Embodiment Construction

[0031] In order to illustrate the present invention more clearly, the present invention will be further described below in conjunction with preferred embodiments and accompanying drawings. Similar parts in the figures are denoted by the same reference numerals. Those skilled in the art should understand that the content specifically described below is illustrative rather than restrictive, and should not limit the protection scope of the present invention.

[0032] For different application software, the control board can output different frequencies according to the application requirements to achieve the optimal display effect of the application software. When a normal product receives different frequencies, the IC will call different modes according to different frequencies. Group parameters realize frequency switching, but limited by the current serious leakage of LTPS, LTPS-based products will have obvious flicker screens at low frequencies, which cannot meet user needs. ...

Abstract

The embodiment of the invention discloses a display module based on low-temperature polycrystalline silicon, a display device and a display method. The display module comprises a display panel, a control mainboard and a frequency generator, wherein the control mainboard is used for starting application software according to operation of a user, detecting first display frequency of the application software and transmitting the first display frequency to the frequency generator so as to output second display frequency used for display of the display panel, and the second display frequency is greater than or equal to a frequency threshold value of the display panel. By arranging the frequency generator, the display frequency of the display panel can be larger than or equal to the minimum frequency at which splash screen does not occur on the display panel, so that the problems existing in the prior art are solved, the problem that splash screen occurs in an existing LTPS-based display device at low frequency can be solved, the display effect of the display module is improved, and wide application prospects are realized.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a low-temperature polysilicon-based display module, display device and display method. Background technique [0002] Low temperature polysilicon (LTPS for short) is a branch of polysilicon technology. For display devices, the use of polysilicon liquid crystal materials has many advantages, such as thin film transistor circuits can be made thinner, smaller, and lower power consumption. The electron mobility of the LTPS thin film transistor display device can reach more than 200cm2 / V-sec, which can effectively reduce the area of ​​the thin film transistor, thereby increasing the aperture ratio, and can reduce the overall power consumption while enhancing the brightness of the display device. In addition, the higher electron mobility can integrate part of the driving circuit on the glass substrate, reducing the number of driving ICs, and can also greatly improve the reliability of...
