[0029] 3. Existing Practices and Their Defects
[0031] However, with the maturity of display products, on the one hand, clients require more and more resolution formats to be supported; The signal parameter processing method can no longer meet the matching design of the existing LCD screen, and a method of dynamically adjusting the signal parameter processing is needed to solve this problem

Embodiment 1

[0057]Example 1, matching the Chimei MT200LW02 LCD screen, the LCD screen specification point frequency range is 97Mhz to 152Mhz, the range of row direction signal points is 1930 to 2300, the effective output signal points of the row direction are 1600, and the effective output signal points of the field direction are 900. The default setting Set the number of output line direction signal points to 1930. When the input signal is 576P (720*57650hz), the output point frequency is 1930*31250*900 / 576=94.23Mhz, which is lower than the lower limit of LCD screen point frequency 97Mhz; after adding the dynamic parameter adjustment module, it is judged that the output point frequency is lower than After the lower limit of the LCD dot frequency, the fixed output dot frequency is the lower limit of the LCD dot frequency of 97Mhz. The inverse algorithm calculates the output signal points in the row direction as 97000000 / 31250 / 900*576=1986 within the range of the LCD screen row direction si...

Embodiment 2

[0058] Example 2, matching the AUO B156XW02 LCD screen, the frequency range of LCD screen specifications is 65Mhz to 85Mhz, the range of signal points in the row direction is 1396 to 2047, the effective signal points in the output row direction are 1366, and the effective signal points in the output field direction are 768. The default Set the number of output line direction signal points to 1396. When the input signal is 800*60072hz, the output point frequency is 1396*48077*768 / 600=85.9Mhz, which is higher than the upper limit of the LCD screen point frequency of 85Mhz; after adding the dynamic parameter adjustment module, it is determined that the output point frequency is higher than the LCD screen point frequency After the frequency upper limit, the fixed output point frequency is 85Mhz, the lower limit of the LCD point frequency. The inverse algorithm calculates the effective number of points in the field direction of the input screen as 48077*1396*768 / 85000000=606. The n...

Abstract

The invention relates to a method for dynamically setting a display equipment output parameter. The method is characterized by: after calculating an output spot frequency, adding a dynamic parameter adjusting module before setting a register output parameter; determining a scope of the output spot frequency; adjusting appropriately a signal parameter so as to accord with a specification requirement of a liquid crystal screen. Through determining the output spot frequency and dynamically calculating and adjusting a display parameter, a matching attribute of liquid crystal screen design and developing can be increased. And simultaneously, a standardized signal parameter detection module provides a high efficient design mode. Possible of the poor signal parameter design caused by mistakes of a designer can be avoided.

Description

technical field [0001] The invention relates to a method for dynamically setting output parameters of a display device. Background technique [0002] 1. VESA standard [0003] All display devices must follow the video display standards developed by the Video Electronics Standards Association, such as figure 1 As shown, the important display parameters of its specification are as follows: [0004] Number of signal points in the row direction (Htotal): the total number of effective signal points in the row direction, the number of blank area points and the number of line synchronization signal points [0005] The number of signal points in the field direction (Vtotal): the total number of effective signal points in the field direction, the number of blank area points and the number of field synchronization signal points [0006] Effective signal points in the row direction (Hdisplay): the number of points in the row direction that actually contains the display data [0007...
