Problems solved by technology

[0009] However, the conventional low-temperature polysilicon process display 100 directly forms the circuits of the gate driver 120 and the switch group 130 on the substrate, and uses an external source driver 150 to operate in a 3-PAAT driving manner, so that the switch group operates At a relatively high operating frequency, it will affect the process yield of the display panel

Embodiment 1

[0052] Please refer to image 3 , which shows the front view of the mobile information device according to Embodiment 1 of the present invention. The mobile information device 290 in this embodiment at least includes a casing 270 , a display and an operation interface 280 . The mobile information device 290 is, for example, a digital still camera (Digital Still Camera, DSC), a digital video camera (Digital Video Camera, DVC), a mobile phone, and a digital personal assistant. The casing 270 of the mobile information device has an opening for exposing the display area 211 of the display. The operation interface 280 is disposed on the casing 270 and is used for controlling the display and related settings relative to the ASIC 250 .

Embodiment 2

[0063] The difference between this embodiment and the above-mentioned embodiments lies only in the installation position of the application-specific integrated circuit, and the rest of the components are the same, and the reference numerals are still used, and will not be repeated here. Figure 5 A block diagram of the display of the mobile information device according to the second embodiment is shown. The display 400 of this embodiment at least includes a substrate 410 , a flexible circuit board 440 and an ASIC 450 . The substrate 410 has a display area 211 , and several scan lines 212 parallel to each other and several data lines 213 substantially perpendicular to these scan lines 212 and parallel to each other are formed in the display area 211 alternately. The ASIC 450 is disposed along the extending direction of the scan line 212 . by Figure 5 For example, the application-specific integrated circuit 450 is located on the right side of the display area 211 and disposed...

Embodiment 3

[0067] The difference between this embodiment and the above-mentioned first embodiment lies in the manufacturing process of the display in the mobile information device, which further affects the installation positions of the gate driver and the switch group.

[0068] The display of the mobile information device of this embodiment adopts Low Temperature Poly-Silicon (LTPS) process, the pixel array and part of the driving circuit are formed on the substrate at the same time, and the circuit of the thin film transistor (TFT) can be miniaturized. In addition, the application-specific integrated circuit is integrated on the substrate, and the 24-PAAT driving method is used to reduce the operating frequency of the switch group and improve the process yield.

[0069] Please refer to Figure 6, which shows a block diagram of a display in a mobile information device according to Embodiment 3 of the present invention. The display 300 of this embodiment includes a substrate 310 , an AS...

Abstract

The invention relates to a mobile information device and a display with narrow frames thereof; wherein, the display comprises a substrate, a number group of pixel and a specifically applied integrated circuit. The substrate is provided with a display region. The number group of pixel is intertwined into a whole by a plurality of parallel scanning lines and a plurality of parallel information lines, and is arranged in the display region. The integrated circuit specifically applied is positioned in the extending direction of the scanning lines, and the integrated circuit comprises a gate driverand a source driver. The configuration manner of the internal components in the invention can effectively save space and further reduce the size of the mobile information device by reducing frames.
