Problems solved by technology

[0010] When the panel parameters are set to the wrong panel model, the display effect will be unsatisfactory, or even unable to display
In addition, when multiple sets of panels of different models are set at the same time or at different times, it is necessary to prepare multiple sets of different panel parameters in advance, and manually set the panel parameters that meet the panel model one by one during the production process, so it is inconvenient to manage
[0011] To sum up, the existing technology has the disadvantages of labor and time-consuming, error-prone, inconvenient management, high cost, etc.

Embodiment Construction

[0033] Please refer to figure 2 , which is a block diagram of an embodiment of the present invention applied to a control chip of a display device and other related circuits. The circuit board (PCB) 200 includes a non-volatile memory 260 and a control chip 250 . The non-volatile memory 260 can store panel parameters of different types of panels supported by the control chip 250, and each panel parameter includes at least one of the following setting values: panel resolution, total number of horizontal pixels, and total number of vertical pixels , display interval, and display frequency. If the control chip adopts wrong panel parameters, the display condition of the panel will be unsatisfactory or even impossible to display. The control chip 250 includes a control unit 210 , a peripheral control unit 230 , a GPIO terminal 232 , and a display control unit 220 . The control unit 210 can control the peripheral control unit 230 to make the peripheral control unit 230 detect the...

Abstract

The invention relates to a method for setting parameters. The method for setting parameters is applied to a display device which comprises a control chip and a display panel. The method for setting parameters includes the following steps that multiple panel parameters are stored in a non-volatile memory and correspond to different types of panels respectively; a state signal of a preset connection pin is detected and the state signal corresponding the type of the display panel; according to the state signal, a panel parameter is selected among the panel parameters; the control chip generates an output signal according to the panel parameter.

Description

technical field [0001] The present invention relates to a method for setting panel parameters, and in particular to a method for automatically setting panel parameters by utilizing the state signal of a predetermined pin of a control chip. Background technique [0002] Generally speaking, after the design of the control chip of the panel is completed, the control chip can usually be applied to various types of panels. For example, different models of TV panels of the same series can all operate using the same control chip, and each model can represent various types of TV panels. [0003] In order to make different types of panels have the best display effect, different panel parameters (panel parameters), or called video output setting values ​​(video output setting values), need to be configured in the control chip. These panel parameters can be panel resolution, total number of horizontal pixels (H total ), the total number of vertical pixels (V total ), display interva...
