal, and adjusts the temperature sampling period to 50ms.
[0029] Furthermore, if the real-time temperature value of TCON is less than the over-temperature protection threshold, the next step of precise identification will be performed.
[0030] Step S102: Identify the real-time temperature value and temperature range of TCON, and output an adaptive adjustment strategy.
[0031] It should be noted that several temperature ranges are set, and each temperature range has a corresponding adaptive adjustment strategy. A suitable adjustment strategy is obtained by matching the real-time temperature value of TCON with the temperature range.
[0032] Figure 2 for Figure 1 A more detailed implementation method, a temperature-based TCON power consumption regulation method, includes: Step S201: Collect temperature data at a preset period, calculate the temperature data, and output an analog voltage; after amplifying the analog voltage, perform analog-to-digital conversion on the analog voltage and output the TCON real-time temperature value; determine whether the TCON real-time temperature value is greater than the over-temperature protection threshold. If yes, run the forced protection strategy; if no, output the temperature range, which includes a low temperature range, a medium temperature range, and a high temperature range.
[0033] It should be noted that the preset period can be 100ms or 50ms. When the real-time temperature value of TCON exceeds the over-temperature protection threshold, the preset period is 50ms; otherwise, it is 100ms. Furthermore, the TCON's internal timer triggers temperature sampling with a period of 100ms. The built-in NTC thermistor acquires the TCON die temperature and outputs an analog voltage. This voltage is amplified by an operational amplifier and sent to a 12-bit ADC module. The ADC performs analog-to-digital conversion, converting the analog signal into a 12-bit digital temperature value, which is then sent to the TCON main control register. TCON reads this register to obtain the current temperature value T and then performs digital filtering. The final effective temperature Te is obtained by averaging the five consecutive temperature measurements (after removing the maximum and minimum values) and storing it in the temperature comparison register.
[0034] Step S202: If the real-time temperature value of TCON is in the low temperature range, the low temperature range adjustment strategy is triggered as an adaptive adjustment strategy; if the real-time temperature value of TCON is in the medium temperature range, the medium temperature range adjustment strategy is triggered as an adaptive adjustment strategy; if the real-time temperature value of TCON is in the high temperature range, the high temperature range adjustment strategy is triggered as an adaptive adjustment strategy.
[0035] It should be noted that the low-temperature range is Te≤40℃, the medium-temperature range is 40℃<Te≤60℃, and the high-temperature range is Te>60℃. If the real-time temperature value of TCON is within the low-temperature range, the low-temperature range adjustment strategy is triggered. TCON outputs an I2C control signal to the DC-DC converter, configuring the low-temperature range voltage Vcore=1.0V and Vio=3.3V. Simultaneously, low-temperature timing parameters are written to the timing register, with a pixel clock of 180MHz and a timing redundancy of 20%, completing the low-temperature range parameter configuration. If the real-time temperature value of TCON is within the medium-temperature range, the medium-temperature range adjustment strategy is triggered. TCON outputs an I2C control signal to the DC-DC converter, configuring the medium-temperature range voltage Vcore=0.9V and Vio=3.0V. Simultaneously, medium-temperature timing parameters are written to the timing register, with a pixel clock of 150MHz and a timing redundancy of 15%, completing the medium-temperature range parameter configuration. If the real-time temperature value of TCON is within the high-temperature range, TCON outputs an I2C control signal to DC-DC to configure the high-temperature range voltage, Vcore=0.8V, Vio=2.7V, and simultaneously writes high-temperature timing parameters to the timing register, with a pixel clock of 120MHz and timing redundancy of 10%, thus completing the high-temperature range parameter configuration.
[0036] It should also be noted that TCON updates timing and voltage according to the adaptive adjustment strategy.
