The matrix employs a-Si Thin Film Transisto
9、r as the active element. It is a transmissive type display operating in the normally white mode. It has a 23.0 inch diagonally measured active display area with Full HD resolution (1080 vertical by 1920 horizontal pixel array) Each pixel is divided into Red, Green and Blue sub-pixels or dots which a
10、re arranged in vertical stripes. Gray scale or the brightness of the sub-pixel color is determined with a 8-bit gray scale signal for each dot, thus, presenting a palette of more than 16,7M colors with Advanced-FRC(Frame Rate Control). It has been designed to apply the interface method that enables
11、low power, high speed, low EMI. FPD Link or compatible must be used as a LVDS(Low Voltage Differential Signaling) chip. It is intended to support applications where thin thickness, wide viewing angle, low power are critical factors and graphic displays are important. In combination with the vertical
12、 arrangement of the sub-pixels, the LM230WF5-T2F2 characteristics provide an excellent flat panel display for office automation products such as monitors. Color Gamut 72%(Typ.)

PrecautionsPlease pay attention to the followings when you use this TFT LCD module.7-1. Mounting Precautions(1) You must mount a module using holes arranged in four corners or four sides.(2
85、) You should consider the mounting structure so that uneven force (ex. Twisted stress) is not applied to the Module. And the case on which a module is mounted should have sufficient strength so that external force is not transmitted directly to the module.(3) Please attach the surface transparent pr
86、otective plate to the surface in order to protect the polarizer. Transparent protective plate should have sufficient strength in order to the resist external force.(4) You should adopt radiation structure to satisfy the temperature specification.(5) Acetic acid type and chlorine type materials for t
87、he cover case are not desirable because the former generates corrosive gas of attacking the polarizer at high temperature and the latter causes circuit break by electro-chemical reaction.(6) Do not touch, push or rub the exposed polarizers with glass, tweezers or anything harder than HB pencil lead.
88、 And please do not rub with dust clothes with chemical treatment. Do not touch the surface of polarizer for bare hand or greasy cloth. (Some cosmetics are detrimental to the polarizer.)(7) When the surface becomes dusty, please wipe gently with absorbent cotton or other soft materials like chamois s
89、oaks with petroleum benzene. Normal-hexane is recommended for cleaning the adhesives used to attach front / rear polarizers. Do not use acetone, toluene and alcohol because they cause chemical damage to the polarizer.(8) Wipe off saliva or water drops as soon as possible. Their long time contact wit
90、h polarizer causes deformations and color fading.(9) Do not open the case because inside circuits do not have sufficient strength. 7-2. Operating precautions(1) The spike noise causes the mis-operation of circuits. It should be lower than following voltage : V=200mV(Over and under shoot voltage)(2)
91、Response time depends on the temperature.(In lower temperature, it becomes longer.)(3) Brightness depends on the temperature. (In lower temperature, it becomes lower.) And in lower temperature, response time(required time that brightness is stable after turned on) becomes longer.(4) Be careful for c
92、ondensation at sudden temperature change. Condensation makes damage to polarizer or electrical contacted parts. And after fading condensation, smear or spot will occur.(5) When fixed patterns are displayed for a long time, remnant image is likely to occur.(6) Module has high frequency circuits. Suff
93、icient suppression to the electromagnetic interference shall be done by system manufacturers. Grounding and shielding methods may be important to minimized the interference. (7) Please do not give any mechanical and/or acoustical impact to LCM. Otherwise, LCM can not be operated its full characteris
94、tics perfectly. (8) A screw which is fastened up the steels should be a machine screw (if not, it causes metal foreign material and deal LCM a fatal blow)(9) Please do not set LCD on its edge.Product SpecificationLM230WF5Liquid Crystal DisplayVer. 0.3Sep.,19, 201129 / 29Since a module is composed of
95、 electronic circuits, it is not strong to electrostatic discharge. Make certain that treatment persons are connected to ground through wrist band etc. And dont touch interface pin directly.7-3. Electrostatic discharge controlStrong light exposure causes degradation of polarizer and color filter.7-4.
96、 Precautions for strong light exposure When storing modules as spares for a long time, the following precautions are necessary.(1) Store them in a dark place. Do not expose the module to sunlight or fluorescent light. Keep the temperature between 5C and 35C at normal humidity.(2) The polarizer surfa
97、ce should not come in contact with any other object. It is recommended that they be stored in the container in which they were shipped. 7-5. Storage7-6. Handling precautions for protection film(1) The protection film is attached to the bezel with a small masking tape. When the protection film is pee
98、led off, static electricity is generated between the film and polarizer. This should be peeled off slowly and carefully by people who are electrically grounded and with well ion-blown equipment or in such a condition, etc.(2) When the module with protection film attached is stored for a long time, s
99、ometimes there remains a very small amount of glue still on the bezel after the protection film is peeled off.(3) You can remove the glue easily. When the glue remains on the bezel surface or its vestige is recognized, please wipe them off with absorbent cotton waste or other soft material like chamois soaked with normal-hexane.
