Problems solved by technology

[0007] usually, figure 1 The switching element of the pixel unit shown is a transistor, for example, a thin film transistor, a field effect transistor, etc. Since the transistor has a gate, a source, and a drain, it is affected by process factors such as design rules, critical dimensions (CD) and layout. These transistors occupy necessary layout area, thus limiting the miniaturization and high integration of display devices

Embodiment Construction

[0026] The display array of the display device according to the embodiment of the present invention uses Micro Electro Mechanical Systems (MEMS, Micro Electro Mechanical systems) switches instead of transistors as switching elements, and the MEMS switches can be merged together to form a switch array.

[0027] MEMS technology is a cutting-edge technology in the 21st century based on micro / nanotechnology, which refers to the technology for designing, processing, manufacturing, measuring and controlling micro / nano materials. MEMS technology uses the combination of microelectronics technology and micromachining technology to integrate mechanical components, optical systems, drive components, and electronic control systems into a micro-system as a whole unit. MEMS switch is an application of MEMS technology, which is an ultra-miniature mechanical switch made by semiconductor silicon processing technology.

Abstract

The invention discloses a switch array and a display array of a display device. The display array of the display device comprises a switch array and a pixel array, wherein the switch array comprises M*N MEMS (micro-electromechanical systems) switches, M is a line number, and N is a row number; the MEMS switches in each line are respectively controlled by corresponding line driving signals, and each MEMS switch respectively outputs a corresponding row data signal under the control of a corresponding line driving signal; and the pixel array comprises M*N pixel units which are respectively and correspondingly coupled with the M*N MEMS switches, and each pixel unit displays according to the row data signal output by the corresponding MEMS switch. The switch array and the display array of the display device can reduce layout area and realizes high integration.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a switch array and a display array of a display device. Background technique [0002] In micro-projection display technology, such as transmissive liquid crystal display (LCD), reflective digital light processor (DLP), reflective liquid crystal on silicon (LCOS), etc., or in flat panel display technology, such as liquid crystal display, organic light-emitting display (OLED), electrophoretic display, plasma display (PDP), etc., the pixel unit (or electro-optical modulation unit) of the display array is strobed row by row or interlaced by the row drive signal, and displayed according to the column data signal. [0003] figure 1 A circuit diagram of a display array of an existing liquid crystal display device is shown, the display array includes MxN pixel units (M, N are natural numbers), wherein M is the number of rows, N is the number of columns, figure 1 Only 2 rows x 2 column...
